Is there a way to tell what gearing I have without pulling the carrier?
2010 VW Jetta - DD, 5 Banger, 5 Speed, 1000 Watts of sound!!
1979 Ford Bronco Custom - 400/T18/205.. 35" SSRs, 4" lift, Rancho 5000s, 200 watts of sound!!
Not as accurate, but if the tird is running, here you go.
With GPS, get on highway. Go in straight line, in 4th gear. Record mph and tach setting. Go home, measure OD of tires. Now here is the part where I am going to confuse you.
Now, mph = speed, D = the diameter of your tires
(MPH * 5280)/(3.14*D*60) = revolution per minute at the wheel <--- fixed this
Now, tach = RPM's on your tach
tach * (Tranny's 4th gear ratio, I think 1.0 for you) * (TCase gear, should be 1.0) = Revolutions per minute at the output of the tcase
Now divide Revolutions per minute at the output of the case by revolution per minute at the wheel.
Yours is mostly likely 3.55, but could be 4.11
