Powerflex rear diff bush

Has anyone fitted one of these. I'm looking at the purple one for road use.

Are they a pain to fit?

Cheers

Its not complicated. Its straight forward but a lot of stuff to move around to get to it. You can approach it in different ways. Lowering and removing the entire subframe or lowering it and dropping one side.

There is a lot of info/pics spread throughout this thread.

Replacing the rear diff bushings is about as complicated as doing a clutch replacement. Ecs has pdf instructions for installing their dual mount plate. Check that out, it’s a lot more straightforward of a procedure than the TIS.

What about for a novice though. Was kinda hoping could do it in situ. Like take bolt out. Smash the bush and cup out slot home the new one . Guess not lol

Not possible, the bolts for the bushings are long enough that dropping the subframe isn’t negotiable.
