Axles

The functions of an axle.

Axles are an integral component of your vehicle. An axle is a central shaft for a rotating wheel or gear. The axle transfers power from the vehicle’s powertrain to the wheels. In a front-wheel drive transmission, the gimbals (short shaft) move the front wheels. In a rear-wheel drive transmission, the central shaft channels power to the rear wheels, and in an all-wheel drive transmission, the transfer case directs power to all four wheels.

In order to handle all the hazards of the road, axles and gimbals are connected by swivel joints, several of which are coated with grease and protected by rubber boots.

What are the signs indicating a faulty axle?

Your axles are the last link in transferring power from the engine to the wheels. Axles and gimbals are connected by swivel joints. However, these parts can be damaged by rocks, potholes, and other objects on the road.

Vibrations, a knocking sound, and abnormal handling are all signs of this type of damage.

If a gimbal is not adequately lubricated or becomes damaged by water, dirt, or salt, it must be replaced

Furthermore, axle seals can leak and cause the axle to wear out prematurely because it gets contaminated by water and dirt. When this happens you might hear strange noises from your axles.

In a front wheel drive vehicle, the sound would be at the front, in a rear wheel drive vehicle it would be at the back and in an all-wheel drive vehicle it can come from either side.

In an extreme case, a damaged axle could cause the wheels to lock or wreck the transmission.

The certified technicians at NAPA AUTOPRO have the expertise to diagnose axle problems and replace any necessary parts.

How often do you need to maintain your axle?

Axles wear out over time.

The certified technicians at NAPA AUTOPRO can perform a visual inspection to check if a joint or axle is damaged, or if a gimbal boot has been penetrated. Make sure to consult your NAPA AUTOPRO expert if you suspect any of these problems.

It is important to take care of axle maintenance work as soon as you become aware of the problem and before the damage gets worse and more expensive to repair.
