Steering rack Nissan Murano Z51 (third generation, 2015–2023) is a unit that often becomes a source of problems after 100–150 thousand kilometers. Owners complain of knocking noises, play in the steering wheel, power steering fluid leaks, or increased effort when turning. In 80% of cases, these symptoms are associated with wear of the internal components of the rack: oil seals, bushings, gear pairs or power steering. Ignoring malfunctions leads to deterioration in controllability and an increased risk of accidents, especially at high speeds.

In this article we will analyze all stages of steering rack repair Murano Z51 — from diagnostics to replacement of parts, including prices for work in services and the nuances of self-repair. We will pay special attention unique problem of this model: premature wear of the plastic bushings of the guide rack due to the design features of the electric power steering system (EPS). We also provide a table of spare parts compatibility and a list of tools that will be needed for the job.

Signs of a faulty steering rack Nissan Murano Z51

The first symptoms of problems with the rack are often attributed to the “features” of the suspension or tires. However there is 5 Key Signs, which directly indicate a malfunction of the steering mechanism:

• 🔊 Knocking or squeaking when turning the steering wheel (especially on a rough road) - indicates wear of the gear pair or bushings.
• 💧 Power steering fluid leak (red or brown oily fluid under the car) - a sign of damaged oil seals or seals.
• 🔄 Stiff steering wheel rotation in one of the directions (for example, only to the left) - indicates shaft deformation or bearing jamming.
• 🚗 Steering play more than 10° (checked on site with the engine off) - critical wear of the rack teeth or fasteners.
• ⚡ EPS error on the dashboard (C1609, C1610) - malfunctions of the electric booster, often associated with rack sensors.

On Murano Z51 with electric booster (EPS) knocking can occur even with working silent blocks and ball joints. This is due to the fact that The plastic guide rack bushings in this model have a factory defect - they dry out after 80–100 thousand km, which leads to play and vibration. In hydraulic racks (on diesel versions), leaks are more common due to wear of the power steering pump seals.

⚠️ Attention: If, when driving at speeds above 80 km/h, the steering wheel begins to “beat” or vibrate, check the rack immediately! On Murano Z51 this can be caused not only by wheel imbalance, but also by critical wear of the gear pair, which can lead to jamming of the mechanism.

Steering rack diagnostics: step-by-step instructions

Before repairing, it is necessary to accurately determine the cause of the malfunction. On Murano Z51 You can carry out the diagnosis yourself by following this algorithm:

1. Visual inspection:
   • 🔍 Check it out rack boots for cracks or oil stains (indicates a leak).
   • 🛠️ Take a look silent blocks And traction - they should not have any play.
2. Backlash check:
   • 🚗 Ask an assistant to sharply turn the steering wheel left and right, mientras you are looking at connecting the rack with the rods — play of more than 1–2 mm is unacceptable.
3. Leak test:
   • 💧 Turn off the engine, turn the steering wheel all the way and check the power steering fluid level (if any). A drop in level over a week is a sign of a leak.
4. Error scanner:
   • 📱 Connect a diagnostic scanner (for example, Launch CReader) and check the fault codes. Codes C1609–C1614 indicate problems with the rack sensors.

For accurate diagnosis hydraulic rack Removal and disassembly of the unit will be required. B electric rail (EPS) the main problems are identified through the scanner - often the torque sensor or control unit is to blame. On Murano Z51 with a mileage of more than 150 thousand km it is recommended to check gear pair condition - its wear is not always accompanied by obvious symptoms, but can lead to sudden steering failure.

• 🔨 Puller for steering rods (KUKKO 21-1 or equivalent).
• 🛠️ Vices and ties for springs.
• 🧴 Power steering fluid (Nissan PSF or Febi 06162).
• 🔍 Endoscope for examining internal cavities.

Work order:

1. Removing the rack:

   Disconnect the negative terminal of the battery, drain the power steering fluid, unscrew the rods and the fastenings of the rack to the body (4 bolts of 14 mm). Be careful with high pressure tubes — they cannot be bent!

2. Disassembly:

   Remove the anthers, retaining rings and remove the shaft. Check status gear pair - if there are chips or wear, replacement will be required.

3. Replacing oil seals and bushings:

   Install new seals (SKF VKJA 3515) and bushings (preferably cermet, article number 48501-4M00A). Lubricate the parts lithium grease (Molykote G-4500).

4. Assembly and pumping:

   Reassemble the rack in the reverse order, fill in new power steering fluid and bleed the system (turn the steering wheel all the way 5-6 times with the engine running).

For electric rack (EPS) Additionally you will need:

• 📶 Check the torque sensor circuit (the resistance between the contacts should be 4.5–5.5 kOhm).
• 🔧 Replace the electric motor brushes (if there is sparking or uneven operation).

Common mistakes when doing DIY repairs:

• ❌ Incorrect bolt tightening thrust (the moment should be 50–60 Nm).
• ❌ Using cheap seals (they tan after 10 thousand km).
• ❌ Unpumped power steering system (leads to airing and hum of the pump).

How to bleed the power steering system after repair?

1. Fill the liquid to the maximum. 2. Raise the front wheels on jacks. 3. Start the engine and slowly turn the steering wheel all the way left and right (5–6 times). 4. Add liquid and repeat the procedure until the bubbles disappear.

Selection of spare parts: original vs analogues

When repairing a steering rack Nissan Murano Z51 The owner is faced with the question: to buy original spare parts or analogues. The original guarantees compatibility, but is often 2-3 times more expensive. Below is a comparison of key details:

EPS sensor	Nissan 48520-4M000	Bosch 0 265 005 028	12 000 / 7 500

For Murano Z51 with a mileage of more than 150 thousand km it is recommended:

• 🔧 Toothed pair take only the original (Nissan 48500-4M000), since analogues wear out quickly.
• 🛠️ Bushings it is better to buy metal-ceramic (Febi or TRW) - they last 2 times longer than plastic ones.
• 💡 Power steering fluid - only Nissan PSF or Febi 06162 (cheap analogues foam and accelerate wear of the seals).

When purchasing analogues, pay attention to country of origin. For example, oil seals SKF (Sweden) or Corteco (Germany) more reliable than Chinese brands. For EPS slats The quality of the torque sensor is critical - non-original sensors often produce false errors C1609.

Prevention of steering rack malfunctions

Steering rack service life Nissan Murano Z51 can be extended if you follow simple rules:

• 🔄 Check the power steering fluid level regularly (every 10 thousand km) and top up if necessary. On EPS slats monitor the condition of the sensor contacts.
• 🚗 Avoid driving through deep potholes — impacts reduce the life of bushings and oil seals.
• 🔧 Change power steering fluid every 60 thousand km (even if there are no leaks). For Murano Z51 suitable only Nissan PSF or Febi 06162.
• 🛠️ Check the rack boots at every maintenance, cracks lead to dirt getting in and rapid wear.
• ❄️ Warm up the steering system in winter the first 1–2 minutes after starting, without turning the steering wheel sharply.

On models with EPS pay special attention to:

• 🔌 Wiring condition — oxidation of sensor contacts leads to errors C1610.
• 💧 Tightness of the rack housing — moisture ingress damages the electronic unit.

If you often drive off-road, install crankcase protection, which will protect the rail from impacts. It is also useful to treat rubber boots silicone grease - this will prevent them from cracking.

When repair is impossible: signs for replacing the rack

In some cases, steering rack repair Nissan Murano Z51 is impractical, and a complete replacement of the unit is required. This is relevant for the following malfunctions:

• 🔧 Strong production of gear pair (more than 0.5 mm) - leads to backlash and inaccurate control.
• ⚡ Short circuit in EPS unit (the rack does not respond to steering wheel turns).
• 💥 Cracks in the rack body - cannot be repaired, needs to be replaced.
• 🔄 Multiple failed repairs (if the knocking returns after 2-3 oil seal replacements).

On Murano Z51 with EPS common problem - electronics failure after moisture gets into the control unit. In this case, repairs cost more than replacement (about 30 000–40 000 ₽), so it makes more sense to buy contract rail (price - 25 000–35 000 ₽) or new (80 000–120 000 ₽).

When choosing contract slats pay attention to:

• 📝 Donor mileage (optimally up to 100 thousand km).
• 🔍 Condition of seals and anthers (they must be whole).
• 🔧 No backlash when checking on a stand.

⚠️ Attention: On Murano Z51 2018-2023 racks are equipped with updated EPS sensors that are not compatible with older control units. When replacing, check rack article number (For example, 48500-4M010 for restyling 2020).

FAQ: Frequently asked questions about steering rack repair Nissan Murano Z51

Is it possible to drive with a knocking rack?

Short term - yes, but it is dangerous. A knocking sound indicates wear on the gears or bushings, which can cause the steering wheel to jam at speed. On Murano Z51 with EPS knocking is often accompanied by an error C1609, which indicates a sensor malfunction. We recommend repair within 1-2 weeks of symptoms appearing.

How long does a repaired rack last?

With high-quality repairs (replacing oil seals, bushings, polishing the shaft), the rack will last 80,000–100,000 km. If you limit yourself to only replacing the power steering fluid or oil seals, the service life is reduced to 30,000–50,000 km. On Murano Z51 with EPS The service life depends on the condition of the torque sensor - it is recommended to change it every second repair.

Is it possible to repair a rack with error C1610?

Error C1610 indicates a malfunction rotation angle sensor or EPS control unit. In 70% of cases, replacing the sensor helps (part no. 48520-4M000). If the error remains, the problem is in the control unit, and the entire rack will have to be replaced. Before repairing, check the sensor circuit with a multimeter (the resistance should be 4.5–5.5 kOhm).
