Strange Vibration
#1

Recently replaced left rear wheel bearings and hub bearings. Now, when engine is under slight load I get a vibration. If I accelerate slightly it goes away or cruising on level road feels fine. If going uphill and engine starts getting slight load is when vibration appears. If transmission downshifts from overdrive and RPM increases it goes away. Anyone have any suggestions they would be greatly appreciated.

1. Consequence
When replacing the hub carrier bearings, the bearings must be shimmed to give the correct end float and the shims on the pivot pin must be replaced in their original position. Provided this was done you shouldn't have introduced anything to give rise to vibration other than the remote possibility of a bad bearing.
2. Co-incidence
A regular cause of vibration is failing rear suspension A Frame bushes and another is a worn Jurid coupling on the prop (drive) shaft.

I can't figure out yet where vibration is coming from. I just feel it through out car. No noise associated with it. I replaced the hub carrier shims where they came from and marked mounting bolt for correct placement. My biggest problem is this only happens under a slight load. If I get a chance today I may try jacking up rear and running. The vibration is just steady until car downshifts to increase load or road levels off. Then I can runs miles with no consequence
