I installed all poly bushings on my turbo limited back in 89, and the ride went from cushy to brick. the 5.0 mustangs rode more comfortable than my T_R limited!!! Like others said, the stock bushings allow movement. changed out just the two on the pumpkin with rubber and the difference was night and day. Wanna sell the rear bar, if its a stock style bar?
With that sway bar gone, the ride is very nice, despite the poly bushings. I'm more convinced that there was some binding going on or something. I'm not looking to sell it yet- want to drive the car a few more weeks/months before I'm confident that it'll be gone for good. Thanks, -Bob C.
