Differential bushes
Discussion
The diff bushes on my '96 Chimaera 500 are worn and I believe need replacing.
Can anyone advise whether this is a suitable DIY job for someone handy with a couple of spanners, or do I need to take it to the professionals?
Also I believe there's a choice between rubber or poly bushes. Presumably neither are very expensive, but can anyone advise on the merits of each? I think I've heard that poly bushes wear better, but may transmit more transmission noise into the cab.
Thanks

I replaced the side bushes and the rear bracket myself. Both relatively easy to do, just a bit of a pig mauling the diff around getting to the rear bracket.
My side bracket bolts had loosened off which had elongated the bolt holes, hence all the movement.
Make sure you push the bushes out the right way too, they have a lip on the one edge! I made a tool and compressed them in a fly press.
Wouldn't like to replace the rear bush tho, looks extremely difficult to reach!
Hope this helps.

Mine started with a dull clunk from the diff area when lifting off the throttle. Also noticed the exhaust was grounding easy.... This was due in fact to the rear bracket failing and tearing apart! This had caused the diff to drop in the chassis and push down on the exhaust!
The design of locating the diff seems far from ideal in my opinion and relies heavily on the tightness of the bolts on the side mountings. These bolts pass thro clearance holes only on the brackets, are then threaded into the diff casting with nuts on the end. It is imperative that the bracket grips against the diff otherwise it will "float" between the nut and bolt head.
By the way, my car is '96 with aluminium cooling fins on the back, can't remember which type this is, sorry!

My symptons are identical. I've been driving very gently over the last few miles, so as not to rip the transmission apart. Somewhat takes the fun out of it if you can accelerate hard, but saves a bit of go-go juice (not that fuel consumption is an issue for tivvers).
The other clue was that I was told at the last service that they were worn and would need doing.
