Crossover owners Nissan Murano third generation (Z52 body) are often faced with the need to maintain the transmission system. The transfer case (transfer case) is a critical component that distributes torque between the axles. Ignoring the regulations for replacing lubricating fluid can lead to overheating of the differential and costly repairs to the all-wheel drive.
The procedure for changing the oil in the transfer case on the model Murano Z52 has its own characteristics that differ from its predecessors. The design of the components has been changed, and the requirements for viscosity and oil tolerance have become stricter. Choosing the right consumables and adherence to casting technology guarantee the durability of the transmission. In this article we will analyze all the stages of work, the necessary tools and common mistakes.
Many car owners try to save money and service the transfer case themselves, which is acceptable if you have the appropriate experience. However, if you are not confident in your abilities, it is better to entrust the work to professionals. It is important to understand that lack of tightness or incorrect oil level can lead to failure of the electronic clutch control unit.
Why change the oil in the transfer case and when to do it
Transfer case on Nissan Murano Z52 works under constant load conditions, especially when driving off-road or in slushy conditions. Inside the assembly there are gears and bearings that experience high mechanical stress. Over time, the oil loses its properties: it oxidizes, becomes contaminated with metal shavings and loses viscosity.
Timely replacement allows you to remove wear products and restore the protective properties of the lubricant. If you ignore the regulations, there is a risk of jamming the front axle coupling. This is fraught not only with failure of the all-wheel drive, but also with damage to the driveshaft.
The manufacturer's official regulations recommend replacement every 60,000 kilometers. However, if you operate the car in difficult conditions (dirt, frequent slipping, towing a trailer), the interval should be reduced to 40,000 kilometers. Level and condition monitoring Oil inspection can be done at every engine oil change.
Choosing the right oil and the necessary tools
For transfer case Nissan Murano Z52 the manufacturer requires the use of a specific liquid. Standard gear oils are often not suitable due to the way the electronic clutch operates. It is necessary to use original oil Nissan ATF Matic S or its certified equivalents meeting JWS 3309 specification.
Using the wrong lubricant may cause the all-wheel drive system to malfunction and cause errors to appear on the instrument panel. Viscosity characteristics oils must strictly comply with the requirements of Nissan engineers. Check the packaging for the approval specified in your vehicle's service book.
Oil volume in transfer case Murano Z52 is approximately 0.8–0.9 liters. To replace, you will need to purchase 1 liter of liquid, since residues may remain in the system or spill when drained. Also prepare a set of tools: a wrench for the drain plug, a funnel, a syringe or pump for pumping oil, and a container for waste.
Preparing the car for the service procedure
Before starting work, ensure that the vehicle is in a safe and comfortable position. Nissan Murano Z52 has sufficient ground clearance, but to access the transfer case drain plug it is best to use a lift or ramp. If such equipment is not available, you can use a jack and safety stands.
The car should be parked on a level surface, and the engine should be turned off and slightly cooled. Working with hot oil is dangerous due to the risk of burns. Clean the area around drain and fill plugs from dirt and dust to prevent abrasive particles from getting inside the transfer case.
Don't forget to prepare rags and gloves. Oil that gets on the skin is difficult to wash off and can cause irritation. It is also worth checking the condition of the drain plug in advance: if the thread is torn or the O-ring is worn, spare plug should be on hand.

Step-by-step instructions for changing the oil
The replacement process consists of several sequential steps that require care. Start by unscrewing the filler plug. This is a critical step: if you first remove the drain plug and the filler plug is stuck, you risk running out of oil in the system.
After making sure that the filler plug can be unscrewed, proceed to draining the old oil. Place a container under the transfer case and slowly unscrew the drain plug. Let the oil drain completely within 10–15 minutes. Pay attention to the color and presence of chips in the drained liquid - this is an indicator of the condition of the components.
After draining, clean the magnet on the drain plug from any metal suspension and install it in place, first replacing the O-ring. Tighten the plug to the recommended torque to avoid stripping the threads. Next, pour new oil through the filler hole until it begins to flow out.

The nuances of checking the level and topping up
Checking the oil level on Murano Z52 carried out along the lower edge of the filler hole. When you add fresh oil, it should flow out of the hole in a stream or drops. As soon as the flow stops and the oil begins to leak only slightly, the level is considered optimal.
If you overfill the oil, it will leak through the breather or seals, creating dirt and the risk of moisture getting inside. Don't overfill excess fluid. After completing the work, be sure to wipe all surfaces of the transfer case and driveshaft dry.
Screw in the filler plug with the new seal and tighten it with a wrench. Make sure the plug is tight, but do not use excessive force. Leak test carried out immediately after completion of work and after 100 kilometers.
What to do if the plug does not unscrew?
If the plug is stuck, try using a penetrating lubricant (such as WD-40) 15-20 minutes before unscrewing. You can gently heat the plug with a hair dryer, but do not overdo it so as not to damage the seal. As a last resort, use an extension wrench, but be very careful not to strip the threads.
| Parameter | Meaning | Note |
|---|---|---|
| Oil volume | 0.85 l | It is recommended to take 1 liter |
| Liquid type | ATF Matic S | JWS 3309 Specification |
| Drain tightening torque | 40–50 Nm | Use a torque wrench |
| Filler tightening torque | 40–50 Nm | Replacement of the seal is mandatory |
| Replacement interval | 60,000 km | In severe conditions - more often |
⚠️ Attention! It is prohibited to operate the vehicle with an oil level below the permissible minimum, as this will lead to rapid overheating and destruction of the transfer case bearings.
Typical mistakes when servicing the transfer case
Often owners Nissan Murano Z52 make the mistake of using gear oil (GL-5) instead of automatic transmission oil (ATF). This radically changes the properties of the lubricant and can lead to failure of the clutch. Never mix different types of liquids, even if they appear similar in color.
Another common mistake is ignoring the condition of the O-rings. Even if the plug appears intact, the old ring may not provide a tight seal, causing a leak. Always change gaskets at every oil change. This is a small thing that will save you from problems with fluid levels in the future.
Improperly tightening the plugs can also cause problems. Too little tightening will cause a leak, and too much will cause the threads in the transfer case to break. Repairing threads in an aluminum case is a complex and expensive procedure. Use a torque wrench for precise tightening.
Before starting work, take a photograph of the location and tightening torque of the bolts on the transfer case if there are any doubts about the correct assembly after servicing.
