Detailed Description

This CV joint boot kit is engineered for front outer axle service where the original Volvo boot has torn, slipped, or become porous. GKN Loebro 303420 uses TPE material, which is commonly specified for factory driveline protection because it handles elevated operating temperatures and helps maintain a secure seal around the joint. If your original driveshaft uses a TPE boot, matching the replacement material is important for proper service life and fit.

This part cross-references 272440 and 31256231 for the same application. It is a practical replacement for Volvo front outer CV boot service on 2001-2007 Volvo V70, 2003-2007 Volvo XC70, 1999-2006 Volvo S80, 1999-2004 Volvo C70, and 1999-2000 Volvo S70 applications. The part number 303420 is also useful when searching for an OE-style Volvo CV joint boot kit by exact application.

What It Helps Repair

• Torn CV boot causing grease loss
• Slipped boot that no longer seals the joint
• Porous boot material that allows contamination
• Noise or vibration related to joint contamination
• Premature CV joint wear from loss of lubrication

Installation Notes and Tips

Verify the original boot material and joint dimensions before ordering. This kit is intended for front outer positions only and should be matched to the specific Volvo transmission and chassis notes listed for the vehicle. Clean the joint thoroughly during service, inspect for wear or contamination, and confirm the boot seats correctly before tightening the retaining hardware.

For best results, replace the boot as soon as damage is found. A damaged boot can quickly lead to grease loss and joint contamination, especially on AWD Volvo driveline applications.

Quality Assurance

GKN Automotive supplies OE-quality driveline components and designs this boot kit to meet the fit and material requirements of factory-style CV joint service. The TPE construction is selected for the thermal demands of modern driveline systems and for use where the original shaft was equipped with a matching TPE boot.
