Having issues with the driver side.

Some background information, 2007 Lexus IS250 was involved in a pretty significant accident where the Left control arm needed to be replaced. As well as the quarter panel and the bumper had to be realigned.

Car drives straight with no issues, no significant road noise. Replaced rotors, brake pads, and even tried to switch the rims but no luck with getting rid of the noise. Took it to a mechanic and he couldn't diagnose what was wrong.

Noise only occurs when I'm driving over a speed bump going more than 5MPH, only from the driver's side. It's a pretty significant popping noise, I thought it might be the CV joint but mechanic said it was fine. Maybe this is suspension related? What should I be looking to replace at 100k miles?

Any help would be greatly appreciated, thank you for reading!

 

Check your bushings and the suspension.
