I lurked this forum for some tips. Now a member!
2000 GP 3.8L (non supercharged).
I had some clunking noises in the front end. Did some research here and replaced the front control arms on both sides. Noise gone, handles much better.
The control arm bushings were probably shot. The ball joints may have been too. I have no idea how to tell but the car handles much better and no noise!
I love my GP!!!
