If the CV joint malfunctions, it will affect the car maneuvering. Therefore, the greasing is necessary as it prevents premature wear by water or other contaminants. It is also necessary to grease a CV joint during its rebuilding processes, like replacing a CV joint or replacing an axle stub.

What kind of grease for CV joints is the most suitable? The most suitable type of grease for CV joints is lithium grease. It is a heavy-duty, premium quality grease that contains molybdenum disulfide and graphite.

Open the boot by unbolting the cover or removing the big clamp. Then, get rid of the old lubricant by scooping or draining. In the case of a dry joint, move it to clean and apply new grease on it.

Finally, clamp the boot. For a wet axle, apply one pack of lubricant before installing a new clamp.

Greasing Method for Torn Boot

For performing this task, you need to have a CV boot kit. There are several kinds of kits available in the market. Some of these contain enough components for both inner and outer boot.

After opening the boot, disassemble and clean the axle. For cleaning, the car part washer is the best. However, using some degreaser and a brush will work as its alternative to remove all grease residue.

After that, rinse and air dry the components before reassembling. Before the big clamp installation, apply grease and distribute it evenly by hands.


Things to Remember about Greasing CV Axle
