Were you getting the vibration before? Did you mark the driveshaft, differential flange and yoke before removal so they were assembled in the same place? Are the u-joints lubricated and moving freely? What kind of condition are the tires in? Have you isolated anything beyond the center support bearing?

I didnt notice the vibration before . I did mark everything before disassembly ujoints are moving freely. Tires are new. The center bearing was making a grinding noise that is why I replaced it. I am going to put a dial indicator on the drive shafts today. How much runout is allowable? If the ujoints are moving freely could they still be bad?

Ok I put the indicator on the drive shaft I checked each drive shaft in 3 places 3 inches from each end and in the middle the readings were as follows

Front Drive Shaft: .oo8, .007, .oo8

Rear Drive Shaft: .030, .026, .015

readings are from front to back any help would be appreciated

Maybe you need to have the drive shaft rebalanced.
