The steering rack is one of the most critical components in the vehicle control system, ensuring the transmission of force from the steering wheel to the wheels. For owners Nissan Almera Classic this part often becomes a source of problems due to the design features and operating conditions on roads with poor surfaces. A characteristic knock, play or fluid leak become clear signals that the element requires immediate specialist intervention or self-repair.
Ignoring signs of malfunction can lead to loss of control at the most inopportune moment, which can have serious consequences. In this article we will look in detail at how to replace the steering rack yourself, what tools you will need, and what to look for when choosing components. We will also touch on diagnostic nuances so that you know for sure that the problem is in the rack and not in other suspension elements.
The main signs of a faulty steering mechanism
A breakdown can be determined not only by sounds, but also by changes in the car’s behavior on the road. The first and most common symptom is the appearance of a knocking sound when driving over bumps or turning the steering wheel. This sound often occurs due to wear on the bushings or gear pair inside the mechanism, which creates a gap between the parts.
The second important sign is a hydraulic fluid leak. If you see oil marks on the inside of the wheels or on the rack itself, this indicates damage to the seals or boots. In such cases, the fluid level in the power steering reservoir will constantly drop, requiring regular topping up.
- 🔊 The appearance of a hum or knock when turning the steering wheel in place or in motion.
- 💧 Visible leaks of power steering fluid under the car or on parts of the steering mechanism.
- 🎡 The occurrence of steering wheel play when the steering wheel turns without resistance.
- 🛑 Increased effort required to turn the steering wheel, especially at low speeds.
You shouldn’t attribute everything to wear and tear on the rubber elements, as the problem may be deeper. Sometimes a knocking noise can simulate a malfunction of steering rods or silent blocks, so accurate diagnosis is required before purchasing a new part.
⚠️ Attention: Do not delay repairs when the first signs of knocking appear. The destruction of the gear pair inside the rack can lead to it jamming while driving, which will make the car uncontrollable.
Choice of spare parts: original or analogue
The auto parts market offers a wide range of options for Nissan Almera Classic. The official original part number is often high in cost, which forces many car owners to look for worthy analogues. The quality of remanufactured slats can vary, so it is important to choose trusted suppliers and manufacturers.
There are several categories of spare parts: completely new units, reconditioned (repaired) racks and used disassembled options. Refurbished components can serve for a long time if they are properly repaired, but the risk of getting a “pig in a poke” is much higher than when buying a new product.
| Part type | Approximate price (RUB) | Pros | Cons |
|---|---|---|---|
| Original (Nissan) | 45 000 - 60 000 | Quality guarantee, exact match | High cost, long delivery |
| High-quality analogue | 25 000 - 35 000 | Good value for money | Variability in supply quality |
| Restored | 15 000 - 22 000 | Low price | Risk of hidden defects, short service life |
| From disassembly (used) | 8 000 - 12 000 | Lowest price | Unknown mileage and condition, no warranty |
When choosing an analogue, pay attention to brands specializing in steering mechanisms. Some manufacturers offer slats that are not inferior in performance to the original, but are much cheaper. It is critically important to check the package: the kit must include new boots, clamps and mounting bolts, as old ones often rust and are not suitable for re-installation.

- High-quality analogue
- Restored
- Used from disassembly
Preparing tools and work area
To successfully replace, you will need a set of standard tools, but some specific wrenches will make the task much easier. The work is carried out in an inspection pit or overpass, since access to the lower part of the car is limited. Make sure the surface is level and the vehicle is securely supported on the handbrake and stands.
You will need 12, 14, 17, 19 and 21 mm spanners and sockets. It is also worth preparing a puller for removing steering rods, since they are often impossible to dismantle by simply knocking them out without damaging the threads or ball pins. Also don't forget the rust remover and penetrating lubricant.
- 🔧 Set of sockets and ratchet with extensions.
- 🔨 Hammer and mounting spatula for detaching the levers.
- 🛠 Puller for steering ends and rods.
- 🧴 A can of penetrating liquid (WD-40 or equivalent).
- 🧴 Container for draining old power steering fluid.
Prepare new power steering fluid in advance, since when dismantling the rack, some of the oil will inevitably leak out. It is recommended to use the same brand as the one in the system to avoid mixing incompatible fluids, which could damage the pump.
Before starting work, be sure to photograph the location of the tubes and hoses so as not to confuse them when installing a new rail.
Step-by-step instructions for dismantling the old slats
We begin work by disconnecting the battery to avoid a short circuit due to accidental contact of wires. Next, you need to drain the fluid from the power steering system. Unscrew the hoses from the reservoir and redirect them into a container, then ask an assistant to turn the steering wheel all the way in both directions to completely remove the oil.
Next, remove the steering rods. Unscrew the nuts securing the ends and use a puller to press the fingers out of the swing arms. After this, unscrew the bolts securing the steering rack itself to the car body. There are usually four of them, but they can become very sour due to time and dirt.
☑️ Removing the steering rack
Carefully remove the rack through the wheel arch. Be careful not to damage the boots and hose clamps if they are still usable. During the removal process, it may be necessary to rotate the steering shaft to align the splines.
⚠️ Attention: The rack mounting bolts often stick to the body. Do not use excessive force to avoid stripping the threads, use heat and penetrating lubricant in advance.
Installing a new rail and connecting
Installation of the new part is carried out in the reverse order. Before installation, be sure to lubricate the spline joint of the steering shaft and lubricate all rubber seals. Insert the rail into the seat and tighten the mounting bolts, tightening them to the recommended torque.
Connect the tie rods and ends, making sure the pins are fully seated and secured with new nuts. Connect the power steering hoses, carefully checking the tightness of their fit and the condition of the O-rings. If the rings are old, it is better to replace them immediately.
Fill the reservoir with new fluid to the level and start the engine. Rotate the steering wheel from lock to lock several times to bleed the system and remove air. Monitor the fluid level and add it if necessary. Make sure there are no leaks at the hose connections.
