I recently had a mishap with a very tall sidewalk and had to change a bent cradle arm. Now, there's a noise coming from the front left wheel almost like a knocking sound as well as intermitent clicking. A mechanic friend of mine said that it's probably the bushings and that his father and another buddy of ours are experiencing the same problem in their models all 2001 and below. He suspects that the bushings are particularly suceptible to damage. I'm just wondering if anyone else have come across these problems.
