disconnect the end links and drive to try to repeat the "clunk". If it goes away, you've found it.Where is the best place to get these endlinks?
I just had my LCA's replaced and while the steering feels tighter I still have a clunk, had it at another dealer and they couldn't figure it out, I'm going to bring the car to my friend's shop and get it on a lift and see if this could be the culprit.
If so...I know exactly when I wrecked 'em - when we had that 28" blizzard the next day I drove 10 miles over snow packed roads that felt like a mine field covered w/ craters and speedbumps even at 15-20 mph. Probably had 2 years worth of bumps packed into one short drive there and back!
