Recommended service: Replace when installing new front struts
High-mileage BMW vehicles may require replacement of the front struts and upper strut mounts. The upper mount houses the strut bearing, which can develop play, binding, or a rough, crunchy feel as it wears. Replacing both mounts during front strut installation helps restore proper steering movement and prevents premature wear of the new suspension components.
Suspension Strut Mount
Strut mounts are common wear components on vehicles equipped with MacPherson strut suspension. They secure the top of the strut assembly to the chassis while allowing the assembly to pivot as the vehicle is steered. Over time, the bearing can wear or bind, and the mount's rubber isolator can crack or deteriorate, resulting in noise, looseness, vibration, and reduced steering performance.
For optimal suspension performance and service life, both front strut mounts should be replaced whenever new front struts or complete strut assemblies are installed.
Suspension Strut Mount Failure Symptoms
Clunking or knocking noises: Worn mounts may produce noise when driving over bumps or rough roads.
Excessive vibration: Cracked or deteriorated rubber can transfer additional vibration through the steering wheel or chassis.
Poor steering response: A worn or binding bearing can make steering feel rough, heavy, or less responsive.
Uneven tire wear: Excessive mount movement can affect suspension geometry and contribute to irregular or premature tire wear.
Increased body roll or sway: Worn mounts can reduce suspension stability and allow greater body movement during cornering.
