CV Boots & Axles

The Constant Velocity boot or the CV boot is the rubber casing that you can find covering your CV joint at the CV axle of your car. They are all part of the shaft assemblies used in front-wheel-drive and four-wheel-drive vehicles. The shaft assemblies supply torque to the wheels while they are turning and to the suspension while it is moving up and down.

The CV boot protects both the inner and outer portions of the CV joint and keeps away water, pebbles, and other road dirt from entering into and damaging it. The inner CV joint controls changes in suspension and ride height, while the outer one provides even torque transfer.

So when the boot is ripped or cracked, the lubricant inside it could spread and mix with the dirt, damage the joint even more, and affect steering and suspension. Damage to the CV boot leads to damage to the CV joint, sooner or later.


It is therefore wise to attend to the littlest sign of defect in the CV boot immediately. Doing so could save you money because the CV joint is much more expensive to replace. You will know that something is wrong with your CV boot when you hear of a clicking sound while your wheels are turning and feel a shudder while you are accelerating or decelerating.

 
Axles
Is your vehicle beginning to make those grinding and jarring noises when shifting gears? Your axle assembly might have a problem. This is most prevalent to vehicles that travel difficult terrain for the road. It can give much stress to an axle assembly. The road's bumps, turns and potholes and immoderate shifting can really damage a drivetrain, especially its component parts. The axle shaft can give much stress to the CV-joint (constant velocity) or even a U-joint if not properly handled. The gear transfer should be seamless. This could be done if the parts are meticulously greased and are protected from outside elements like dirt.

Certain Steps must always be followed to make sure that your drivetrain assembly is always working fine. The boot or the rubber gasket that protects a CV-joint from dirt and other elements should always be inspected for leaks. Contamination inside the axle assembly can cause much damage for the joints. A small amount of contaminants can really destroy your axle assembly's joints.
