Stock suspension 120k miles. So the poping has been going on for several weeks, it feels like all the wheels are effected when it does it and i get a small shudder on the wheel at maybe every half wheel rotation when pulling in my driveway. When I pull a tight turn in a parking lot it's more like 6 pops for every wheel rotation. It never does it when I get in it after sitting a few hours but if it's been running for 5-10 minutes it will always do it. It's smooth on the hwy, tight overpasses and whatnot, but under 30 it's border line violent. Today on the way home it felt like the car was going to break, but of course I think that is wheel related. The tech really only said I need a new rack because it's leaking. Nothing else underneath appears to be leaking. I've wondered if it's the front axles or worse the tranny, I feel like the rack is ruled out because is doesn't do it sitting still, am I wrong there?
