Wandering Rear End? - Rear Trailing Arm Bushes

[Anonymous]

I didn't attempt this job myself because I have heard that the OE bushes can be a pig to get out of the trailing arm.

When searching around I saw some people using a special pulling tool to remove them.

Sometimes the trailing arm has to have a fair bit of heat on it before they will shift. I watched the bloke who did mine at Elite and he had to put what I consider a lot of heat on the trailing arm before the bushes would start to move.

Just so people are aware before tackling this job on the driveway.

Questions though - this drilling that has to happen I assume the cage does not have those fitting holes in it to start with ? And if I'm doing this then replace the bushes too whilst I'm there because they'll probably be shot ? And finally, why did you guys choose the TMS kit over the (simpler to install) Rogue Engineering kit - because the RE kit is poly and could squeak ?

Bing, when I fitted the limiter kit my car had done around 25k miles at the time and the RTA bushes looked in excellent condition, so the original OEM bushes remain in place. I fitted the TMS limiters because, it was the only kit I knew about at the time and didn't want to fit polybushes from my past experiences of these things as "moving parts". If I'd known of the Rogue limiters, then I would most likely have opted to fit those, as an easier job and cheaper product. I doubt if the Rogue limiters will squeak because there will only be lateral pressure on them and not rotational forces. The squeaking I experienced was only noticeable on relatively slow manoeuvring which made the car sound like an old wreck, and when the car was being pushed my attention was focussed on other things.

There's no chance of removing OEM rubber bushes without a puller and aided by a bit of lubrication. When I did the job on my Z3MC I made a puller as in the photo. You can buy/hire something similar if you need to remove and install bushes. Swapping bushes is NOT an easy DIY job.

@Exdos - that's excellent news as mine is on about 25k too and I know it's not been abused...so the bushes should be ok. Given what you've said I think I'll go for the RE option in the first instance

Unless your replacing the bush we don't need to remove it from the trailing arm to add the limiters .

So some interesting information today. My car is currently at Center Gravity having various suspension changes done and it transpires that my car (which is really quite harsh and makes lots of VERY annoying suspension noises) currently has black poly bushes. These are being changed to OEM bushes with the Vorschlag limiter kit.

Looking forward to getting it back and seeing what the difference is like.

Tertius, I hope you've got your car back by now; how does it feel since the change to OEM + RTAB limiter kit?

I realise mine is not an //M, but I am experiencing similar traits with a car that tends to be quite wandery, particularly at speed, and was looking at the RE or Vorschlag limiter kits as a cheap mod to try and reduce/eliminate this...
