The steering is a critical component of any vehicle, and Nissan Sunny This is no exception. Over time, especially when used on bad roads, the mechanism begins to show characteristic signs of wear that are simply dangerous to ignore. You may feel play in the steering wheel, hear a knock when passing speed bumps, or notice that the steering wheel has become harder to turn.

Ignoring these symptoms leads not only to discomfort while driving, but also to a complete loss of control in an emergency. Replacing the steering rack is a complex but necessary procedure that requires both theoretical knowledge and practical skills. In this article we will look at all the nuances: from diagnostics to final assembly, so that you can make an informed decision about repairs.

Diagnosis of steering mechanism faults

Before proceeding with dismantling, you need to make sure that the problem lies in the rail. Often owners Nissan Sunny They confuse a knock in the steering column or suspension with a malfunction of the mechanism itself. Correct diagnosis will save you time and money. Pay attention to the nature of the sound and feel of the steering wheel.

If you hear a metallic grinding sound or feel jamming when turning the steering wheel, this is a sure sign of wear on the gear pair or bushings. It is also worth checking the condition of the boots: a torn boot leads to dirt and moisture getting inside the mechanism, which causes accelerated corrosion and destruction of the seals. Symptoms of malfunction may be hidden in the initial stages.

Here are the main signs that require immediate intervention:

  • ๐Ÿš— The appearance of play in the steering wheel when driving in a straight line
  • ๐Ÿ’ง Liquid leaks PSF under the car near the front axle
  • ๐Ÿ”Š Knocking or squeaking noise when turning the steering wheel in place or while moving
  • โš™๏ธ The steering wheel does not return to the center position after turning

โš ๏ธ Attention! If you notice oil leaks under the car, do not delay repairs. Driving with a low level of fluid in the power steering can lead to jamming of the pump and complete failure of the entire system.

Sometimes the problem may not be with the rack itself, but with the tie rods or ends. Before purchasing a new part, be sure to check them for play. To do this, ask an assistant to rock the steering wheel while you look at the suspension components from below. If there is play in the tips, replacing them is cheaper and easier.

Choosing a new spare part: original or analogue?

Auto parts market for Nissan Sunny offers many options: from original parts to cheap analogues from Asia. Original from Nissan is guaranteed to last a long time and will fit perfectly, but its price may be too high for a budget car. Often the original slats are no longer supplied assembled, but only as repair kits.

Analogues from well-known brands such as Pelican, TRW or Delphi, can be an excellent alternative. They offer good value for money. However, if you choose a low-quality duplicate, you risk encountering the same wear and tear after only 10-15 thousand kilometers. Quality of materials plays a decisive role.

Consider the following options when purchasing:

  • ๐Ÿ”ฉ Original steering rack Nissan (It is better to check the catalog number by VIN)
  • ๐Ÿ›  Repair kits for restoring the old rack (if the body is intact)
  • โš™๏ธ High-quality analogues from proven European or Japanese manufacturers

It is also important to check the package contents. In some cases, the box does not include tie rods or mounting brackets, which will have to be purchased separately. Compare the items and accessories with your old part before paying.

Preparing tools and work area

To replace the steering rack with Nissan Sunny you will need a spacious box and a set of quality tools. The work requires access to the bottom of the car, so an inspection hole or lift is required. Do not attempt to carry out repairs outdoors in the cold season without special protective equipment.

You will need:

  • ๐Ÿ”ง Sets of sockets and ratchets (main sizes: 10, 12, 14, 17, 21)
  • ๐Ÿ”‘ Socket and open-end wrenches
  • ๐Ÿ’ง Container for draining old power steering fluid
  • ๐Ÿ— Jack and safety stands
  • ๐Ÿ’จ Steering wheel end remover

Before starting work, be sure to disconnect the negative terminal of the battery. This will prevent an accidental short circuit, especially if you have electric power steering (although many Nissan Sunny costs hydraulics). Also be prepared with rags and brake cleaner, as you will encounter dirt and oil as you work.

โš ๏ธ Attention! Use only working jacks and stands. Working under a vehicle without secure support is extremely life-threatening.

Clean the area around the steering rack before removing the bolts. Dirt that gets inside the mechanism during dismantling can lead to rapid wear even on a new part. Wash the connections with kerosene or cleaner to make the bolts easier to unscrew.

Step-by-step instructions for dismantling and installation

The replacement process begins with removing the wheel and engine protection. After this, you need to drain the fluid from the power steering system. To do this, disconnect the hoses from the rail and place the container. The liquid can be toxic, so wear gloves and follow safety precautions. Removing old hoses requires accuracy.

Next, you need to unscrew the steering ends from the steering knuckle arms. Use a puller to avoid damaging the threads. If the tip is stuck, you can gently tap the end of the lever with a hammer, but do not hit the threaded part directly. After disconnecting the tips, unscrew the bolts securing the rack itself to the body.

Follow this algorithm of actions:

  • ๐Ÿ”ง Disconnect the tie rods from the steering knuckles
  • ๐Ÿ”ฉ Unscrew the steering rack mounting bolts to the subframe
  • ๐Ÿ’ง Remove the old hoses and plug the holes to prevent dirt from getting into the new ones
  • ๐Ÿš— Carefully remove the rack through the wheel arch

Difficulties in dismantling old bolts

If the rack mounting bolts do not come off, use a penetrating lubricant (WD-40, Liqui Moly) and let it sit for 15-20 minutes. Sometimes heating the bolt with a hair dryer or blowtorch helps, but be careful with plastic parts and wiring nearby. In extreme cases, the bolt may need to be drilled out.

Installing a new rack is done in the reverse order. Apply thread locker to threaded connections to prevent vibration from loosening them. Tighten the bolts to the recommended torque using a torque wrench. Do not overtighten the fasteners as this may damage the rack housing.

The main task during installation is to ensure perfect alignment of the steering rods and the absence of distortions, otherwise the steering wheel will quickly wear out and knocking noises will appear.

After installing all components, connect the power steering hoses and fill in with new fluid. Make sure all connections are tight. Before starting the engine, bleed the system: turn the steering wheel from lock to lock several times with the engine off, then start the engine and repeat the procedure, monitoring the fluid level.

It is important to check the fluid level after the first start and top up if necessary. Air in the system can cause pump noise and poor amp performance. If the level drops after bleeding, check the joints for leaks.
