Had the same issue. Clunk over bumps. The track arms were probably the culprit, but I opted to rebuild the entire suspension. While I was at it.

Concur that replacing just the track arm is a 30 min/side job. Super simple to do. And if it solves your problems, then perfect.

I'd also take a look at the rear sway bar bushings. There are even easier to replace and a lot cheaper. Could try replacing those 1st before you go after the track arms. Might solve the problem for less money.

But I will say, a full suspension rebuild has done amazing things for the cars driving feel. Feels like a new car!

Good luck.
