swapping a 14 bolt

[BIGJIMMY]

My axle shaft broke at tcc and it destroyed my carrier and spider gears also, so the total cost to fix the 10 bolt is around 350, i can get a 14 bolt for a lil under 150, what will it take to get that swapped to my jimmy, and will it end up being cheaper?
I figured that 2 rims in the back, changing the yoke on the driveshaft, and maybe an ebrake cable? what else would i need to do?

[sasquatch]

you can get a conversion joint for the different yokes instead of changing it.

i would think it should bolt in but we'll wait for sharpe

[bcolman]

you might need to do a brake job on the 14 bolt, you atleast need to check them out, and you dont have to change the yoke, you can just do a conversion u joint, you might have to shorten your driveshaft, you might have to do something with the braking system, i am not sure if there is a big enough difference between a 10 bolt and a 14 bolt to have to do anything though.

[Doug Krebs]

want to buy a disc braked 14 bolt? I have one in my garage...

[BIGJIMMY]

how much and will it pass inspection, ineed an ebrake

[Doug Krebs]

No ebrake.... I never have had a problem getting my blazer inspected without one.

You should swap out the front disc's and bearing hubs too 8 lug to match.

[Doug Krebs]

Also, if you don't want to go that route, I have all the drum brake hardware that I can warranty out for my old setup.

[BIGJIMMY]

if i do this i will eventually, i need something that will be strong and not cost an arm and a leg, send me a pm and tell me how much you want, what kind of gears does it have?

[Sharpe]

Going with Doug's axle would be a good choice. It is ready to bolt in so you dont have to worry about anything except the e-brake situation if it really concerns you. For the record, 3/4 ton 14 bolt housings will bolt into a 1/2 and 3/4 ton truck (like your jimmy) but a housing from a one ton truck would have to have the spring perches cut off and relocated 2 1/2" wider.

[stx4wheeler]

i would just fix the 10 bolt since you dont do much wheeling on rocks, and you would have to convert the front axle to 8 lug, it will most likely be cheaper.

but if you dont ever want to worry about it again then go for the 14

[BIGJIMMY]

will the same ubolts bolt up also?

[Sharpe]

No, you will need u-bolts for a 3 1/2 tube axle and new spring plates too.

[BIGJIMMY]

can i get those from a junk yard or are they hard to find?

[Sharpe]

You can buy a kit from offroaddeisgn.com that has u-bolts and plates for a decent price.

[bcolman]

if you have 373 gears i have a set for a 10 bolt that i will sell you if you decide to stay with the 10 bolt

[JB]

Did you like wheeling on the rocks? I really did not get to see you out there much. Do the 14bolt. I can hook you up on new brake shoes (or cadillac e brake calipers if you buy doug's axle), and u-bolts, and the conversion joint.

[BIGJIMMY]

well if doug would get back to me i would tell you, i definately want to go with the 14 bolt. when you mean hook up does that mean real cheap or at a discount?

[jerryg79]

well if doug would get back to me i would tell you, i definately want to go with the 14 bolt. when you mean hook up does that mean real cheap or at a discount?

he doesnt have a computer at his house last i checked. He probably wont be back on till tomm.

[bcolman]

send me brother (colman on the boards) a message and he should be able to give you krebs cell number

[Doug Krebs]

I gots a computer again... I replied to him already.

[mudtoy67]

want to buy a disc braked 14 bolt? I have one in my garage...

Did you dismantle the blazer? :confused2

[JB]

well if doug would get back to me i would tell you, i definately want to go with the 14 bolt. when you mean hook up does that mean real cheap or at a discount?

i know your cheap man, but nothings free, ill take care of you as much as I can

[BIGJIMMY]

ill know tomorrow what im gonna do,

[colman]

if you just need to get back onto the road you could probably find a 10 bolt for cheap that will bolt up while you acquire parts

[BIGJIMMY]

naa the truck is gonna sit all summer while I work at a camp. So now is a perfect time for it to break with school about to be out. Im just gonna be patient and do it right.

[Eckert]

there is a complete pair of axles from a 82 3/4 ton chevy local to me back home. front 10 bolt and rear 14 bolt, both 8 lug for $200. Last time i checked they were still for sale. want me to check up on them?

[BIGJIMMY]

YES PLEASE! r u from austin?

[fbronco86]

Did you dismantle the blazer? :confused2

It was probably for his dream buggy :gigem:

[Eckert]

YES PLEASE! r u from austin?

close enough, PM sent

[BIGJIMMY]

whats the difference in a 6 lug and an 8 lug 10 bolt for the front axle?

[bcolman]

whats the difference in a 6 lug and an 8 lug 10 bolt for the front axle?

the only difference it the outers.

[RCcola55]

whats the difference in a 6 lug and an 8 lug 10 bolt for the front axle?

two threaded pieces of metal :flipoff2:

[Gearhead61]

I think it's just that... one is 6 lug one is 8. the 8 lug parts will swap over to the 6 lug so you can run the same bolt pattern front and rear.

EDIT: Missed the 3rd page of this one... don't i feel silly :rolleyes:

[BIGJIMMY]

I got one from my neighbor, its got 410s with a posi for $150. and its the best lookin axle out there.

[colman]

is it the gov lock, ive heard really bad things about those, and if one of the others has a detroit i'm interested

[BIGJIMMY]

what did you hear, cuz i think it is

[agjohn02]

sharpe calls it a gov-bomb. no worries, ive got an extra for you.

[colman]

ive heard other people call them that and worse. what ive heard is when they go they really go, no personal experience.

[Doug Krebs]

CRAP! I just had a page written out and hit some random key that erased it all... Should have done it in word. Anyways I'll simplify it....

Another downside the the gov lock is it can't accept a detroit.

I'd suggest doing disc brakes if you do any kinda of mudding or anything where crap might get caught in the brakes. Drum brakes on a 14 bolt require you to remove the axle shaft first. Then you get to remove the spindle nut and remove the entire drum/bearing hub assembly. All this just to get crap out. I did it many times...

Also, the crap caught in there will make the axle seal leak and drip onto the shoes. This makes for fun braking. I probably replaced 4 seals in the southside parking garage. They loved me there.

Disc's should be around $200 to do.

Only downside is no parking brake, but you can get a line lock which is kinda halfassing it unless you get and expensive one. You can also get the caddy calipers which have a parking brake provision, but people have mixed reviews on them.

I put a adjustable proportioning valve on mine, but I'm not sure it does much. I think I have issues other places...

[agjohn02]

Another downside the the gov lock is it can't accept a detroit.



this is how i was introduced to the gov-lock. split the case open and realized a detroit wasnt going to fit. its pretty neat how they work. i played with it while i had it open. luckily, i had an extra open carrier sitting around for the detroit.

[BIGJIMMY]

well it doesnt have a gov lock, just a posi in it. i looked in the glove box and it only said locking differential. The guy said it doesnt have a gov lock in it, and he knows his stuff. Whats the best place to get a disc brake set up? and whats a line lock?

[BIGJIMMY]

oh it was fun getting that out too, laying in the mud with dog crap everywhere and no air tools, it was worth it though

[Doug Krebs]

A gov lock is a posi! If it says locking differential in the glove i'm almost 100% sure it's a gov lock.

[Doug Krebs]

Whats the best place to get a disc brake set up? and whats a line lock?

You buy it in pieces...

Brackets are on ebay and probably most offroad sites have a vendor for them. There are alot of different shapes/designs, but they do the same thing.

Rotors/calipers you get from a parts store, internet, whatever.

A line lock is a valve that holds brake pressure in the system. Drag racers use them for burnouts. You can also use them for cutting brakes, etc...

There are two types, electric and manual. Many different opinions on the electric one's as some say they can leak down, or if they loose power they shut off. When they are on they use current, so eventually they will run your battery down. Some people say they leave them over night and have no problems. They are cheaper ~$40.

Manual one's are supposed to be more reliable. Some people have had luck with swaglock? valves. Mico are expensive, but build very well.

I have no experience with either.

[BIGJIMMY]

what r the chances of it breaking with normal abuse?

[bcolman]

i dont know much about the gov locks, but i have heard that when they go they go bad and sometimes they take the housing with them.

[agjohn02]

i didnt think they would stay on for more than a minute or two? the solenoid heats up and disengages is what ive heard.

[BIGJIMMY]

im lookin at disc brake brackets on btf, should i go with weld on? How much is a proportioning valve? and how much do you think calipers and rotors are from a 1/2 ton?

http://www.bluetorchfab.com/shop/product_info.php?cPath=107&products_id=354

[agjohn02]

3/4 ton rotors $47.98 o'reilly's
3/4 ton calipers $71.98 o'reilly's
brake pads $10.99 o'reilly's
caliper brackets $45.40 ruffstuffspecialties.com


total= $176.35


plus brake lines

http://www.bluetorchfab.com/shop/product_info.php?cPath=107&products_id=354

Want me to come do it for you? :flipoff2:

All the conversions I've seen use a rotor from the front axle of 3/4 ton 4x4. It needs to be 3/4 to be 8 Lug. I'm pretty sure calipers are the same for 1/2 and 3/4 ton 4x4's.

Each rotor is ~$30 for the cheap ones and loaded calipers are ~$30 each. So thats ~$120.

For my blazer I used bolt on brackets that I bought from a guy in the club many years ago. The other axle I have also has bolt on brackets. To me bolt on brackets seem cleaner. I think the bolt on brackets are ~$60.

Look in summit for adjustable proportioning valves. They are under $40 I think.

[agjohn02]

weld-on brackets are way cleaner.

[agjohn02]

why you selling out all of a sudden krebs? i tried to buy all that from you 9 months ago.

[Doug Krebs]

weld-on brackets are way cleaner.

Do you get rid of the stock flange? If so I agree, because the bolt on brackets need spacers that can be goofy.

I do like the brackets I have on the blazer. I bought them from cody as he made two sets at the time. He copied some design that was pricey. It has a clocking ring that bolts to the stock flange. Then two little spacers and than the caliper bracket.

Most of the ones I've seen have 4 large spacers, and then the big caliper bracket.

[Doug Krebs]

why you selling out all of a sudden krebs? i tried to buy all that from you 9 months ago.

It's the two axles I have for the buggy, which realistically won't happen for probably 4+ years. I'd rather have the money in the bank right now than them holding down the floor.

[agjohn02]

Do you get rid of the stock flange? If so I agree, because the bolt on brackets need spacers that can be goofy.


yeah, i cut the flange off. ruffstuff makes the best looking bolt-ons though. they have a bend in them so you dont need the spacers. i cant stand most of BTF's stuff. its trying too hard to look hard. i like plain. its doesn't scream, "I BOUGHT THIS FROM BTF!"

[Sharpe]

My front linelock in pigpen will hold for a good while. I use it all the time out on the trail and I've left it engaged for several hours and it was still holding when I came back. Its just a Jegs brand electric one, nothing crazy.

[DRAGOONRANCH]

My super secret rear line lock that was unveiled in the comp at TCC was the cheapest and easiest way I have seen done before.

Step 1. Acquire electrical problems under hood.

Step 2. Tell Rowdy of said problem w/ wiring (especially if he had anything to do w/ installing said wiring.

Step 3. Let him crawl under hood and proceed to break the front brake line off at the master cylinder. :gigem:

Cost of flaring tool: 10 bucks at your local parts store
Cost of time to reflare line: 20 bucks (I really value my time w/ myself ;) )
Cost of a Rowdy Special line lock in your first TCC competition?

PRICELESS

In rowdy's defense, the severe body flex may have been the culprit here also. :flipoff2:

[Reckless]

1. Had flairing tool for you to borrorow.
2. Wiring had to be bad fuse.
3. BODY FLEX
4. I'm Just good like that

[BIGJIMMY]

how far back do you weld the brackets to get the correct spacing? and for rims, what kind of back spacing do i need?

[DRAGOONRANCH]

1. Had flairing tool for you to borrorow.
2. Wiring had to be bad fuse.

4. I'm Just good like that


1. The cost of a trip to town on $3/gallon diesel makes this a mute point
2. You remember the wires wrapped around the steering shaft? ;)
3. No **** Sherlock
4. No argument there. :flipoff2:

[DRAGOONRANCH]

how far back do you weld the brackets to get the correct spacing? and for rims, what kind of back spacing do i need?


I plan on mounting the hardware first, then welding them on when I get around to doing the 14b in the barn. As for rims, thought of going H1's?

[BIGJIMMY]

are they 15 in? cuz i got 15 in tires and dont think i can swap them out for 16s, plus i heard that 16s dont hold a bead very well. where do you get them at?

[mudtoy67]

H1 rims are 16.5" diameter and are a double beadlock wheel, so you don't have to worry about ever losing a bead. You can find them all over, mostly people get them military surplus and then resell them.

[bcolman]

the biggest problem with the h1's is the backspacing.

[DRAGOONRANCH]

which can be fixed rather easily w/ a torch, welder and recenters from usa6x6. :gigem:

[DRAGOONRANCH]

and a grinder if you want it to look good.

only if your cuts look like you did them w/ a titanium toothed beaver. :flipoff2:

[agjohn02]

i just think a machined looking edge looks better than the best torch cut. i grind plasma cut edges. im a freak like that.

[DRAGOONRANCH]

you need to lay off all that meth you picked up in Clayton, then maybe your hands wouldn't shake so much. :flipoff3:

I am not tryin to say I could do any better at this point and time, but with some torch time I can get it pretty close to a machined edge. (Atleast I hope I can again.)

[agjohn02]

let me rephrase... i grind CNC plasma cut edges...

[DRAGOONRANCH]

can you spell OCD???

[stx4wheeler]

paul just go get a pair of some 15 in 8 lug wheels from sunnit or discount, that match your wheels. Will his 15's hit anything with the disk swap?

[DRAGOONRANCH]

yeah, it gets pretty tight on 16"s IIRC

[agjohn02]

15's might fit with caliper grinding, but i dont like that idea.

[Doug Krebs]

15's might fit with caliper grinding, but i dont like that idea.

I think 15's do fit without caliper grinding. You can use a half ton caliper, which uses 15" rims.

[agjohn02]

ah, yes. i forgot its 1/2-3/4 ton stuff. its one ton brakes that you have to grind for 15's.

[BIGJIMMY]

well guys it kinda suck but i cant afford to do the disc swap, just dont have the cash , and my woman needs a ring. but in about a year i will prolly do it.

One thing tho, the spring mounts on this axle are underneath the tube, can i just flip it over or do something to make it bolt on top of the spring?

[Reckless]

cut off old spring perch, weld on new one on top

[bcolman]

it may just be me but i didnt know there were spring under 14 bolts. are you sure you dont have it upside down?

[Sharpe]

:laughing: :laughing: Flip the axle over buddy.

Unless some jeep homo had it in his truck before hand no 14 bolt ever came in a sprung under appilcation.

[BroncoJo]

Its not just you I dont remember any spring under 14 bolts either.

[BIGJIMMY]

where it bolts to the mounting bracket is under neath, not the spring,

i think he's right. the wheel cylinders go on top.

[Doug Krebs]

where it bolts to the mounting bracket is under neath, not the spring,

dude, where do you live? I think you need guidance. I've never heard of a spring under 14 bolt. You did say you got it out of a chevy truck right?

Make sure the pinion is on the bottom.

The "mounting bracket" is called the spring plate and yes on 14 bolt full floaters they all came like that. I dont mean to be a dick but you dont know what your talking about so go buy a membership and search for all the info you need on pirate or coloradok5. Hell, try searching here. Like I said, I'm not trying to be rude but the questions you are asking are EXTREMELY basic and have been answered a thousand times over.

its not even tuesday.... what a week

[BIGJIMMY]

Yeah i just call things different, i dont know the technical name for stuff, but i already found the answer to my question on offroaddesign.com. I know the freakin axle isnt upside down, im not that stupid, Ive already read most of the stuff on pirate and some on ck5.

BTW- Did you see that wierd looking guy on the moped behind me when I drove past you today?

[agjohn02]

i think i did. i see a lot of weird people go by here though.

funny story. just after you drove by this guy that lives down the street from me came by. he's nutty as a squirrel turd. he wanted one of us to buy him a beer. he had the money already. dudes a Vietnam Vet and in bad health. he said the lady at the store wouldnt sell him a beer since he had a stroke this morning. we were like, "whoa, a stroke?" he says, "yeah, its not like i had it 10 mins ago. it was this morning. i need a magnum."
