I picked up a set of Powerflex Rear Diff Bushing Inserts (PFR5-1826) a while back. They didn't come with any instructions and in my excitement to install them I put them in with much haste without spending a lot of time on it. I noted from time to time that I'd get a clunk from the back when pulling out of my driveway. Today I had some time so I re-examined my work, guess what, I installed them wrong.

So since there aren't any instructions I figured I'd write some. See attached photo for correct vs incorrect examples.

Do one side at a time. On the drivers side you may need to remove the exhaust hanger in order to lower the exhaust enough to pull the diff arm down, its held to the car by two 13mm nuts.

1) Remove the 16mm bolt
2) Spray the inserts with your favorite lube
3) Pull the arm down and install bushing from the top side.
4) Reassemble

 

What does this do for the R60? Worthwhile mod?

 

Yeah, I liked it. I had these and the lower engine mount insert. The rear didn't make as big of an improvement as the engine one did but it was noticeable.

What it does is reduces the mount of movement the rear diff can make when under load. Means more power to the ground faster.

 

Thanks for taking the time to post this...really appreciate it. I just ordered a pair to complement the front engine mount bushing.

 

Huge thank you for posting this!
