Signs The CV Axles On Your Vehicle Need To Be Replaced

On modern front-wheel drive cars, the CV axles (also known as half-shafts) deliver engine power to the wheels. In essence, the engine spins the CV axles and the axles are connected to the wheels, so they turn in response and your vehicle moves forward. It has a complex joint that enables smooth power delivery even as the front wheels rotate to steer or articulate over bumps and dips in the road. Over time, wear can cause damage to this joint, which can cause the CV axle to fail. Below, we'll tell you some of the warning signs to look out for that say the axles on your car might need to be replaced sooner rather than later.

3. Vehicle Will Not Move

Since the CV axles deliver engine power to the front wheels, If one of your CV axles has utterly and completely failed, the vehicle might not move at all. This kind of damage would most likely be caused by an accident. A snapped CV axle or disconnected universal joint is probably enough to prevent your car from being safely driven.

If that's the case, you'll want to get a tow to our service department. We'll simply replace the failed CV axle with a brand-new unit to get you back on the road.

You can make it easier to look at the inside of your vehicle's tires by turning the wheel as it's parked 

2. Grease On Inside Edge Of Front Tires

Before the CV axle fails entirely, you'll usually notice signs that the boot surrounding the universal joint has failed. The CV axle's universal joint is a grease-filled joint covered with a protective rubber boot. Road debris or stress over time can cause a rip in the boot, allowing the crucial lubricating grease to leak out. When it does, it'll tend to collect on the inside edge of your vehicle's front tires. If you suspect a problem with one of your vehicle's CV axles, grab a flashlight and take a peek under the vehicle and see if you notice any grease building up on the inside of your tires.

A clicking sound that develops when turning sharply could be due to a bad CV axle 

1. Rhythmic Clicking Noise When Turning

Once that lubricating grease has entirely leaked out of the protective boot, the joint will be dry. The metal components then won't smoothly slide against one another, but will rattle and clatter together, creating a clicking noise that gets faster and louder as you accelerate, or gets worse as your steering wheel turns. This is a sure sign that your CV axle needs to be replaced. A dry joint will wear out rapidly, and could quickly fail completely, leaving you stranded.
