CV joints and axles, repaired properly the first time

A CV joint transfers power from the gearbox to a driven wheel while letting that wheel steer and move over bumps. CV joint and axle repair usually means one of two jobs: replacing a split CV boot before dirt wrecks the joint, or replacing a worn CV axle that clicks on turns. Wheel bearing repair is closely related, and done with the same wheels-off access.

The reason this is workshop work, not a quick fix, is that the symptoms overlap. A click on turns points to a worn outer CV joint, a growl that rises with speed points to a wheel bearing, and a vibration under load can be either, or a driveshaft problem entirely. Guessing wastes money. With the vehicle on a hoist and the wheels off, we can grip each joint, spin each bearing and read the wear directly.

Getting it wrong is expensive:

• Replace an axle when the boot was the only problem, and you have paid for parts you did not need
• Ignore a split boot, and a small reboot job becomes a full axle in a few weeks
• Chase a CV joint when the real fault is a wheel bearing, and the noise never goes away

We work on the CV boots, CV joints, driveshafts and wheel bearings on cars, utes, vans and light commercials, front-wheel drive, rear-wheel drive and four-wheel drive.

CV boots:

• Both boots on each axle checked for splits, cracks, weeping grease and missing clamps
• A boot caught early replaced with a new boot, fresh grease and clamps, saving the joint
• A damaged or insecure CV boot that leaves the joint exposed flagged as a Warrant of Fitness failure item

A CV boot is cheap. The joint it protects is not. Caught early, before grit has scored the bearing surfaces, most split boots are a reboot rather than a full axle replacement.

CV joints and axles:

• Outer joints tested for click and play on full lock, inner joints for clunk under acceleration
• A worn, contaminated or noisy joint replaced as a complete CV axle rather than gambling on a joint already damaged
• Quality new or reman CV axles matched to your exact vehicle, fitted with new circlips and hub nuts and torqued to manufacturer specification

On most modern vehicles, replacing the whole CV axle, the driveshaft with both joints, is more reliable and often no dearer than rebuilding a single joint, so that is usually the honest recommendation. We will always tell you which way the numbers fall for your car.

Wheel bearings:

• Each hub checked for roughness, growl and play with the wheel off
• Front or rear wheel bearing replacement, pressed or bolt-on hub-assembly type depending on your vehicle
• Bearings torqued to specification and road-tested to confirm the growl is gone

Wheel bearings and CV joints sit next to each other and often get blamed for one another. Because we have the wheels off anyway, we can tell the difference for certain and fix the one that is actually worn.

The classic CV joint symptom is a rhythmic clicking or knocking that gets louder when you turn, especially on a tight, slow corner like a roundabout or a car park entrance. Other signs are worth knowing:

• A clicking or knocking on turns, usually a worn outer CV joint
• A clunk when you accelerate or take up drive, often an inner CV joint
• Dark grease sprayed around the inside of a wheel or the wheel arch, a split CV boot throwing its grease
• A humming or growling that changes with speed or when you lean the car into a corner, usually a wheel bearing
• A vibration through the floor or steering that comes on under load

Can you still drive with a bad CV joint? For a short distance, usually yes, but it is not something to leave. A clicking joint is already worn, and driving on it lets the damage spread until the joint can seize or, in the worst case, fail completely and leave the car undriveable. A split CV boot or a joint with play is also a Warrant of Fitness failure, so it will need sorting before your next WOF regardless. The sensible move is to get it looked at while it is still clicking, not once it is grinding.

To book, call (07) 847 3339 or use the contact form, and tell us when the noise happens, on turns, under acceleration, or at open-road speed. That tells us where to look first. If the car is still safe to drive, a morning drop-off gives us time to diagnose and get parts in if needed.

On the day, the vehicle goes on the hoist and the wheels come off. We grip and twist each CV joint to feel for play, spin each wheel bearing by hand to feel for roughness, and check both boots for splits and lost grease. If we find work beyond what you booked for, we call you with the fix and an estimate first. Nothing gets done without your sign-off.

Once you approve, we reboot a sound joint or fit a quality new or reman axle or bearing, torque everything to manufacturer specification, and road-test the car to confirm the click, growl or vibration is gone. You leave with a written summary of what we did and anything else we noticed underneath, with no pressure to book it in on the spot.

We quote every CV joint, axle and wheel bearing job individually once we have seen the vehicle, and we confirm the cost with you before any work starts. We do not publish our own rates, because the right repair, and its price, depends entirely on which fault we find and what your vehicle takes.

Across New Zealand, replacing a single CV axle typically costs between $300 and $800, a split CV boot repaired before the joint is damaged typically costs between $150 and $400, and wheel bearing replacement typically costs between $250 and $650 per hub, though the exact price depends on your vehicle and the extent of the work. For an accurate quote for your vehicle, get in touch with our team.

What moves the price:

• Repair or replace: a reboot of a sound joint is cheaper than a full axle, which is why early diagnosis pays
• Vehicle type: a common front-wheel-drive hatch is simpler than a four-wheel-drive ute with longer, heavier shafts
• Part grade: quality new axles cost more than reman units, and we will explain the trade-off for your car
• One side or both: worn joints often come in pairs, and doing both at once can save on labour
• Wheel bearing type: a bolt-on hub assembly differs from a pressed bearing that needs the hub removed

Our workshop is on Kahikatea Drive in Frankton, a couple of minutes from the Hamilton ring road and easy to reach from Hillcrest, Rototuna, Te Rapa, Chartwell and Glenview. Clicking CV joints and worn wheel bearings are everyday work for us, and cars come in from right across the Waikato, commuters from Cambridge and Te Awamutu, family wagons from Huntly and Ngaruawahia, and utes and four-wheel drives from Morrinsville and out toward Raglan, where gravel is hard on boots and bearings.

The workshop is open Monday to Friday, 7:30 AM to 4:30 PM, closed weekends. If your car is still safe to drive, book a morning drop-off and we will diagnose the noise, quote the fix, and let you know whether the parts are on the shelf or coming in that day.
