The bushings in the links are vulcanized in place are are actually part of the spring, the steel center is bolted down hard, doesn't move. The bushing at the spring link (aka lower control arm) is easy to replace, but you must remove the spring.

This isn't a terribly hard job, but I would need to know what needed fixing before being too specific. The links are a pain -- there is one LONG bolt one must back a locker nut off one flat at a time due to lack of clearance, and on some models this is an eccentric screw, so you MUST turn the nut. New links require new bolts as they are actually from the 210 chassis, I believe, and different bolts are used with them. Otherwise only time consuming.

Locate the squeak (it could be a shock, too!) and examine the rubber in the links in the rear. Distortion, torn rubber, or "shedding" of rubber in strings are a sign they need replacement.

At least one supplier sells a "kit" -- torque, thrust, camber, and tie rod links plus bolts, last price I heard was around $250. Probably worth it to do all of the, followed by a four wheel alignment. For the effort, I'd personally probably do new spring seats and spring link bushings and have a new rear suspension.

Note that there are also four subframe mounts and four differential mounts, probably need those, too.
