Mercedes Differential Side Cover Seal - Elring 0039978347

Product Information

A CV joint boot serves to protect the axle joint and axle by keeping out dirt, water, and debris while preserving the grease that lubricates the joint. As a vital component of the drivetrain system, it enables the wheels to move in coordination with the vehicle’s suspension. Regular inspection of CV boots is essential, and they should be replaced before any signs of failure appear. Replacing a boot typically involves removing the old one, reapplying grease, and fitting a new boot, which will require tools for expanding the boot over the joint as well as clamping a special style clamp on both ends to prevent exposure. At the point of service, it is also recommended to expect the condition of the joint, if the joint is damaged, a full joint replacement may be necessary.

• NVH: Clicking or popping sounds when turning or under load caused by binding in the joint during articulation
• Leakage: Grease splattered on or around the inward-facing side of a wheel and/or suspension components behind the spindle
• Drone: Humming or growling noises coming from a dry joint or a joint exposed to the elements
