I heard it referred to as Strut Rod Bushings at the Control Arm
I am having the same problem and it turns out to be that the bushing in the control arm to the frame is shot. The control arm is not suppose to move at all. This will also cause tire wear. You can actually replace the bushing at an inexpensive cost however, if you try to buy the bushing kit from the Saturn dealer, they will tell you that you have to replace the control arm. That is very expensive. By the way , you need a press to replace the bushing.
You must replace the entire control arm assembly with the ball joint included.
I find the best way to replace the radius arm bushings on that Bronco is to drill out the rivits that hold the backet to the frame and remove the bracket instead of trying to remove the radius arm from the axle. You can nut and bolt it back on. I would also soak the large nut and threads on the back of the radius arm with a good penetrating oil a few days before you tackle that project. That large nut can be a bear to get off without pneumatic tools.
U don't-the squeeking is from a worn out Bushing.
probably or there part of the same piece ....normally there's multiple bushings on a lower control arm ...i guess it just depends on the vehicle and its probably easier to replace the whole arm rather then individual bushings.
To replace radius arm bushings on a Mercedes A class, remove the 1 1/8 nut at the end of the radius arm. Cut the rivets out and remove the 4 bolts holding the hanger on. Remove the hanger and replace the bushings and bolt it back together.
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.
All you have to do is unbolt the nut off the back of the radius arm. Use a comealong and attach one end to the front framerail and the other to the hole in the radius arm, and pull the whole arm out of the bracket. After the arm is out of the mount, put on the new bushings. Use plenty of lube on the bushings. Always use poly bushings; they may squeek a little but they don't wear out. Then push on the end of the arm with your feet while a friend slowly releases the comealong. Put the rear bushing on the back of the arm and tighten the nut down with a big breaker bar.
