Wheel Question Again... the saga continues

May also be a worn front yoke or worn tail bearing/bushing allowing the yoke to oscillate. Over-tightened front C-beam bolts can cause the bearing/bushing to incur accelerated wear.

Suggest:
1. Check with the previous owner to see if the driveshaft has been removed, or
2. Use 2 post lift, in neutral, turn the tires & check driveshaft run-out near both front & rear u-joints and in the middle.
3. check for excessive movement of front yoke. If noted, will require removal to determine if yoke, bearing/bushing or both are a fault. If the yoke is to be replaced, contact Bill Boudreau at www.ZFDoc.com. The correct Spicer yoke can be difficult to find. Bill can tell you the difference from a commonly available yoke which is not quite right.




None of the above checks will be difficult or expensive and may help to eliminate a distinct possibility. Looks like you have been through the wheel/tire possibility pretty thoroughly.

Good luck.

That's way more effort than doing a drive and swap wheels and tires. If the swap of wheels and tires makes it go away all is done!

I thought I was the first to mention the "service slip-yokes" supplied by most aren't any better than a 100k used one. I've a slip-yoke that's been used many times for correct fixes that only requires the use of a 1330/1310 conversion joint and the removal of 30mm from the end. It's got the correct major/minor spline dimensions. Still pretty readily available.
