  • Single-rib design
  • Compatible with rear outer CV joint applications on select BMW models

Detailed Description

This GKN Loebro CV joint boot kit is engineered for professional repair of damaged outer CV boots. The boot material, shape, and dimensions matter because the wrong replacement can fail early or seal poorly. Part number 306420 is designed around the specified joint measurements and uses a solid rubber construction to restore protection around the CV joint.

GKN Loebro is part of GKN Automotive, a global driveline supplier known for OE-quality drive system components. This kit is intended for BMW 335i, BMW 335i xDrive, BMW 335is, BMW 135i, BMW 528i, BMW 335xi, and BMW 530i rear right outer and rear left outer applications listed in the fitment data. This part cross-references BMW 33207546049 for the same application.

What It Helps Fix

  • Torn CV boot material that exposes the joint
  • Grease loss from a leaking outer boot
  • Contamination entering the CV joint area
  • Noise or wear caused by a damaged boot seal
  • Boot failure from an incorrect material or fit

Installation Notes

Verify the joint end and shaft end dimensions before installation. Match the boot material to the original application, especially when the OE part uses TPE. Use the fitment data to confirm the correct BMW model, year, and rear outer position before service.

Quality Assurance
