Pulled the rear driveshaft last night to have a look at the sye flange. Looks like the installer cut the shaft too short...there's only about 3/4" of spline on the end. There's a bit of wear on the splines which is why the flange wiggles a bit. The flange bolts to the shaft with a washer on the ID that is only held in with a snap ring, so it doesn't help any with keeping the flange straight. Think if I welded the washer to the flange it would hold the flange tight enough to slow any further wear? Or would the wiggle be enough to cause the bolt to back out?
