My personal experience with the Dynapak brand was very bad. It actually sounded worse than the one I replaced. I eventually replaced it with one from Precision and that one seems to work real well. Price ranged from $90-$99 for each one. Just a lil heads up.

I haven't had any issues with Timkins.

just had my right one replaced...i believed they replaced it with just a GM one cause my dad works at a caddy dealership...and they had the left bearing apart and they apparently didn't get it put back together right because there is grease all in the inside of my wheel well and everytime i drive over even the slightest crack in the road there is a clicking noise. sounds like a chain dragging on the ground...my dad will take it in tomorrow AGAIN to get if fixed....gah
