BMW Suspension Parts for BMW 3 Series E91 (2006-2012)

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components.

The strut mount is a critical suspension component that provides a secure mounting point and pivot for your BMW's front strut. With higher mileage, the built-in bearing can wear out, leading to reduced suspension performance, increased noise, and compromised handling.

For optimal suspension function and durability, it’s recommended to replace the strut mounts whenever installing new front struts. Choose this premium replacement from Bremmen Parts for a reliable and long-lasting repair.

The rear bump stop support cup is an essential part of your suspension system, positioned at the top of the rear bump stops to provide a stable mounting point and ensure optimal suspension functionality.

With prolonged use and exposure to demanding driving conditions, these support cups can experience wear or damage, which may compromise suspension performance and overall ride quality. Replacing worn support cups helps maintain the reliability and effectiveness of your suspension system.
