Common Problems This Part Can Address

• Clicking or vibration from a worn rear CV axle
• Axle boot wear that can lead to grease loss and joint contamination
• Driveline noise during acceleration or load changes
• ABS signal issues when the tone ring or related axle components are worn
• Loss of smooth power transfer to the rear wheel

Installation Notes and Tips

Verify rear left fitment before ordering by matching the vehicle year, model, and axle configuration. Confirm axle nut thread size, hex size, and ABS tone ring requirements against the original part. Inspect the hub, differential flange, and surrounding seals before installation so the new axle can seat correctly and operate smoothly.

For best results, follow factory service procedures and torque specifications during installation. The bolt-on inboard joint design and included axle nut should be matched to the vehicle’s original hardware and mounting style.
