Nissan Murano Z50 is a crossover that has gained popularity due to its reliability and comfort, but even such cars have weaknesses. One of them is drive shaft sealswhich wear out over time, leading to oil leaks and serious breakdowns. If you notice oil stains under the car or hear extraneous noises from the wheels, the problem may lie in the seals.

In this article we will look at how independently diagnose a malfunction of the drive seal on Murano Z50, what tools are needed for replacement, and why saving on the quality of spare parts can result in expensive repairs. And we’ll also reveal the secret of factory defects in oil seals on models 2008–2014, which even official dealers are silent about.

Signs of wear on the drive oil seal on a Nissan Murano Z50

The first sign of a problem is oil smudges on the inside of the wheel or near the CV joint. On Murano Z50 Drive seals most often “leak” after 100–120 thousand kilometers, but with aggressive driving or bad roads, wear may occur earlier. Please note:

  • 🔴 Oil stains under the car after parking (especially from the front left wheel - the load is higher there).
  • 🔊 Crunching or grinding noise when turning the steering wheel - this may mean that oil has got onto the CV joint.
  • 🛠️ Vibration at a speed of 60–80 km/h, which disappears when accelerating or braking.
  • 💧 Reduced oil level in the box (if the drive oil seal is connected to the gearbox).

On Murano Z50 with all-wheel drive AWD Rear drive oil seals fail less frequently, but diagnosing them is more difficult - a lift or inspection pit is required. If you ignore the problem, the oil will begin to corrode the CV joint boots, which will lead to their rupture and dirt getting into the mechanism.

⚠️ Attention: On models produced in 2010–2012, drive oil seals often become “tanned” due to poor-quality material. If during inspection you find cracks in the rubber, replace the part immediately, even if there are no leaks yet.
📊 How often do you check the condition of the oil seals on your Nissan?
  • Once every 10 thousand km
  • Only when symptoms appear
  • Never checked
  • I only trust service stations

Causes of premature wear of oil seals

Seals on Nissan Murano Z50 designed for 150–200 thousand km, but break down much earlier. Main reasons:

  1. Natural aging of rubber — over time, the material loses its elasticity, especially with temperature changes.
  2. Aggressive riding — sudden starts and braking increase the load on the drives.
  3. Bad roads — impacts on the suspension displace the shaft, causing the oil seal to deform.
  4. Poor quality oil — cheap transmission fluids corrode rubber.
  5. Factory defect - on Murano Z50 In the first years of production (2008–2010), the oil seals often had defective geometry.

Oil seals on machines with CVT JF011E — here oil starvation due to leaks can lead to box overheating and its failure. If you notice that the variator has begun to “kick” or there is a burning smell, check the oil level and the condition of the seals.

💡

When replacing the drive oil seal with Murano Z50 always check the condition of the CV joint. If there are traces of oil on it, replace the boot, otherwise dirt will quickly damage the mechanism.

Which oil seal to choose: original or analogue?

There are three types of oil seals on the market for Nissan Murano Z50:

Type Article Manufacturer Pros Cons
Original 39300-4M000 (front)
39300-4M001 (rear)		 Nissan Guaranteed compatibility, long service life High price (from 2500 rubles per piece)
Analogue premium SKF VKDA 35353 SKF (Sweden) The quality is not inferior to the original, the price is 30% lower There are fakes
Budget analogue CORTCO 23010040 Corteco (Germany) Low price (from 800 rub.) Service life is 1.5–2 times less than the original

For Murano Z50 with a mileage of more than 150 thousand km, we recommend original oil seals or SKF - they can withstand loads better. If your budget is limited, take it Corteco, but be prepared to replace it after 50–60 thousand km.

Important: check when purchasing marking on the seal. The original must have a logo Nissan and batch number. Counterfeits are often sold without packaging or with blurred engraving.

Step-by-step instructions for replacing the drive seal

Replacing the oil seal with Nissan Murano Z50 requires skill and tools. If you are not confident in your abilities, entrust the work to professionals. For self-repair you will need:

32 mm socket for unscrewing the hub nut

Socket wrenches 10, 12, 14 mm

Puller for CV joints (or pry bar)

Hammer and wooden spacer

Sealant Loctite 574 (to fix the new oil seal)

Torque wrench (to tighten the hub nut) -->

Work order:

  1. Remove the wheel and unscrew the hub nut (tightening torque - 220 Nm).
  2. Disconnect the CV joint from the hub using a puller or gentle hammer blows through the spacer.
  3. Remove the drive shaft out of the box. Be careful - oil may leak inside!
  4. Remove the old oil seal using a screwdriver or a special puller. Don't scratch the seat!
  5. Install a new oil seal, having previously lubricated its edge with transmission oil. Press the part evenly, without distortions.
  6. Reassemble everything in reverse order, making sure to tighten the hub nut to the correct torque.

After replacing, check the oil level in the box and add if necessary. If the oil seal has been severely worn, the variator or manual transmission may need to be flushed.

⚠️ Attention: On Murano Z50 with variator JF011E after replacing the drive seal, be sure to reset the gearbox adaptation via a diagnostic scanner (for example, Launch X431). Otherwise, jerking may occur during acceleration.
What to do if the oil seal gets stuck during installation?

If the new oil seal does not fit into place, do not hit it with a hammer! Lubricate the seat with soapy water or a special lubricant for rubber. Then use a mandrel (can be turned from an old oil seal) and press the part evenly with a press or vice.

Cost of replacing the drive oil seal in the service

Prices for replacing the drive oil seal Nissan Murano Z50 vary depending on the region and type of service station:

  • 🔧 Official dealer: 8,000–12,000 rub. for one oil seal (including diagnostics).
  • 🛠️ Independent service: 3,500–6,000 rub. (excluding spare parts).
  • 🏠 Self-replacement: 800–2,500 rub. (only the cost of the oil seal).

Saving on work can result in additional expenses. For example, if a technician presses the oil seal in incorrectly, it will begin to leak after 1–2 thousand km. Therefore, choose a service with good reviews and a guarantee on work.

The average bill for a comprehensive replacement of oil seals for both drives (front and rear) with original parts is: 15,000–20,000 rub. This amount includes:

  • Oil seals (2 pcs.) — 5,000–7,000 rub.
  • Work - 6,000–8,000 rubles.
  • Oil for topping up (if necessary) - 1,000–2,000 rubles.
  • Suspension diagnostics (optional) — RUB 1,500–2,500.

Common mistakes when replacing the drive seal

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. That's what can't do when replacing the oil seal with Murano Z50:

  • 🔨 Use sharp objects to remove the old oil seal - this scratches the seat and leads to leaks.
  • 🛢️ Do not lubricate the new oil seal before installation - dry rubber will wear out quickly.
  • 🔩 Tighten the hub nut - this deforms the bearing and leads to wheel play.
  • 🚗 Do not check the CV joint after replacement - if it is already worn out, the new oil seal will not last long.

Another common mistake is using sealant instead of proper pressing. Sealant can temporarily seal the leak, but it does not replace a tight seal. After 5–10 thousand km, oil will still begin to ooze.

💡

If after replacing the drive oil seal with Murano Z50 There was a hum from the wheel - most likely the wheel bearing was damaged. In this case, it needs to be replaced.

Prevention: how to extend the life of drive seals?

To ensure that the drive seals are on Nissan Murano Z50 last longer, follow these recommendations:

  • 🛣️ Avoid sudden starts and braking - this reduces the load on the drives.
  • 🔧 Check the oil level in the box every 15 thousand km (for a CVT - every 10 thousand km).
  • 🌡️ Don't overheat the transmission - Monitor the oil temperature, especially in traffic jams.
  • 🚿 Wash wheel arches in winter — salt and reagents corrode the rubber of the seals.
  • 🔄 Change the oil in the box every 60 thousand km (even if the manufacturer claims that it is “for the entire service life”).

Pay special attention CV joint boots. If they are torn, dirt will quickly enter the mechanism, and the drive oil seal will work under increased load. Check the boots at every service - it will take 5 minutes, but will save thousands on repairs.

For Murano Z50 with all-wheel drive AWD We recommend treating the oil seals with silicone grease once a year (in spring) - this will prevent the rubber from cracking due to temperature changes.

FAQ: Frequently asked questions about Nissan Murano Z50 drive seals

Is it possible to drive with the current drive seal?

Short term - yes, but not worth the risk. If oil gets on the CV joint, it will fail within 1–2 thousand km. And if there is a leak from the box, oil starvation and jamming of the variator may occur. The maximum that can be done is to drive to the service center, constantly monitoring the oil level.

How to distinguish a drive seal leak from a gearbox seal leak?

A drive seal leak is usually visible on the inside of the wheel or near the CV joint. A leak in the gearbox seal (for example, the input shaft seal) manifests itself as oil spots under the car closer to the center. Also, if the gearbox seal leaks, oil will drip even when the car is standing, and if the drive seal leaks, oil will drip only after driving.

How long does it take to replace a drive seal?

The service work takes 1.5–2.5 hours per oil seal (depending on complexity). When replacing it yourself, it takes beginners 3–5 hours, and experienced craftsmen — about 1 hour.

Is it necessary to change the oil in the box after replacing the oil seal?

If the oil seal leaks heavily and the oil level drops, be sure to add fluid to the normal level. There is no need to do a complete oil change, but if the oil is old (more than 50 thousand kilometers) or has a burning smell, it is better to replace it completely.

Can oil seals from other Nissan models be used?

No, drive seals Murano Z50 unique in size and shape. For example, oil seals from X-Trail T31 or Qashqai J10 will not fit - they have a different internal diameter. Always check the part number using the vehicle's VIN.
