BMW Suspension Control Arm Bolt - Genuine BMW 31306779823

Product Information

Although your vehicle's suspension relies heavily on the the various links, arms, bushings, and joints that make up the average suspension system, it is also equally important to inspect and replace the miscellaneous hardware in the suspension. Many cars will use key bolts, washer and nuts, to attach these arms and adjust alignment features like camber and toe. Some makes will incorporate cammed bolts and washers that position the link or arm in the suspension closer to, or further from, the chassis thus altering alignment settings. It is also equally important to make sure you are using the correct hardware attributed to your vehicle's suspension and understand when and why certain components are to be used.

As this hardware has such an impact on the suspension and the alignment parameters, they are commonly misdiagnosed as being a faulty part as opposed to faulty hardware. Below are things to look for for diagnosing faulty suspension hardware:

• Poor handling after suspension work or overhaul, and the inability to hold alignment settings
• Uneven tire wear, even after being properly aligned
• Excessive suspension noise
• Loose links and arms in the suspension
