My car always had a weird squeak in the rear suspension. I thought it might be leaf spring bushings. It ended up being the rear stabilizer bar bushings. They were totally binding up on the bar in 4 locations. I removed the bar, and then cleaned the areas where the bushings rode on the bar. I then lubricated the areas with synthetic chassis grease. I put it back together, after refinishing everything, and no more noise at all.
