Axles carry power from the transmission or differential to the wheels. Front-drive and all-wheel-drive cars use CV axles with flexible joints; many trucks use solid axle shafts. Route 66 Auto Repair in Upland inspects both, looks for torn boots and worn joints, replaces damaged axles after written approval, and road-tests the car. A clicking sound when turning is the classic warning. Solid rear axles connect to the differential, which we check at the same time.
What are the signs of a failing axle?
- Clicking when turning sharply, as in a parking lot
- Grease sprayed inside the wheel
- Vibration during acceleration
- A clunk when shifting into drive
- Gear oil leaking at the wheel on a solid axle
Why does a torn CV boot matter so much?
The rubber boot keeps grease in and dirt out of the CV joint. Once it tears, grease flings out and grit gets in, and the joint wears quickly. A torn boot caught early may be replaceable on its own. Once the joint is clicking, replacing the complete axle is usually the practical fix.
Inland Empire heat dries boots, so we check them whenever the car is on the lift for other work, including brake service.
Our axle repair process
Step 1: Road test
We listen for clicking in turns and feel for vibration.
Step 2: Inspect
Boots, joints, seals and bearings are checked on the lift.
Step 3: Quote
The written estimate compares boot and axle options where both apply.
Step 4: Replace and test
The axle is installed, the axle nut is torqued to spec, and we road-test.

How pricing and timing work
CV axles are often available as complete units, which keeps labor predictable. Solid axle shafts and bearings can take longer. AAA members get 10% off parts and labor, up to $75. CV axle jobs are often same-day when the board allows. Related work is covered in our drivetrain services.
Aftercare
The clicking should be gone. Watch for grease on the inside of the wheel, which would signal a boot problem. Axles are usually not related to wheel alignment.
Frequently asked questions
How long can I drive with a clicking CV joint?
It varies, but the joint will keep wearing and can eventually separate, leaving the car unable to move. Get it replaced soon.
Can I replace just the CV boot?
If the joint is still quiet and clean, sometimes yes. Once it clicks, the axle usually needs replacement.
Do trucks have CV axles?
Four-wheel-drive trucks often use CV axles up front. Rear axles on most trucks are solid shafts inside a housing.
