My wife's 2000 Trailblazer sqeaks pretty bad when you push down on the rear rack. It's hard to figure out where the sqeak is coming from, but I think it is the left side swingarm. I have greased the zerks multiple times. I have lubed the shock bushings, etc. Still the squeak persists.

Do I have a bad bushing/bearing on the left side swingarm? How do I tell?

Thanks.

 

Check to see if it is coming from either the top or bottom shock mount. My Blazer's top shock mount bushing squeaks pretty bad. If that is it, nothing to worry about really. There is no way to grease it that I know of.
