How to replace a CV axle
A clicking noise on tight turns is the classic sign of a worn CV joint. A new axle shaft costs more than a boot kit but takes less time and gives you a fresh joint on both ends.

This is a general guide, not a manual for your car. Your vehicle's service manual comes first, especially for torque values, fluid types and capacities. Support the car on the lift locks or jack stands before you go under it, wear eye protection, and if a step feels wrong, stop and ask us. We do not do welding, grinding or painting in the bays.
Look these up before you book
- Axle nut torque
- Left or right shaft and the right part number
- How the inner joint is held in the transmission
Tools
- Large axle nut socket
- Breaker bar and torque wrench
- Pry bar
- Drain pan
- Sockets
- Seal driver or a socket for the new seal if needed
Parts and fluids
- CV axle shaft for the correct side
- Transmission fluid to top up what escapes
- New axle nut
There is an AutoZone nearby, and during business hours parts usually reach the shop in about 10 to 20 minutes. Forgot a filter or need a different size? Order it, keep working, and do not lose your slot.
The retailer's own vehicle picker confirms what fits your car. Always compare the part number with your old part.
Step by step
- Loosen the axle nut on the groundBreak it loose before you lift if you can.
- Raise the car and remove the wheelSupport the car on the lift or stands before you reach into the wheel well.
- Disconnect the lower control arm or knuckle boltsEnough that you can swing the knuckle out.
- Pry the inner joint out of the transmissionPop it free with a pry bar. Expect a little fluid.
- Pull the outer joint through the hubTap it if it sticks.
- Fit the new axlePush the inner joint home until it clicks, then thread the outer end through the hub.
- Torque and refillTorque the nut, refit the wheel, then check transmission fluid.
Mistakes to avoid
- Over-bending the joint and damaging it
- Pulling on the axle so hard that it damages the transmission seal
- Reusing the old axle nut when it is a one-time use
Stop and ask for help if
- If a seal is leaking at the transmission, replace it at the same time. If you are unsure, ask.
Doing it in our bays
2-post lift. Book at least four hours in case it fights you.
Every bay has air, power, work lights and jack stands, and the lift bays come with a short safety walkthrough. Bring your own hand tools, parts and fluids. New to lifts? Read how your first visit goes.
Questions
Is the click always the CV joint?
Most often, yes, especially if it clicks on tight turns. A torn boot with grease on the inside of the wheel is another clue.
