Knock in the steering rack Nissan Almera Classic - one of the most common problems that owners of this car face after 100-150 thousand km. Many people immediately think about an expensive replacement of the unit, but in 80% of cases it is enough correct tighteningto restore clarity of control and eliminate backlash. However, there are nuances here: an overtightened rack will accelerate the wear of the mechanism, and a weak tightening will have no effect.
In this article we will look at how to determine that the rack needs adjustment, what tools are needed, and step by step We will show you the tightening process - from removing the protection to checking the result. You will also learn what mistakes beginners most often make and how to avoid them. If you've never worked with steering, don't rush to pick up the tools: read to the end first to see if you're up to the task.
Signs that the Nissan Almera Classic steering rack needs tightening
First signal - knocking sound when going over bumps, which feeds into the steering wheel or gas pedal. On Almera Classic (especially with a mileage of 150 thousand km) this is often due to wear of the bushings or loosening of the adjusting screw. But knocking can be disguised as other malfunctions, so it is important to differentiate the symptoms:
- 🔧 Steering play more than 10° (checked on the spot: sharply pull the steering wheel left and right - if the wheels do not react immediately, there is a problem).
- 🚗 Car withdrawal to the side when moving in a straight line (may also indicate wheel alignment, but coupled with a knock - a sign of a rack).
- 🔄 Stiff steering wheel rotation in one of the extreme positions (they talk about wear of the gear pair).
- 💧 Oil leaks on the rack boots (requires urgent repair, tightening will not help here).
On Nissan Almera Classic with hydraulic booster (power steering) the knocking noise may increase during cold starts as the oil in the system thickens. If the sound disappears after warming up, wear of the seals or lack of fluid is to blame. Tightening the rack will not eliminate the leak, but it can temporarily reduce the knocking noise by compensating for play.
⚠️ Attention: If the knock is accompanied creaking when turning the steering wheel, the problem may be in the ball joints or tie rods. Before tightening the rack, check these components!
Tools and materials for work
To tighten the steering rack Almera Classic You don’t need a professional tool, but there are some issues with access to the adjusting screw. Here's the full list:
| Tool/material | Purpose | Notes |
|---|---|---|
| 10mm wrench (socket or open-end) | Unscrewing the steering column protection | It is better to use an extension cord with a ratchet |
| Special key for tightening the rack (or 5 mm hexagon) | Backlash adjustment | On some versions Almera Classic need a key with a bend |
| Torque wrench | Torque control | Optional, but recommended for accuracy |
| WD-40 or similar lubricant | Processing of threaded connections | Apply 10–15 minutes before work |
| Flashlight or head light | Work area lighting | The adjusting screw is inconveniently located |
If you don't have a special tightening wrench, you can use 5 mm hexagon, but be careful: on some slats the screw has a non-standard profile, and it is easy to “lick” the edges with a regular wrench. Car repair shops often use homemade devices from an old socket wrench bent at the desired angle.
- Keys and sockets
- Torque wrench
- Hexagons
- None of the above
Step-by-step instructions: how to tighten the steering rack on a Nissan Almera Classic
Before starting work necessarily Place the car on a flat surface and secure the rear wheels with chocks. The slats are tightened only on a cold engine - when heated, the metal expands and the adjustment will be inaccurate.
Remove the terminal from the battery|Disconnect the power steering (if equipped) and drain the fluid|Clear the area under the steering wheel from dirt|Jack up the front part and remove the wheel (optional, for convenience)-->
Step 1: Accessing the Adjustment Screw
On Nissan Almera Classic The tightening screw is located under the steering column, behind the protective cover. To get to it:
- Remove the plastic trim under the steering wheel (snap off the clips or unscrew the screws with a 10 mm wrench).
- Move the mat and find the metal plate - you need to unscrew it.
- Under the plate you will see a rubber boot - carefully cut it off with a knife (then replace it with a new one).
The tightening screw is located at the end of the rack, closer to the interior. It is closed with a lock nut, which must first be loosened (but not completely unscrewed!).
Step 2: Adjusting the Backlash
This is the most critical stage. Turn the screw clockwise reduces backlash, against - increases. Recommendations:
- 🔩 Start by turning to 10–15° (no more than a quarter turn!).
- 🔄 After each turn, check the play with the steering wheel (the assistant should jerk the steering wheel sharply left and right).
- ⚠️ If the steering wheel becomes tight or appears creaking — you overtightened the rail! It needs to be loosened by 5–10°.
Optimal result: no play, but the steering wheel rotates smoothly, no snacking. On Almera Classic with power steering after tightening, it may be necessary to bleed the system (bleed air by turning the steering wheel all the way in both directions with the engine running).
If the knocking noise remains after tightening, check the condition of the rack boots. A torn boot allows dirt to pass through, which quickly wears out the gear pair. In this case, the tightening will give a temporary effect (1–2 months), after which the rail will have to be repaired or replaced.
Step 3: Fixation and assembly
When you have achieved the desired result:
- Tighten the locknut to torque 20–25 Nm (without a torque wrench, tighten “finger-tight” with moderate force).
- Install a new boot (the old one is already leaking).
- Assemble the plastic protection and check the operation of the steering wheel while driving.
⚠️ Attention: After the tightening, be sure to do wheel alignment! Even a small change in the rack geometry affects the wheel alignment angles.
Common mistakes and how to avoid them
Inexperienced car owners often damage the rack due to improper tightening. Here are the most common mistakes:
- 🔧 Screw tightening - leads to accelerated wear of the gear pair and a tight steering wheel. Signal: the steering wheel “bites” when turning in place.
- 🔩 Ignoring the Locknut — if it is not fixed, the screw will spontaneously loosen after 1–2 thousand km.
- 🚗 Hot pull-up — after cooling, the rack may “jam.” Always work on a cold car!
- 💧 Saving on anthers - an old torn boot will negate all efforts: dirt will quickly return the play.
Another mistake is tightening the slats when worn tie rods or ball joints. In this case, the backlash will remain, and you will waste your time. Always check these components before making adjustments!
What to do if after tightening the knocking intensifies?
If the knocking noise becomes louder, you may have overtightened the rack or damaged the gear pair. Immediately loosen the screw 10-15° and check the steering wheel. If the knocking noise does not go away, diagnostics will be required on the lift - the bushings or oil seals may be worn out.
When a lift doesn't help: signs of critical wear
Tightening the rack is temporary measure, which is effective only with small play (up to 0.5 mm). If the wear of parts is critical, adjustment will only worsen the problem. Signs that the rack needs to be repaired or replaced:
- 🔧 Metal scraping when turning the steering wheel (they talk about the destruction of the teeth).
- 💧 Oil flows through the seals (even after replacing the anthers).
- 🚗 The steering wheel turns jerkily (wear of the gear pair).
- 🔄 The lift does not remove the play (the screw is tightened all the way, but the knock remains).
On Nissan Almera Classic With a mileage of more than 200 thousand km, tightening the rack often gives an effect for 3-6 months. If after adjustment the knocking noise returns after a short time, get ready for repairs (replacing bushings, oil seals) or purchasing a contract rail.
Tightening a rack costs 500–1000 rubles (if you do it yourself), while a new rack costs 15–25 thousand rubles. But the savings are justified only with minor wear!
Cost of work in the service vs self-repair
In car services, the steering rack is tightened Almera Classic costs from 1500 to 3000 rubles (depending on the region). This price usually includes:
- 🔧 Steering diagnostics.
- 🔩 Backlash adjustment with checking.
- 🚗 System pumping power steering (if any).
- 📝 Work guarantee (usually 1-2 months).
Self-repair will cost less (the price for boots and lubricant only is up to 500 rubles), but there are risks:
- ❌ Drag the rail and ruin it.
- ❌ Do not notice related faults (for example, leaks power steering).
- ❌ Disturb alignment due to improper assembly.
If you are not confident in your abilities, it is better to contact the service. This is especially true for owners Almera Classic with power steering - this requires bleeding the system, and without experience it is easy to air the circuit.
FAQ: Frequently asked questions about tightening the steering rack
Is it possible to tighten the rack without a pit or lift?
Yes, but it's inconvenient. On Almera Classic the adjusting screw is located so that it can be reached from the passenger compartment by removing the protection under the steering wheel. However, without a pit it is difficult to control the condition of the anthers and rods. If you do not have experience, it is better to use an inspection ditch.
How many turns can you make when pulling?
Maximum - half a turn (180°) from the starting position. Usually 10–30° (a quarter turn) is sufficient. If after this the play remains, the problem is not in the adjustment, but in wear of the parts.
Do I need to drain the power steering fluid before tightening it?
No, unless you plan to remove the rack. The tightening is performed without disassembling the hydraulic system. However, after adjustment, bleeding may be required (bleed air by turning the steering wheel all the way while the engine is running).
How often do you need to tighten the rack?
During normal use - never. A tightening is only needed when play or knocking occurs. If the rack requires adjustment more than once every 50 thousand km, it needs to be repaired or replaced.
Can tightening the rack affect the wheel alignment?
Yes, but only slightly. If you did not change the linkages or remove the rack, the wheel alignment angles will remain within normal limits. However, after tightening it is recommended to check the alignment (costs 500–800 rubles).
