OE-Quality CV Boot Kit for BMW Axles

GKN Loebro 304013 is a premium OE-quality CV joint boot kit for front outer axle applications. It is built for exact fit and the correct material selection, which matters when replacing a torn, slipped, or porous boot on BMW driveline components.

Compatible with select BMW X5, 325xi, and 330xi front outer positions, this GKN Loebro CV boot kit is designed to match the joint application rather than using a generic universal boot. The black rubber solid boot construction supports a precise repair on the original driveshaft assembly.

Detailed Description

GKN Loebro 304013 is engineered for BMW front outer CV joint service where exact fit is critical. The boot is the sealing component that keeps grease in and contaminants out, helping preserve the joint’s operating condition. This replacement boot kit is intended for applications where the original boot has failed due to cracking, tearing, slipping, or material breakdown.

This part cross-references 31607507402 for the same application. It fits 2000-2006 BMW X5, front right outer and front left outer, with version “A” notes for the specified production window; it also fits 2001-2005 BMW 325xi and 2001-2005 BMW 330xi in front right outer and front left outer positions. For BMW X5 applications, verify the production note and version detail before ordering. The part number 304013 is the reference to use when matching the correct boot kit for these driveline repairs.

Common Repair Uses

  • Replacing a torn CV boot on a BMW X5 front outer axle
  • Repairing grease loss caused by a cracked or porous boot
  • Restoring protection after a slipped boot on a 325xi or 330xi front axle
  • Addressing contamination from road debris, water, and dirt entering the CV joint
  • Servicing a worn outer boot before the joint itself is damaged

Installation Notes and Tips

Confirm the joint end and shaft end dimensions before installation, and match the boot material to the original application. If the original driveshaft uses a TPE boot, GKN Automotive recommends selecting the matching TPE replacement boot kit rather than substituting a different material. Clean the joint thoroughly before assembly, inspect the axle for wear, and verify the BMW X5 version and production date notes for the front outer position. The kit includes the individual repair components needed for professional service.

Quality Assurance

GKN Loebro is part of a global driveline systems leader known for OE-quality replacement components. This boot kit is built to the same application-specific standards expected for precise BMW driveline repair, with material and fit selected to support reliable sealing performance.
