Car suspension Nissan Cube first generation (body AZ10) is known for its reliability, but over time, even the toughest components require attention. One of the critical parts of the front suspension is ball joint, which connects the lever to the steering knuckle and ensures freedom of rotation of the wheel while maintaining its fixed position.
Ignoring problems in this area can lead to serious consequences, including the wheel being torn off the car while driving. Owners Nissan Cube It's important to understand how to recognize early signs of wear and how to properly replace a part to maintain drivability and safety. In this article we will look at all aspects, from diagnosis to final bolt tightening.
The role of the ball joint in the suspension of the Nissan Cube AZ10
The ball joint acts as a hinge, allowing the wheel to rotate in a horizontal plane and move up and down with the suspension. In design Nissan Cube it is attached to the lower control arm and pressed into the steering knuckle. This part experiences enormous loads, especially on our roads, where potholes and bumps are found everywhere.
During normal operation, the ball joint should provide smooth movement without play. However, over time, the boot that protects the hinge from dirt and moisture may tear. The penetration of abrasive particles into the mechanism leads to rapid wear of the ball pin and seat. If you feel that the steering wheel has become “wobbly”, this may be the first signal of problems with the suspension.
It is important to understand that replacing only one support may not be economically feasible if the vehicle's mileage exceeds 150 thousand kilometers. Often, the silent blocks of the lever and the anti-roll bar wear out along with it. Therefore, when play is detected, it is recommended to carry out a comprehensive diagnosis of the front axle.
Main wear symptoms and diagnostic methods
Identify the faulty ball joint on Nissan Cube This can be done both visually and by characteristic sounds. The surest sign is a metallic knock heard when driving over bumps, especially at low speeds. This sound occurs because the ball pin begins to “dangle” in the seat, hitting the walls when the load changes.
You can carry out diagnostics yourself using a jack and a pry bar. Raise the front wheel, place a secure support under the car and rock the wheel with your hands in a vertical plane. If at the same time you feel play in the hub area and hear a knocking sound, the problem is almost certainly in the ball or wheel bearing. To clarify the diagnosis, insert a prybar between the lever and the ball joint and try to unclench them.
- 🔍 Metallic knock when passing speed bumps.
- 🔍 The car pulls to the side when braking.
- 🔍 Uneven tire tread wear.
- 🔍 Steering wheel play that cannot be eliminated by adjustment.
Visual inspection can also provide clues. If boot The ball joint is torn, and grease or rust is visible inside, the part must be replaced immediately. You should not delay repairs, as jamming of the ball pin can cause the wheel to stop turning, which is extremely dangerous when maneuvering.
⚠️ Warning: Do not attempt to continue operating a vehicle with a faulty ball joint. Even a small play can lead to critical destruction of the unit at any moment, especially during sudden braking or turning.

Selecting suitable replacement parts
When selecting a new part for Nissan Cube AZ10 There are two main options to consider: original spare parts and high-quality analogues. Original part from Nissan (catalog number often starts with 54500-) is guaranteed to fit all sizes and materials, but its cost can be quite high.
There are many manufacturers on the market offering worthy replacements. Among the popular brands it is worth noting CTR, Moog, TRW and Lemforder. These companies produce ball joints with improved boot performance and higher quality ball pin alloys. However, it is important to avoid cheap fakes, which often do not last even half of the declared resource.
Be sure to check the contents of the new part. In some cases the ball joint is sold separately, and in others it is sold as an assembly with the arm. For Nissan Cube Most often it is the hinge itself that is changed, which is pressed into the lever. If the lever is deformed or has cracks, saving on replacing only the ball does not make sense.
| Brand | Type | Approximate price | Resource (km) |
|---|---|---|---|
| Nissan (Original) | Hinge assembly | High | 100 000+ |
| CTR | Analog (Korea) | Average | 80 000 - 100 000 |
| Moog | Analog (USA) | Average | 70 000 - 90 000 |
| Low segment | Analog (China) | Low | 20 000 - 40 000 |
Tools and preparation for replacement
To replace the ball joint yourself, you will need a standard set of tools, but there are several specific items without which the work may take longer or become impossible. First of all, this is a ball joint remover or a special fork. You will also need a powerful wrench and a set of sockets, including 19 mm and 21 mm for attaching the lever.
Don't forget to prepare a penetrating lubricant like WD-40 or similar. Suspension nuts Nissan Cube often stick due to dirt and corrosion, so the treatment should be carried out in advance, 15-20 minutes before starting work. You will also need a hammer, a pry bar and, preferably, a torque wrench for proper tightening.
☑️ Preparation for replacement
Work must be carried out on a flat surface. If you're doing this in a garage, make sure the floor is clean and there's no risk of slipping in the oil. Lift the front of the car, remove the wheel and place it securely under the sill or use a stand. Working under a machine that is only supported by a jack is strictly prohibited.
⚠️ Warning: Never rely solely on a hydraulic jack when working under a vehicle. Always use safety stands (shorts) or place the wheel securely under the sill.
Step-by-step instructions for replacing the ball joint
The replacement process begins with removing the wheel rim and fender liner protection if it interferes with access to the lower part of the lever. Unscrew the nut securing the ball stud to the steering knuckle. It is usually located under the cap and requires first unscrewing the lock washer or cotter pin (depending on the modification).
Use a puller to press the pin out of the steering knuckle. If there is no puller, you can carefully tap the joint with a hammer through the spacer, but do this extremely carefully so as not to damage the thread or the pin itself. After removing the pin, unscrew the bolts securing the lever to the body and subframe.
Remove the lever and turn it over. Using a special puller or a powerful press, press the old ball joint out of its seat. Clean the seat from rust and dirt. Install the new support, being careful not to damage the new boot when pressing. Make sure that the support is seated tightly and without distortion.
- 🛠️ Unscrew the ball pin nut.
- 🛠️ Press your finger out of the steering knuckle.
- 🛠️ Remove the suspension arm.
- 🛠️ Replace the ball joint on the lever.
Reassemble the assembly in reverse order. It is important not to confuse the position of the lever during installation. After all bolts are tightened, check that the ball pin rotates freely. It should not have any backlash, but it should not jam either. If the support comes complete with a new boot, be sure to lubricate the hinge with a special ball lubrication before installation.
What to do if your finger doesn't come out?
If the pin is stuck in the steering knuckle, try using a screw-driven puller. Sometimes it helps to heat the fist seat with a blowtorch (without fanaticism, so as not to damage the rubber), which will expand the metal and make removal easier.
Correct pressing of the new support is the key to long service life of the suspension. Avoid hitting the hinge itself with a hammer; use only mandrels of the appropriate diameter.
Nuances of tightening and wheel alignment adjustment
After installing the new part, the fasteners must be properly tightened. The ball stud nut is tightened to a certain torque, which is usually approx. 80-100 Nm. Exact values can be found in the service book Nissan Cube. Over-tightening can lead to rapid wear of the joint, and under-tightening can lead to its destruction.
The bolts securing the lever to the subframe also require monitoring the tightening torque. Often, after replacing suspension elements, the geometry of the wheels changes. Therefore, it is strongly recommended to perform the wheel alignment procedure on a special stand. This will ensure even tire wear and proper vehicle behavior on the road.
If you only replaced one ball joint, the wheel alignment still needs to be checked, since removing the lever will inevitably throw off the factory settings. Ignoring this stage will result in the car “pulling” to the side, and the tires will wear out unevenly after just a few thousand kilometers.
Common mistakes when repairing suspension
One of the most common mistakes is trying to “refresh” an old ball joint by applying lubricant through a syringe. This works extremely rarely and only for a short time, since the worn metal has already worn out. It is better to replace the part immediately than to waste time on temporary measures.
Another mistake is using the wrong pressing tools. Hitting the ball pin threads or using a sledgehammer to knock out the bearing can deform the lever or knuckle. Use only a specialized puller or hydraulic press for such operations.
It is also important not to forget about replacing the boot. If you change a ball joint, but the old boot remains in place and has cracks, then the new part will also quickly fail. The boot must be intact and fit snugly to the hinge body.
⚠️ Attention: Do not use a gas wrench to unscrew the ball pin nut if this is not provided by the design. This can damage the edge of the nut and make it impossible to loosen or tighten it later.
FAQ: Frequently asked questions
How long does the ball joint last on the Nissan Cube AZ10?
Under normal operating conditions and using high-quality spare parts, the life of the ball joint is from 80,000 to 120,000 kilometers. However, on bad roads this period can be halved.
Is it possible to change the ball joint without removing the arm?
Theoretically, it is possible if there is access to the bottom of the lever and a special puller, but this is extremely inconvenient and risky. It is recommended to remove the lever completely for quality replacement and inspection of other suspension components.
Do I need to replace both ball joints at once?
If the car has a lot of mileage and there is wear on one support, there is a high probability that the second one is in a similar condition. To save time and money (since the job of replacing both is the same), it is better to replace them as a set.
What happens if you don’t do a wheel alignment after replacement?
The car may move to the side when driving in a straight line, the steering wheel may be crooked, and the tires will begin to wear unevenly and quickly, which will lead to the need for their premature replacement.
How often should the condition of the ball joints be checked?
It is recommended to carry out a visual inspection and check for play every 15,000 - 20,000 kilometers, as well as at each scheduled maintenance. If knocking sounds occur, check should be carried out immediately.
