Detailed Description

GKN Automotive supplies OE-level driveline components used by major vehicle manufacturers worldwide, and this GKN Loebro 305997 CV axle assembly reflects that application-specific approach. It is built for rear right fitment on 2013-2018 BMW X3 and BMW X4 models, including 2017 BMW X3 rear right applications with a 28mm diameter axle note and 2017 BMW X4 rear right applications with a 28mm fitment note. This part cross-references Monroe Shocks & Struts 33207598038 for the same application.

Use this axle assembly when the original BMW X3 or BMW X4 rear right shaft shows wear at the CV joints, spline interfaces, or axle nut connection. The plunging joint design at both ends supports driveline articulation while maintaining the correct OE-style geometry for the vehicle platform.

What It Helps Solve

• Clicking or popping from worn CV joints during acceleration or turning
• Vibration caused by worn axle splines or joint wear
• Grease leakage from a damaged axle assembly
• Driveline noise from a failing rear right axle shaft
• Fitment issues when replacing a BMW X3 or BMW X4 rear right CV axle

Installation Notes and Tips

Verify rear right position, spline counts, compressed length, and axle nut thread size before installation. Confirm the 28mm diameter note on 2017 BMW X3 and 2017 BMW X4 applications where listed. Inspect mating hubs, seals, and related suspension components during service, and torque fasteners to BMW specifications.
