FAQs

What is a CV Joint Boot?

A CV Joint Boot is a flexible rubber or thermoplastic cover that protects the Constant Velocity (CV) joint on a vehicle's drive axle from dirt, debris, and moisture, while also retaining lubricating grease.

What is included in the Febi Bilstein 31688 kit?

The kit includes a thermoplastic bellows (boot) for the drive shaft, molybdenum grease for lubrication, and two clamping clips for securing the boot.

Can I use this boot on the rear axle?

No, this specific part number (31688) is designed for the front axle applications only.

How do I know if my CV Joint Boot needs replacement?

Signs include clicking or popping noises when turning, visible tears or cracks in the boot, or grease splatter around the wheel area.

What are the main dimensions of this boot?

The bellows have an inner diameter of 24 mm and 78 mm, and an outer diameter of 117 mm.

Is molybdenum grease better than standard grease for CV joints?

Molybdenum grease is specifically formulated for high-pressure and high-temperature applications like CV joints, providing superior lubrication and wear protection compared to general-purpose greases.

What is the weight of this kit?

The total weight of the kit is approximately 0.15 kg.

Troubleshooting

Boot appears loose after installation

Ensure the clamping clips are securely tightened around the boot at both ends. Verify the correct boot size was used for the application.

Excessive noise from the drive axle after installation

Check that the correct type and amount of grease were used and that the boot is not torn. Insufficient lubrication or incorrect installation can lead to noise.

Clamping clips won't secure the boot

Ensure the boot is seated correctly against the shaft and the groove. Use the provided clips or equivalent heavy-duty CV boot clamps if necessary.

Setup, Compatibility & Care

Compatibility: This CV Joint Boot kit is designed for the front axle, fitting on the left, right, and wheel side. Always confirm that part number 31688 is the correct replacement for your specific vehicle make, model, and year before installation. Check the inner (24mm/78mm) and outer (117mm) diameter specifications against your existing boot.

Setup: Installation involves removing the wheel, potentially disconnecting suspension components or the drive shaft, removing the old boot, cleaning the CV joint thoroughly, applying the provided molybdenum grease, fitting the new thermoplastic bellows, and securing it with the included clamping clips. It is highly recommended to have this part installed by a qualified mechanic if you are not experienced with drive axle repairs.

Care: Once installed, the CV joint boot requires minimal direct care. Regular visual inspections during routine maintenance are advised to check for any signs of damage, such as tears, cracks, or signs of grease leakage. Clean any debris that may accumulate around the boot during regular vehicle washing.
