What You'll Learn
Removing the front axle
To remove the front axle of a 2006 Nissan Pathfinder, follow these steps:
First, jack up the front end of the vehicle to take some weight off the front wheels. It is important to note that you should not lift the vehicle all the way off the ground. Use jack stands to support the vehicle and ensure your safety. Next, remove the caps that cover the ball ends of the radius rods. With the weight off the front end, you can now swing the radius rods away from the sides of the trans case.
For the drag links, it is recommended to remove the front ends first. This will allow you to rotate them back and rest them on the rear axles. Now, you can focus on detaching the front axle assembly. To do this, you need to remove the 4x4 hub assembly. Once the 4x4 hub is off, you will find a snap ring. Remove this snap ring, and then proceed to remove the lower ball joint bolts.
At this point, you can push the knuckle out and slip the axle out after unbolting it from the differential. It is important to note that you are accessing these bolts from the side, not from underneath the vehicle. Additionally, be cautious when handling the CV joint, as it may require some force to knock it off the axle.
Finally, with the axle removed, you can access the oil pan for inspection, repair, or replacement. Remember to follow any additional manufacturer instructions or guidelines for your specific vehicle model.

Lifting the engine
First, it is important to understand why lifting the engine is necessary. The oil pan is located at the bottom of the engine, and to access it, you need to create enough space to work comfortably. Lifting the engine provides the necessary clearance to remove the oil pan. It is also important to note that the Pathfinder's engine is quite heavy, so a proper lifting setup is essential.
To begin the process, you will need to gather the required tools and materials. An engine hoist is highly recommended for this task, as it provides a safe and controlled way to lift the engine. Additionally, you will need jack stands, a jack, and a piece of wood or plywood. The wood will be used to support the engine and protect it from damage during the lifting process.
Before lifting, make sure to loosen the support mount nuts and any relevant bolts. This includes the top bolts on the motor mounts, as well as the bolts holding the oil pan in place. You may also need to remove certain parts, such as the starter and some lines, for better access. Once everything is loosened and removed, you can start jacking up the engine gently.
Place the jack underneath the engine and start lifting it slowly. Use the jack stands to support the weight and ensure the engine is stable. As you lift, be cautious of any lines or components that may be in the way, and adjust them as needed to avoid damage. Continue lifting until the engine is high enough to access the oil pan.
Once the engine is lifted, you may need to unbolt the sump tube and remove the engine mounts to gain better access to the oil pan. This will provide more room to work on the oil pan removal. Remember to take your time and be gentle during this process to avoid any accidental damage to the engine or its components.
By following these steps, you can safely lift the engine of a 2006 Pathfinder to access the oil pan for removal or maintenance. Remember to work carefully, and if you have any doubts or concerns, it is always best to consult a professional mechanic.

Removing the oil pan with the motor still in the car
First, make sure your Nissan Pathfinder is parked on a flat surface and engage the parking gear. It is important to block the rear wheels to keep them stabilized during the process. Next, drain the oil by placing a drain pan under the engine and removing the drain plug on the bottom of the oil pan with a wrench. Once the oil has drained, replace the drain plug.
Disconnect the negative battery cable and remove the following components: the stabilizer bar, front crossmember, starter motor, transmission mount, right and left motor mounts, and power steering gear. You may also need to remove the radiator shroud and loosen the motor mount bolts. At this point, you may need to raise the engine for clearance, using a jack to support it securely.
Now, you can remove the oil pan bolts and then carefully remove the oil pan. Be cautious, as there may still be some oil remaining in the pan. It is recommended to have towels ready to absorb any spilled oil. After removing the oil pan, scrape off the old sealer and wipe the joining surface with an engine cleaner.
If you are planning to reinstall the oil pan, apply a thin bead of liquid gasket to the joining surface and quickly replace the oil pan. The oil pan must be in place within 5 minutes, or you will need to scrape off the liquid gasket and start again.
It is important to note that removing the oil pan with the motor still in the car may require some creative problem-solving. Some people have suggested that you may need to remove additional components, such as the oil sump bolts or the nuts from the motor mounts, to create enough clearance to remove the oil pan. Additionally, some have mentioned that removing the oil pickup or sump tube is necessary to successfully remove the oil pan.
This process can be complex and time-consuming, so it is recommended to set aside a full day for this project and have access to alternate transportation in case of any issues or accidents. Always refer to the factory service manual for specific instructions and safety precautions for your vehicle.

Unbolting the sump tube
First, locate the sump plug and place an oil drain bucket underneath it to catch any oil drips or spills. The sump plug is usually found at the bottom of the sump tube. Once you have found it, try to undo the plug by turning it in an anticlockwise direction. You may need to use a spanner or a breaker bar for extra leverage. If it still won't budge, try saturating the plug with a penetrating oil, such as RP7, and let it sit for about 20 minutes. This should help to loosen any rust or debris that may be causing the plug to seize up.
If the plug is still stuck, you can try to give it some gentle taps with a hammer to crack the thread. Be careful not to use too much force, as you don't want to damage the plug or the surrounding area. After tapping it with a hammer, try again to undo the plug with your spanner or breaker bar. You can also try using a longer tool to get more torque and really put your body weight into it, as if you're rowing.
In some cases, the sump plug may be seized up due to corrosion or damage. If this is the case, you may need to apply more force to break it free. Be very careful when doing this, as you don't want to strip the threads or cause any other damage. It is important to work slowly and methodically to avoid further complications.
Once the sump plug is removed, you can proceed with the rest of the oil pan removal process. Remember to have a plan for the safe disposal of any old oil and to refer to a trusted repair manual for your vehicle if you are unsure about any steps in the process.

Removing the trans
To remove the transmission on a 2006 Pathfinder, you will first need to remove the oil pan. This can be done by following these steps:
Begin by driving the car for 10-15 minutes to warm up the transmission to its normal operating temperature. Then, place the car on truck ramps or jack stands and chock the wheels for safety. Once the car is securely raised, locate the transmission drain plug at the front of the transmission case and remove it using a 3/8" ratchet. Allow all the fluid to drain out.
Next, remove the bolts securing the transmission pan, being careful not to snap any bolts. Depending on the model of your Pathfinder, there may be brackets for the cooling lines attached to the bolts, so take care when removing them. With the bolts removed, the transmission pan should come off. Clean the old gasket from the pan and refill the transmission with fresh fluid.
Now, to remove the transmission itself, you will need to:
- Remove the crossmember by loosening the bolts and lowering it. This will give you more space to work with and make accessing the rear bolts easier.
- Locate the four bolts holding the torque converter to the flywheel/drive plate/ring gear and remove them. These bolts can be accessed through the starter hole.
- With the bolts removed, carefully lower the transmission and tilt the engine to gain better access to the remaining bolts.
- Remove the remaining transmission-to-engine bolts. You may need to lower the front of the assembly to gain better access to these bolts.
- With all the bolts removed, carefully separate the transmission from the engine.
