E34 rear subframe bushing puller near Seattle?

Post by Martin in BellevueWA »

Anyone have the tool to pull the beer can bushings? Going with Condor Speed split poly bushings.
Torching rubber & chiseling the sleeve isn't my preferred way to do things.

No help on the tool, but... If they're like E28 bushings, the sawzall method is far more refined than the torch method, even if a bit crude compared to the correct puller tool. I was almost disappointed with the lack of difficulty on my E28. If they're like E39 touring bushings and stepped, good luck, you absolutely need the correct tool.

The correct tool would've been good. I got the 2nd old bushing out; it also sucked.
The new bushings corrected a vagueness in tracking. The new bushings also magnify (not too much) a drone from the ttv 14lb flywheel between 1,400 - 1,800 rpm.

These UHMW bushings suck. I put some cork (cut from sheet) above the bushings, which reduced much of the noise, but not enough.
Now looking at stock Lemforder bushings, the softest 2 piece poly bushings; AKG medium poly-85a and 80a revshift bushings.

UHMW is a super hard plastic. I went with powerflex yellows and noticed no NVH penalty.

if you insist on poly (no judgement, i totally understand for the ease of installation aspect), i would recommend Powerflex. i used AKG bushings for many years, but after a few bad batches of them, i won't anymore.

that being said, if you have access to the tool for reinstalling the OE replacement bushing, i would highly recommend that. :)

I have the revshift 80a revshift bushings coming from turner, just in case the Lemforder bushings are crap.
It is a sad day that we gotta question Lemforder quality.

Thanks for the replies & PM's.

UHMWP is great stuff, tough and slick, but I can't imagine using it in place of rubber.

I'll second this. I used powerflex yellows and there was no noticeable increase in NVH compared to the lemforder ones I used in my other e28.

The revshift 80a bushings are quiet and fit well. The upper half is better contoured. I like the softer revshift bushings.

OK cool that is my exact question I was going to post but didn't want to wake a zombie LOL. Powerflex was my presumption and thanks for verifying it.

Fortunately for me my local dork Spen (board member) has a subframe at home we will just prep and replace, easy-peasy. Rear Billies are still solid but a bit leaky. We did the front Billies a few months ago and the dog bones and a driveshaft too so things are pretty well sorted. Your basic 185K shakedown. Interestingly the front end feels solid even though there are no bushings or anything in the receipt book. Whatever the case I'm still gonna wait for it.
