Hey guys,
Ok, my mechanic told me that my control arm bushings have leaked and need replacement. Honestly I haven't noticed a huge difference in ride quality or response, but I'd rather not keep worn parts on my car. He quoted my $500 to replace them, but I'm not sure if this is replacement of the entire control arm or just the bushings. Seems to me to be easier to replace the entire arm rather than try to press new bushings into the old ones? Also, is he referring to the upper (tension strut per BMW) or the lower (wishbone per BMW) control arms?

Anyway, I did a quick search here and got some good information, but one thing I didn't see: Are the control arms different for Sport vs non-sport suspensions? Also, are there some good non-BMW replacement arms that are recommended? I'd like to keep a decent ride quality, and I don't track the car.

Also, if I replace the arms, do I need a re-alignment? Seems that if the arms are exact replacement, then the alignment shouldn't be affected, but that's pure speculation on my part. Are the arms easily replaced as a DIY?

By the way, I have an E93 with Sport Suspension, if that makes a difference in your responses. Thanks in advance!

Just go with stock BMW parts. If you really want to you can go with the M3 control arms. They have a stronger bushing and are lighter, but they do increase NVH. Since you don't track it there's no real advantage other than longer life. If your shop has the proper tools they can replace the bushing and there are aftermarket solutions for just the bushings.

Good to know. So you answered one of my six questions, but I do appreciate the info.

I forgot to mention. The control arm is lower forward piece, the one that's oddly shaped. I don't believe that one requires a re-alignment after replacement even if you go with the M3 arms. Depending on your mileage you might want to get one anyway.

You can just press a new bushing into the tension strut. Meyle makes a HD bushing or you can get an oem replacement. You can also replace the whole link: oem, Meyle or M3. If you're riding on run flat tires, stick with oem or Meyle. If you're riding on traditional tires, get the Meyle HD bushings or you may like the reduction in tramlining and brake shimmy with the M3 tension links. Replacing the tension strut or bushing doesn't require an alignment.

The tension strut is the only oil fill bushing in the front suspension. The OEM control arms are $102 each from ECS, so if its not the whole arm being replaced you are getting screwed on that price. The bushings are only $45 from ECS for OEM parts.

Control arms are the same between sport and non.
Just go with OEM unless you want replace them again in 20k miles.

You should, but its not manditory but if you don't you might wear your front tires out sooner.
