The steering is a critical component of any vehicle, and Nissan Sunny is no exception. This is where the driver transmits his commands to the wheels, ensuring safe movement on the road. However, over time, any mechanism wears out, and one of the most vulnerable points in the control system is steering cross (steering shaft driveshaft).
This small element, located between the steering column and the steering gear, experiences enormous loads every time the steering wheel is turned. If you feel play or hear strange sounds, you cannot ignore the problem. Timely replacement steering shaft cardan will save you from costly steering rack repairs in the future and ensure the car's predictability on the track.
Symptoms of wear on the steering cross on a Nissan Sunny
The malfunction can be determined even before the steering wheel becomes completely uncontrollable. Most often, the driver notices the problem when driving on uneven roads or during sudden maneuvers. The appearance of a knock or squeak when turning the steering wheel is the first signal that spline connection requires attention.
Pay attention to the nature of the knock. If it is heard specifically in the area of the steering column, and not in the suspension, then the reason with a 90% probability lies in the crosspiece. When the bushings or splines themselves wear out, a gap appears, which creates a shock when the direction of rotation changes.
- 🔊 A distinct knock or click is heard when turning the steering wheel in place or at low speed.
- 🔄 There is a noticeable play in the steering wheel that cannot be eliminated by adjustment.
- ⚙️ The steering wheel rotates jerkily, especially in extreme positions, and there is a feeling of “biting.”
- 🚗 The car begins to “float” along the road, requiring constant direction adjustments.
Sometimes the problem is disguised as a malfunction of other components, so it is important to carry out thorough diagnostics. Failure to correctly assess symptoms may result in replacement of faulty parts such as steering rack or suspension silent blocks, instead of replacing a simple cross.
Why does the steering shaft driveshaft fail?
Main enemy steering cross - this is moisture and dirt that enters the mechanism through worn boots. In the conditions of Russian roads with reagents and frequent temperature changes, corrosion of the splines occurs very quickly. Even original spare parts from Nissan may fail prematurely if the protective elements are damaged.
An additional factor is vibration transmitted from the road. If the quality of the road surface is poor, the shock loads on the driveshaft increase many times over. The metal gets tired, microcracks appear, which over time lead to the complete destruction of the bushings or splines.
- 💧 Lack of lubrication inside the cross due to washing away dirt and water.
- 🛣️ Operating a vehicle on low-quality roads with high vibration.
- 🏗️ Natural wear and tear of materials after a long mileage (usually more than 100 thousand km).
It is important to understand that ignoring the problem leads to the fact that a jammed shaft can block the steering wheel at the most inopportune moment. This is a direct threat to the life of the driver and passengers.
⚠️ Attention! If, when turning the steering wheel, you feel that it may “freeze” in one position, immediately stop driving and call a tow truck. Locked steering while driving is deadly.
How to choose the right replacement part
There are many offers on the auto parts market, from cheap analogues to expensive originals. For Nissan Sunny the choice depends on your budget and plans for further operation of the car. The original will always be the best solution, as it undergoes strict quality control and has precise tolerances.
However, if the original steering cross is too expensive, you can consider high-quality analogues from trusted manufacturers. The main requirement for such a part is the presence of high-quality lubricant and reliable boots that will protect the mechanism from external influences.
- 🏆 Original (OEM) - guarantee of exact size match and durability.
- 🛠️ A high-quality analogue (for example, from TRW or Lemförder brands) - good value for money.
- ⚠️ Cheap Chinese analogues often have poor steel and quickly become loose.
When purchasing, be sure to check for anthers. Many cheap options are sold without them, which will lead to rapid failure of the new part. Also pay attention to the type of fastening: Nissan Sunny Different years of manufacture may differ in the size of the splines and the method of fixing the bolts.
- Original from dealer
- High-quality analogue (TRW/Lemförder)
- Budget analogue
- Used part from disassembly
Preparation for replacement and necessary tools
Before starting work, it is necessary to prepare the workplace and tools. Replacement steering shaft cardan is a procedure that can be performed in a garage, but requires accuracy and certain skills. You will need a hole or lift to access the underside of the car.
You need to collect the following set of tools: spanners and socket wrenches (usually 10, 12, 14), hammer, pry bar, Litol-24 lubricant or similar, as well as a new set of crosspieces. Don't forget the rust remover if the bolts are stuck.
☑️ Necessary tools and materials
Pay special attention to safety. Make sure the vehicle is securely supported on stands or a lift. Before starting work, disconnect the battery to avoid accidental short-circuiting of the wiring when dismantling interior elements.
⚠️ Attention! When working under a vehicle, never rely solely on a hydraulic jack. Always use safety stands (goats) under the body to avoid the risk of the machine falling.
Step-by-step instructions for replacing the crosspiece
The replacement process begins with dismantling the interior elements that block access to the upper part of the steering shaft. You will need to remove the lower steering column trim to get to the upper spider flange. Unscrew the mounting bolts, but do not remove them completely at once.
Next, move to the bottom of the car. From below, in the engine compartment or under the bottom, find the junction of the shaft and the steering rack. Unscrew the nuts or bolts securing the bottom flange. A difficulty often arises here: the shaft may be stuck to the rack. Use penetrating lubricant and carefully tap the shaft through the wood spacer with a hammer.
What to do if the shaft is stuck to the rack?
If the shaft does not give in, try heating the joint with a hair dryer. Do not use open flames as there are rubber seals and wiring nearby. You can also gently tap the end of the shaft through the spacer to knock off rust, but do not hit the shaft itself to avoid damaging the splines.
After removing the old part, clean the splines on the shaft and on the steering rack. Apply fresh grease to the splines of the new steering cross before installation. This will ensure smooth operation and extend the life of the unit. Install the new part, aligning the marks (if they were made before removal to maintain the angle).
Before unscrewing the bolts, be sure to mark the shaft and flange with chalk or a marker in order to maintain the original installation angle during assembly and avoid wheel alignment problems.
The bolts must be tightened to a specific torque. Don't overtighten them to avoid stripping the threads, but don't leave them loose either. After installation, check the ease of rotation of the steering wheel. If everything is done correctly, the knocking should disappear.
Proper lubrication of the splines and careful tightening of fasteners is the key to long service life of the new cross and the absence of extraneous sounds in the steering.
Checking operation and features after replacement
After completing the installation work, it is necessary to check the control system for any play. Turn the steering wheel left and right as far as it will go, listening for extraneous sounds. The steering wheel should rotate smoothly, without jerking or jamming. If the knocking noise persists, perhaps the reason is not only in the crosspiece, and you need to check other components.
Be sure to test drive on a safe section of the road. Pay attention to the car's behavior when driving in a straight line and when cornering. The steering wheel should return to the center position on its own after completing the maneuver.
- ✅ Check for vibration on the steering wheel when driving at different speeds.
- 🛑 Make sure that the steering wheel does not jam in extreme positions.
- 🔍 Inspect the mounting points for lubricant leaks or loose bolts.
If the replacement was done efficiently, the car will become more obedient and responsive. However, remember that when removing the steering shaft, the wheel alignment angles may have been disrupted.
Do I need to do a wheel alignment after replacement?
Yes, after removing the steering shaft or dismantling the steering rack elements, it is strongly recommended to visit a wheel alignment stand. This will ensure correct suspension geometry and even tire wear.

Frequently asked questions about the steering cross
At the end of the article, we have collected answers to the most popular questions that owners have. Nissan Sunny when diagnosing and repairing steering.
Is it possible to replace only one part of the cross?
Technically this is possible if the crosspiece is collapsible, but on most modern cars Nissan the cross is a non-separable unit. It is recommended to replace the entire set to ensure even wear.
How long does it take to replace?
An experienced master will complete the job in 1–1.5 hours. It may take 2-3 hours for a beginner, especially if the bolts are stuck and require a thorough treatment with WD-40 or heat.
Do I need to change the steering rack boot?
If you damage the boot when dismantling the shaft, it must be replaced. Even if it looks intact, when the shaft is removed, the protective rubber is often deformed, which will lead to dirt getting into the rack in the future.
Why did the knock persist after replacement?
The knocking noise can be caused by play in the steering rack itself, wear on the silent blocks of the levers, or a problem in the ball joints. Diagnostics must be comprehensive to exclude all possible sources of noise.
Is it possible to drive with a broken cross member?
Absolutely not. Driving with a broken crosspiece can lead to a complete loss of control of the car, since the shaft can become detached from the rack at any time. This is an emergency situation.
Always keep the phone number of a good towing service handy if you are planning a long trip with an older car. Safety comes first.
Remember that regular inspection of your steering is the key to your safety on the roads. Timely replacement of the steering cross on a Nissan Sunny prevents expensive repairs to the steering rack and maintains vehicle controllability.
