The stabilizer bar rotates on the stabilizer bushings (usually 2 bushings required) be it front or rear of vehicle.
Most new sway bar bushings are split so they can be R & R easily. Remove clamp from bushing, slip or cut old bushing out, slip new bushing in and replace bushing clamp.
The sway bar bushing is located inside the the clamp that secures the sway bar to the frame. They use a busing to allow a little flex in the sway bar but not enough to cause a clank sound everytime the bar is flexed. So if the bushing is worn or gone your sway bar will make a bunch of clunk/clank sounds when the car is in motion.
A replacement part should be of the same dimensions.
Not extremely, but it will cause a noise (sometimes) when going over bumps and premature tire wear.
Probably a control arm bushing, possibly a strut mount or stabilizer bar bushing. Mine was the control arm bushing, 2001 Windstar Sport pkg.
Saturn S series vehicles do not use a Strut arm... nor do they have a Strut arm bushing. I'm assuming your referring to the sway bar bushing in the center of the lower control arm. This bushing is not serviceable alone, the replacement of the entire lower control arm is needed if the bushing has failed.
Its a 100.00 part that we dealers charge you 500.00 to fix....
Stablizer
Drive the car onto ramps then use a jack to raise the right axle and make some space between the axle and stablizer bar.
The bushing on the track bar. http://lukeslink.com/ this link has the fix.
Yes, rear stablizer bar links are a very common cause for rattling, knocking in the rear of these trucks. Especially over "washboard" type of roads or going over railroad tracks.- TechJK I had to replace my sway bar linkage.
use airchisel to remove bushing then threaded rod with two big, thick washer to compress bushing . take socket to drive bushing in with maul and used some bearing grease to assist in install , dropping passenger side control arm makes it easier. what knuckles
