RR wheel area weird noise...
First thing in the morning when the vehicle is cold, and after I press on the brake once it makes a whoom..whoom sound coming from the RR wheel area. Will go away once vehicle is driven more than 1/4 mile. This is on my GSLSE and my '81 GSL did this also but over time it got worse and it did it practicly everytime I went around a turn and pressed on the brake. Since this has happened with 2 of my FB's, I would guess that others have experienced this too...Whats going on?????

Remove the caliper and clean/lube the slide pins. If they get gummed up, then they have trouble sliding back away from the rotor when released.

It may be bearings, a loose brake component, bent axle or bent wheel. You need to narrow it down one by one through elimination.
Do the easiest first, swap the wheels front to back and see if it follows the wheels. Then move on to the brakes. Go over them again since you just did work on them something may be loose. A bent axle can be found by putting the rear up on jack stands, pull the wheels and start it up in first gear and let the hubs spin. Take out a marker and hold it steady and draw on the hub. If it doesn't draw a perfect circle centered on the hub then an axle issue may be present.
Bearings could also cause some wobble and possibly the noise as well.
I'm betting its a bearing issue if you sure the brakes are ok. Bending the axle requires hitting some hard like a curb with the wheels.
