• Clunking or rattling from worn sway bar bushings
• Excess play in the stabilizer bar connection
• Uneven suspension feel caused by deteriorated rubber bushings
• Noise from a dry, cracked, or compressed bushing

Installation Notes and Tips

Verify the stabilizer bar diameter is 34 mm before ordering. Inspect the mounting surface and surrounding suspension components for wear, and replace damaged hardware or brackets separately if needed, since this kit does not include a bracket or grease fitting. Confirm the vehicle application by year, make, model, and front-to-frame position before installation.
