Rear diff bush ??? Z3 1.9 16V 1998

[brittas]

I have just spotted a worn out rubber between rear axle can some one identity this please. Doesn't look that easy to replace.

Not replaced it myself but yes, Diff Bush and easily replaced. Lots replace with Poly Bush.

Great I will tackle that my self. I am sure there will be a guide on here somewhere.

Remove the arm from the car. Rip out the old rubber bush then using a hacksaw split the outer steel shell and remove that. Poly bushes come with fitting instructions.

I have old one out. Want to put bmw one in. Any chance of pushing bmw bush into diff in situation?

 

[brittas]

I may have to go powerflex bush if its too tricky to fit bmw one.

Would require specialised tooling, that's why people fit the poly type bushes.

I’ve photos on this and my diff oil change, remember? Just didn’t take any notes so can’t do a How To guide.

Agree - Special tools required referred to in this https://www.newtis.info/tisv2/a/en/...3-17-rear-axle-differential-mountings/ANLDVWQ

There is a very simple tool that costs around £1.

The downside is that you need to remove the casing cover.

I have ordered powerflex bush so It should be pretty easy.

Both mine replaced with power-flex poly-bush, very easy, but be advised you MAY experience a little more transmission noise with the poly-bush, but its negligible.

A point to note, I used washers as shims to avoid the "ears" from bending when torquing the bolt.

Good to have both of those links as I want to give it a go with a stock bush. Jonco's as now I know how BMW do it and I won't be buying one of those tools! And Pingu's as hopefully I can make my own tool now and I have a 10 ton press so hopefully that will help.

The part number on my link is for the M Roadster bush. I think that it is different to standard. Just check RealOEM.

I used a vice to squeeze the bush into the cover. A 10-ton press should be much easier.

i changed the rear diff gasket at the same time i did mine dead easy... and of course put fresh oil in the same time...
