My '00 300m has just turned 100k (km) or 62k miles (vast majority in city driving). I guess that's about 10k miles per year. Some significant periods were spent driving over road sections that were undergoing lengthy re-construction. Over time I've been noticing/feeling increasing knocking coming from the front end. Driving for a few months with a badly warped front rotor(s) I'm sure didn't help.
So while the steering still seems very tight, the knocking has to do with driving over un-even pavement, dips, etc. It's not really noticable unless you pay keen attention (it can be hard to separate it from general road noise). While I'm familliar with and have worked on late 1960's C-body suspension and early 70's B-body suspension, I'm not familliar at all with the suspension configuration of a 300M.
What is the most likely suspension part(s) that is wear-prone that is probably causing this knocking? Ball Joint? And what does a dealer typically charge to replace it/them ?
