I just noticed that my drivers side upper rear control arm bushing (spherical joint bushing) is now loose. The result is a sound that I have never heard before when slow starting and stop -- KLUNK! After having the wheel off this weekend it is noticeable that it now slides in and out -- the sound coming from the forked end of the control arm are slamming into the top of the wishbone assembly. The dealer does sell just the bushing assembly $56. but, they recommend replacing the whole control arm with new bushings in place $670. Apparently, this is a common problem and there have been several redesigned versions of the complete assembly. Question: has anyone replaced just this bushing set and been a safe/happy money saving driver? It is definitely the easy way out.
