Engine/Transmission (1998.5 - 2002) Rear End Vibration

[kurtl]

I recently installed new ring and pinion in my 2001 and found that the stock set up was loose and bearings were siezed. I was told it would have blown in about 15000 miles. ( had 36000 on it).

After about 1000 on the new ring,pinion and bearings I am getting a vibration and growling sound when turning slow. I changed the oil again and added more posi additive and still no luck. Any ideas?

Noises

If you didn't do the new install yourself, I'd go back and see what the people who did the work had to say. Setting that issue aside for a moment, I'd start thinking about a miss aligned housing. The machining work on the housing itself could be causing loads which have nothing to do with oil changes. Bearing surfaces are machined to run/work in proper alignment with each other. When any one component is mis-aligned or too tight can bring about premature wear. Thus the sounds you are hearing. I would not wait very long in finding the answer to your situation for I believe these sort of situations do not fix themselves. Good luck. Dave
