[s-cars] Driveline issues?

[Alvin Labonite]

Hello:

This back and forth movement/jerking of the car is getting annoying. It 
happens when crawling in traffic usually on 1st and 2nd gears at a speed of 
around 15-20mph. It's worst when letting off throttle. I don't hear any 
clunking or anything when it happens.

I have new engine/tranny/snub mounts as well as new sub frame bushings. What 
else could it be Center diff mount?

Thanks for any input.
