Finally got my cruiser back after the clutch job . However as soon as I got above 40 I noticed a nasty vibration. Got out made sure hubs unlocked and was in 2hi. Figured it was one of two things, bad u-joint or rear ujoints out of line. (I don't even know if the latter predicament will cause vibration). I took the rear drive shaft off, cause it was out of line, and noticed that on one axis of pivot it was hard to "bend" the u-joint back and forth, it would bind about halfway through its travel. So I promptly pumped some grease through it to see if that would help. It didn't.  rove 2.5 hours at 60 mph home today, figuring I need to rebuild/replace. Noticed that this u-joint is welding to d-shaft, thinking rebuild is better. Can I just take it apart and order individual parts from SOR/Toyota? Looks like you can on SOR, but prices are too great. What wears out in these things?
