Over the years, the road takes a serious toll on your suspension. Pot holes, speed bumps, and road hazards all contribute to a sloppy, weak suspension. To give a better feel to your driving experience, change components as they wear to improve safety and ride comfort.

One item to replace is the control arm. After years of service, the non-serviceable ball joints and other components can begin to wear out. Because some components cannot be replaced, the only solution is replacement of the entire arm.

If replacing any part of your front or rear suspension, it is best to either do it in pairs (both left and right sides), or examine parts that are prone to failure. This will provide the most service life out of replacement parts and assure they are all performing properly.

Referred to as a wishbone by BMW.

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over.

If the control arm bushings on your vehicle are beginning to fail, it will become quickly apparent. Suspension noise will be drastically increased, there will be steering wheel shake when hitting road hazards, and the entire car will have an all around loose feel. This can also lead to premature tire failure as alignment is negatively affected. Replace your control arm bushings to give your entire suspension a tighter feel.
