► There are several methods out there which show how to do this procedure. One of the more popular procedures I have seen involves clamping the swing arm underneath the wheel carrier with a vice grip. I do not prefer this method because I believe it puts too much tension on the swing arm (lower control arm) bushings and you also run the risk of marring the surface of the control arm with the vice grips.
Either way, I am not interested in damaging a near $400 control arm. I opted to lower the swing arm by removing the eccentrics after carefully marking my alignment. This got the swing arm out of the way and allowed me more access to the ball joint. If you use the BMW special tool this won’t be an issue. However, if you rent the universal c-clamp style tool the swing arm will undoubtedly get in the way. Bottom line is I recommend lowering the arm out of the way for easier access.
The snap ring which holds the ball joint in the bore will likely be corroded in place. You will need to work at this for awhile to break it free. Using a fine flat head screw driver and a hammer you should be able to get under the backside of the snap ring. Work your way around the entire ring until it releases. The ring will be bent out of shape but that’s fine because it needs to be replaced anyway and most new ball joints come with a snap ring. When pressing the ball joint out you may notice it “pops” when it releases from the bore. When installing the new ball joint make sure to clean the bore with some sandpaper first to clean up any corrosion. When pressing the new ball joint in make sure it is going in straight. For the most part the ball joint will center itself and press all the way through. Make sure you replace the 24mm self-locking nut with a new one.
When it comes time to tighten all the fasteners to spec make sure it is done at ride height This can be accomplished by using a floor jack to lift the suspension while still supported by jack stands (or by a lift in our case). Failure to torque at ride height can cause premature component wear as well as inaccurate torquing.
Torque specs:
Integral link bolt (Integral link to wheel carrier) - 77 ft-lbs
Self locking hex nut (For swing arm bolt) - 189 ft-lbs
Nut for swing arm eccentrics - 43 ft-lbs
Note: that this repair will also be similar on E38, E53, E60, and E90 models
