Haven't noticed anything on the rear, but my front left squeaks over 
bumps also. I think the list has covered this as an A-arm bushing 
problem, but more of an annoyance than anything. ie: It is safe to 
ignore it for a while. (which is what I've done.) Haven't noticed any 
extra "play" in the suspension, so I'm not worried.
