Suspension Replacement question

DaveSakky135 · 01-20-2013, 02:27 PM

My 135 is about to hit 100k. The suspension doesn't feel to bad, but i have been noticing some excessive noise over bumps sometimes like a clanking from the front.

My question is what parts should be replaced around this amount of miles? I have a set of shocks and struts as well as a front sway bar from my first 1er that i crashed with 30k miles on them. Should i just throw those one?

Thanks

The noise could originate from a number of things:
-Leaking control arms
-Loose bushings
-Worn shock mounts
-Sway bar end-links
-...

Your best bet is to have the car professionally inspected at an indy shop.

so it looks like its more the control arms than the shocks and struts

Worn out dampers will make noises too; I wouldn't count anything out. Between the dampers and the control arms, I think it's more likely the control arms would wear out first though. I've seen them go with well under 100k miles.

Your best bet it to have a mechanic look over your bushings and see what if any need replacing. If all the bushings look good then it might be the shocks.
