Detailed Description

Common Problems This Part Can Help Address

• Torn or cracked steering rack bellows
• Contamination entering the rack and pinion assembly
• Loss of protection around the inner tie rod area
• Noise or wear caused by damaged steering boot material
• Failed inspection due to a visibly deteriorated bellows boot

Installation Notes and Tips

Verify side-specific fitment before ordering, since this part is listed for both left and right positions depending on vehicle and model year. Confirm the steering rack dimensions and attachment style against the original bellows before installation. Clean the rack housing and inspect the inner tie rod area for wear, leaks, or damage before fitting the new boot. For best results, install the clamps securely and ensure the bellows is seated evenly at both mounting points.
