Side to side motion in rear of 2000 EB w/o air suspension

[Steve McGarrett]

Greetings from Omaha!

I recently had the lower rear trailing arms replaced after the OEM arm on the driver side rusted through. I had a shop do this and have noticed since then that when I get on the gas the rear of the vehicle "torques" to the right and when I let off it does the same thing to the left.

Is there a certain component that I should check that would cause this? I haven't been able to get underneath it as it's covered in snow/ice/crap so if possible I'd prefer to zero in on the problem versus digging around.

Thanks in advance!

Could be a lot of things if theirs play in the new trailing arm bushings, that would do if. Also worn shocks/ springs can also cause a sway motion. Another item to check is for wheels proper tightening torque. Check tire pressure, and tread. The fact that it happened right after repair leads me to parts not a proper fit/tightness of mounting hardware, or as usual with most aftermarket parts, a poor fit.
