Why E34 rearends are loose

[BigKriss]

Winfred and Bill R have both told me the trailing arm bushes almost never wear out. I have yet to fit my subframe bushes with liquid urethane. I don't know what rear swaybar your running Robert, maybe you can fit a larger one to get the rear of the car firmer. As for profane language, I'm young and dumb. I don't mind it.

I actually bought the Racing Dynamics sway bars shortly after purchasing the car. I've always been a fan of fitting the biggest sway bars possible to my cars. I'll give up a bit of ride to increase the responsiveness of the quicker turnin any day. I've also got the M Technic spring package on mine with stock Boge gas struts. On top of that, I've got 17" Style 5 wheels with Bridgestone Turanza LSZ's. The ride is firm, but certainly not punishing.

Grace and peace,

If you put a smaller sway bar on the front of the car, and a stiffer one on the rear, you will tighten up your rear end feel in turns.


Also, check out this tutorial about adding a plate underneath the bushing to stiffen things up:

No prafanity? No wonder it's not fixed! lol
I agree with you, that was a great writeup & I'm saving it because my rear is loose as well. You probably saved me a hell, I mean, a heck of a lot of work trying to find the problem.
Thank you

correct me if i'm wrong, but this is what we're (or, everyone else, rather. while i eavesdrop) talking about right?

also, great thread, lotsa info. and another thing, you're absolutely right about the profanity. unfortunately, i'm one of those guilty, and there's no excuse for it. other than i'm usually pretty upset when i do it. which is probably worse.
