The top fastening of the suspension strut is attached to the chassis via the strut mount – also known as the suspension strut mount. Since the strut mount must have both a damping force and a rotatable mounting for unhindered steering resetting, there are strict requirements for its function and wear resistance. Checking the strut mounts on a regular basis will ensure the vehicle is safe.
A worn or defective strut mount can be recognized by various symptoms. These include:
• Squeaking during spring movements of the chassis
• Poor cornering
• Crackling noises during steering wheel movements
• Restricted resetting of the steering after cornering
• Knocking sounds when driving over uneven surfaces
If the suspension strut mount has been checked and a defect has been detected it should be replaced as described below. Like other chassis components, suspension strut mounts should always be replaced in pairs.
