Default Re: DIY: front control arm balljoints

I changed ball joints on a set of 98 328i control arms. Used a hydraulic press and they popped out hard. Make sure your foot or shin is not in the area. For my 99M3, I bought new BMW arms during a cheap sale -- about $140 each.

On my other cars, I am getting less interested in pressing bushings. I changed lower control arm front bushings on my 08M3 and it was a pain. I bought TRW replacement arms for the upper control arms. For my 08 535xit, I bought the whole lower control arms rather than press bushings and ball joints. I am at the point in my life where easier is appreciated even if it costs a bit more. I still save money by doing my own work.

Default Re: DIY: front control arm balljoints

I just got done replacing the ball joints on my '99 m3. For some reason, probably cost, the control arms had been replaced in the past with non-m arms. They had the correct number of holes in them but had the rubber isolating outside ball joints. One arm was bent so I replaced it with Meyle HD control arm for a e36 non-m. The other arm was good so replaced the ball joints. I used the Meyle HD solid metal joint since the arm had the larger rubber isolating one. Then I also replaced the bushings with the '95 m3 offset bushings to have the correct caster.

There are some forms around about this, but bimmerworld was who confirmed that this setup is technically sound.

Now time to go get it aligned.

The geometry on the non M arms for post 96 cars is wrong. Your caster will be decreased.

But he is converting with both the non-M arms and the 95 M3 offset FCAB. Isn't that the same as going to the 95M3 geometry? Or does he also need to change the strut mounts?

Additionally, the 1996+M3 CAs contribute to addition wheel camber at full steering lock.


The Spindles/King Pin, FL Control Arm, centered FLCA Bushing, and Bearing Plate/Guide Support geometry all changed for 1996+ M3 front suspension, not to mention upper spring diameter change (stiffer) and matching Spring 'Hat', and strut p/n (valving?).

1995M3 offset FLCA Bushing is not an 'upgrade' for the 1996+M3s.

I corrected the caster by using the offset FCA bushings.

Thanks for the reply and details. When I look up the part number for the knuckles for '95 and '96+ they have the same part number, so it seems that they didn't change. I'm not sure about the springs but that shouldn't really affect the alignment dimensions would it?

I didn't do this to be an overall upgrade and I agree it isn't. I did this as a cost effective solution with what I got from the PO. The part that is upgrade from what I have are the outer ball joints are solid metal instead of the rubber isolated ones from the non-m cars.

Sorry about my IMGUR hosting being complete garbage. I have uploaded the pictures to somewhere else and fixed the links in the OP.

How timely!! I was just looking at this write-up hoping to see images.

Did you mention purchasing tubes to facilitate pressing these BJs?
