After the discussions on driveline vibration & my frustration in not 
being able to isolate the problem I picked up a good used diff hoping it 
would solve the problem as a last resort.  I have it on my work bench 
checking the basics waiting to swap it out. I've been driving the car 
hoping the culprit would eventually fail and I would know what the cause 
was. Well finally the other day I started to hear a squeal on 
acceleration. I isolated it to an in-board u-joint drivers side. After 
removing it I discovered a cracked bearing cap. I either cracked it 
installing it or it failed during use, I'll never know. In either case, 
it seems to have solved the problem. I took the car out for a drive with 
speeds over 70mph & all is fine. I checked the U-joints many times & did 
not detect any looseness , I guess the cap , even though it was cracked 
wasn't loose  but was either out of center or not flexing easily.
The only way I could have discovered this would have been to remove the 
axle & see if the joint flexes easily. Mine was almost locked. That 
would explain why it was intermitant but would vibrate under load.
Hope this helps
