CV Axle Replacement: Clicks, Vibration, and Grease on Your Tire
If you hear a rhythmic clicking noise when turning — especially at low speed in a parking lot — the most likely cause is a worn CV (constant velocity) joint. Here is what it is, why it fails, and how we fix it.
What a CV axle does: On front-wheel-drive and all-wheel-drive vehicles, the CV axle transmits power from the transmission to the wheel while allowing the wheel to turn and move up and down over bumps. The CV joints at each end of the axle are flexible connections that allow this movement.
Why CV joints fail:
The CV joint is protected by a rubber boot filled with grease. When the boot tears — from age, road debris, or contact — the grease escapes and dirt and moisture enter the joint. Without lubrication and with contamination, the joint wears rapidly.
Houston's heat accelerates rubber degradation, making boot failures more common on higher-mileage vehicles.
Symptoms of a failing CV axle:
Clicking during turns — the classic sign. The clicking gets louder and more frequent as the joint wears. It is most noticeable during low-speed turns like parking maneuvers.
Vibration at highway speed — a worn inner CV joint (the one closer to the transmission) can cause vibration that feels similar to a tire balance issue.
Grease on the inside of the tire or wheel — if you see dark grease splattered on the inner fender or wheel, a boot has torn and grease is being flung out by the spinning axle.
Clunking when shifting from reverse to drive — excessive play in the CV joint can cause a noticeable clunk during direction changes.
How urgent is it? A clicking CV joint will not leave you stranded immediately, but it will get progressively worse. Eventually, the joint can fail completely, which means the wheel receives no power — or in extreme cases, the axle can separate. Do not ignore it for months.
Once a boot tears and the joint is clicking, cleaning and re-booting is rarely cost-effective. The standard repair is complete axle replacement — a remanufactured axle assembly is typically more economical than trying to replace just the joint.
Mobile CV axle replacement: This is a straightforward mobile repair on most vehicles. We remove the wheel, disconnect the lower ball joint or strut, pull the old axle, and install a new or remanufactured unit. Typical time is 1.5-2.5 hours per side.
If you hear clicking when turning, schedule service before the joint deteriorates further. Call or text us from anywhere in Katy, Sugar Land, Cypress, or Houston.
