URO Differential Cover for E46 M3

Product Details

By 100,000 miles, the BMW E46 commonly experiences rear differential bushing failure, a known weak point in the chassis. Unlike non-M models, the E46 M3 lacks a factory-style serviceable rear differential bushing, meaning failure necessitates replacing the entire rear cover—an expensive and labor-intensive process. Instead of swapping out the entire cover, a cost-effective and performance-driven solution is upgrading to high-quality ECS polyurethane performance bushings , engineered to enhance durability, reduce drivetrain deflection, and improve power transfer (T#348998). Available at Turner Motorsport , these premium bushings provide a long-lasting alternative to OEM replacements while maintaining a factory-like ride quality.
