BMW and MINI Front Suspension Noise, Popping, Cracking When Turning
This answer is applicable for many BMWs in addition to the one listed below.
Model: BMW E34 525i
Otto! First and foremost just want to thank you guys for the great service you have given the BMW community in the past years. I have always purchased all my parts from Bavarian. My name is Alex I own a 95 525i my only question is. I’ve noticed lately that when I am turning at tight corners or doing a U-turn I hear a cracking sound…as I am turning. Would you be able to assist me on this. I would like to get this repaired.
The sound that you’re hearing when you turn may be due to one, or more, of the following issues:
* Wear in any of the front suspension joints, such as:
* Control arm ball joints
* Tie-rod end joints
* Center track rod joints
* Swaybar end links
* Upper strut mounts
You could also have a less common issue such as cracked (or loose) steering gearbox mounting points, or other chassis issues. We would suggest that you have a helper operate the steering while you stand outside the car and work on localising where the sound is coming from. This would be a great help is narrowing things down.

* Control arms & ball joints:
* Center track rods:
* Sway bar end links:
* Upper strut/shock mounts:
We can consider either a full overhaul of the front suspension or you will need to do some inspection of the above noted items. See the Winter 08-09, Spring 2009 and Summer 2009 issues of our Fast Times newsletter for a series of articles on vehicle inspection, as well as control arms and bushings replacement (on a 3-series chassis). Once we have a better idea of what may be at fault, we can get to ordering and replacing the required items. We do keep all of this in-stock.
