What are the 10 Signs Your Nissan Axle Assembly Needs Replacement?

1. Clicking Noise When Turning

A clicking noise from a Nissan axle while turning typically indicates the outer CV joint is the actual suspect. It resembles a fast, recurring click or pop, and it accelerates as you apply more gas while turning. It will be most audible at low speeds while the wheel is fully turned, such as when exiting a parking spot. Would you like to verify it by yourself?

Go to a vacant parking area, steer the wheel to its limit, and move slowly in a circular motion. Next, attempt it in reverse. A click when turning left typically indicates that the right axle is damaged, while a click when turning right usually suggests an issue with the left axle.

2. Vibration When Accelerating

Nissan axle vibration when accelerating is often a sign that the inner CV joint, the end that connects to the transmission, is wearing out. You'll typically feel the shaking build as you press the pedal, then settle down once you ease off.

There's one catch with Nissans. The Altima, Sentra, and Rogue use a CVT transmission, and a CVT can also shudder when you pull away gently. Before you replace anything, ask a mechanic to check the axle for looseness so you know which part is really at fault.

3. Clunking When Shifting Into Gear

Hearing a single thunk when you move the shifter into drive or reverse? Or when you switch from the gas to the brake? Something in the driveline has too much slack. On front-wheel-drive Nissans, that's often a tired CV joint. On trucks, worn gears in the differential or loose axle parts can make the same sound.

4. Grease on the Inside of the Wheel

Take a look behind your front wheels. If you see dark grease splattered across the inside of the rim, the brakes, or nearby suspension parts, a CV boot may have split. As the axle spins, it can throw grease out through the crack. Without enough grease, the joint wears out faster, so spotting the problem early may help prevent a bigger repair later.

5. Torn or Cracked CV Boot

Sometimes you can catch a bad boot before it leaks at all. Turn the steering wheel all the way to one side and shine a flashlight behind the front tire. Look over both boots, the one near the wheel and the one near the transmission, for splits, cracks or clamps that have slipped.

If the tear is fresh, a shop may be able to replace just the boot. But once dirt and moisture have worked their way inside, Nissan CV axle replacement makes more sense. A complete axle comes with fresh joints and boots at both ends, so you're not left with one worn joint still waiting to fail.

6. Steering Wheel Shakes at Highway Speed

A bent shaft or a badly worn inner joint can make the steering wheel shake once you're up to highway speed. The tricky part is that out-of-balance tires and failing wheel bearings can feel almost the same, so it's smart to rule those out first. Here's a useful clue: if the shaking changes when you speed up or lift off the gas, the axle is the more likely cause.

7. Humming or Growling From the Rear Axle

On a Frontier, Titan or another rear-drive Nissan, a hum or growl from the back that gets louder as you go faster usually means the differential gears or axle bearings are wearing out. A whine that rises and falls as you speed up and slow down tends to point to the gears. A growl that gets worse in turns is more often a bearing.

8. Gear Oil Leaking Near the Rear Wheels

Oily streaks on the inside of a rear tire, or spots on the ground under the back axle, are a sign that a seal is giving up. It could be the axle seal or the differential seal. Either way, low gear oil wears out the gears and bearings faster than normal. A leak at the axle seal can also coat the rear brakes, and that means they won't stop the truck as well as they should.

9. Wobbling While Driving

If the car feels wobbly, especially at lower speeds, the axle shaft may be bent. A badly worn joint can also make the car tug slightly to one side or feel loose when you accelerate. Hit a curb or a big pothole recently? That makes a bent shaft even more likely.

10. Car Won't Move When in Gear

This is the one nobody wants. The engine runs, the car seems to go into gear, but it just sits there. That usually means the axle shaft has snapped or its splines have stripped, and you may have heard a grind or a bang right when it happened. Don't try to drive it. Get it towed, and have a mechanic make sure it isn't the transmission.

On trucks, a snapped shaft can damage the differential or the housing as well. When that happens, swapping in one of our used axle assemblies is usually quicker than repairing each damaged part one by one.
