What It Helps Fix

• Rear suspension clunking from a worn axle support bushing
• Excessive movement at the rear lower axle mount
• Rubber cracking, splitting, or deterioration
• Loose or unstable rear suspension feel
• Noise caused by bushing wear in GM rear lower applications

Installation Notes and Tips

Verify the rear lower position and confirm the 48mm bar diameter before ordering. Because MK6288 uses a press-in attachment method, proper bushing removal and installation tools are recommended for service. Inspect the surrounding suspension components and mounting surfaces for wear before installing the new bushing.

Quality Assurance

Mevotech supplies chassis and suspension service parts for OE-style replacement applications. Confirm fitment by year, make, model, position, and bar diameter before installation.
