I bought a 2007 Cobalt LT this past July '07.

On September 6th, '07 I had taken my car in and I had my rear passenger side Suspension Insulator replaced @ 2200 miles (as I was complaining of a clunking noise).

I just got my car back yesterday (Feb.8th,'08) and again I had both my rear passenger and driver's side Suspension Insulators replaced, a whole new passenger side rear shock replaced (they noted my current/original one was "leaking"), and a new Serpentine Belt put on ( as I complained of squeeking upon acceleration). All this at @ 10,100 miles.

This was all warranty work and cost me nothing so I'm not complaining - though I was just curious if anyone has had the issue of these Rear Suspension Insulators failing on them, let alone twice w/in 8,000 miles - and with only 10,000 miles on the car?!

I don't race, and I don't drive hard at all, nor do I abuse it on overly bumpy roads.

(as a side note, I believe the suspension insulators are comparable to the CV Bushing on the suspension on Cavaliers - correct me if I'm wrong in my thinking)

Thanks for any input.
