76 450SL how to:rear stabilizer link replacement
Hi all just replaced the rear stabilizer link assemblies. Purchased new ones off of ebay for under $30.00 for the pair. To do this repair remove the rear tires. One end of the link threads directly into the rear brake backing plate. The other end of the link uses the supplied lock nut to attach to the stabilizer bar. At first I believed I was going to have to remove the rear parking brake shoes to access the other end of the treads on the link to undo a possible lock nut. I presumed this because the replacement link part comes with a lock nut FOR EACH END. The lock nut that is on the end that treads into the backing plate IS NOT USED at least for this application. To be able to thread the link into the backing plate you will need to loosen the Stud/ball joint press fit in the socket of the new link by turning the link assembly's 17mm fixed nut. The press fit of the new part is tight so it wont finger rotate to screw it in easily if you dont loosen it up first. Now just start the stud into the brake backing plate by hand. Once it is just treaded into the backing plate hole continue to tighten the 17mm hex nut/stud/ball and socket assembly until it bottoms against the brake backing plate. Attach the other end to the stabilizer bar using the supplied lock nut and then go repeat the proceedure for the other side. I saw no info for this repair written anywhere to get instructions and even though it is a very easy repair, I had wrongly presumed more work was needed than was actually required because of the extra part (lock nut) that came with the new part. Hopefully this will save another person from removing a set of calipers and a brake rotor to inspect what is needed to get to a NON EXISTANT SECURING NUT that if present would be out of sight on the inside of the backing plate under the parking brake shoes. Removing these parking brake shoes and putting them back in place is no easy task and to do so for no reason would be enough to anger someone. Fortunately before removing those parking brake shoes, I decided to try to untread the old ball and stud that had separated from the old link's socket. It was still attached to that backing plate. As I said, I found it to be screwed directly into the threaded hole in the brake backing plate. No lock nut was utilized there. It would have been horible to have removed those difficult to work with parking brake shoes to look for a non existant hidden nut. I HAD unnecessarily removed the caliper and the rotor, this was work that was not needed at all to do this repair.
