What It Helps Address

• Vibration or shudder under acceleration from axle wear
• Grease leakage from a damaged axle boot or joint seal
• Driveline noise caused by excessive joint play
• Uneven power transfer at the front right wheel

Installation Notes and Tips

Verify the vehicle’s chassis breakpoints and suspension configuration before ordering, especially for 2016 GLA250 and 2017-2019 GLA250 models with notes such as “without high ground clearance.” Confirm the front right position, axle length, and spline counts against the removed part before installation. Inspect the hub, transmission seal area, and mounting surfaces for wear or damage, and replace any compromised hardware or seals as needed during service.
