Hi all,
I have had a drive train vibration problem for awhile and I can't seem to solve this one. Unfortunately, I don't have a very good baseline since I bought this cruiser when it wasn't really running (pouring oil out) so I never really had a good feel for what it was like before I started working on it. I put on an OME Medium (removed a leaf) and replaced all of the gaskets so it stopped leaking.
At this point I had a vibration issue at 25mph and some after. Here is the order in which I tried to address the vibration or just general maintenance that I would hope would help. Replaced all U joints (front and rear), 2 degree shims in the front, tried shims in the rear (fat part facing toward the rear of the vehicle) made vibration worse, measured the difference in TC flange and differential flange angles (rear differential is 1.5 degrees lower that TC), had the drive shaft balanced both front and rear, drove without rear drive shaft (no vibrations while doing this), reasealed transfer case, replaced clutch, did rear main and resurfaced flywheel, rebuilt rear differential.
So what are your thoughts now? Should I try the rear 2 degree shims with the fat end facing the front? That would even out the driveline angles (but from what I understand the rear diff should be 1 degree lower). Have the rear drive shaft rebalanced or at least checked again, Call Tom Woods and go with one of his? Any suggestions would be totally welcome. Thanks
