I figured it may have been the rear control arms, but I had the squeak before and after I installed some steeda LCA's, with plenty of the grease they supply.

I'm thinking it might be the swaybar bushings?

The car gets driven all winter and it rains here for most of the spring and fall.

Anyone else? I'm just going to try to get some silicone or graphite into the swaybar bushings (the round ones that capture the swaybar) and see if that works, perhaps drop the rear control arms out and regrease.

 

Take a look at Spohn Performance. They have a 14oz tube of GM Polyurethane & Chassis Grease that works great. The SKU# is 902. Cost is $21.55 shipped to your door and WELL worth the $'s.

Fixed it.

The caliper and pads were bouncing up and down on the steel shims on either side of the carrier.

Put Aerosol CRC disk brake quiet on the carrier, on the shims, on the brake pad backing plates, and on the brake caliper piston.
