Jun,
There are a ton of scenarios. Assuming the car has not been wracked or
misaligned, I would suspect rear trailing arm bushings (RTABs). If they
wear, the rear starts to provide steering inputs as the suspension
compresses/rebounds.
The replacement is very simple with the right tool. 30 minutes/side +
another 15 to get the car in the air and remove the rear wheels. You may
need to re-align the car if the rear toe brackets were not marked and
bolted back exactly as they were.

HTH,
