How many liters of rear axle oil should be added to a Prado?

Prado rear axle oil requires 2.5 liters. Here is more information about the rear axle of a vehicle: 1. The rear axle of a vehicle refers to the axle at the rear of the car. For front-wheel-drive vehicles, the rear axle is simply a follower axle that only serves a load-bearing function. Generally, there is also a transfer case in front of the rear axle. 2. Depending on the suspension of the axle, it can be divided into two types: solid axle and independent axle. Solid axles are paired with non-independent suspensions, such as leaf spring suspensions, while independent axles are paired with independent suspensions, such as MacPherson suspensions. 3. Based on the function of the axle, it can be categorized into drive axle, steering axle, support axle, and steering drive axle.
I've worked on quite a few Prados, and the rear axle oil capacity is usually around 1.2 to 1.8 liters, depending on the model year. For example, the 2010 model uses slightly less, about 1.5 liters, while newer models are more precise and may require around 1.8 liters. When I handle it myself, I first drain the old oil thoroughly and clean it completely, then slowly pour in 1.6 liters of standard GL5 gear oil using a funnel, while checking the oil level hole to ensure it just reaches the overflow line. Don't pour too much at once—overfilling can cause oil to spill and contaminate other components, as well as damage the seals. After adding the oil, take the car for a test drive of a few kilometers and then recheck the oil level to avoid noise or overheating issues. Remember, different regional versions like the Middle East edition might have slight variations in capacity, so the owner's manual is a must-read to avoid small savings leading to big problems.
Last time I changed the rear axle oil on my Prado myself, I measured out about 1.5 liters according to the official manual. In practice, I used a universal gear oil container with gradations to add it bit by bit, and ended up using 1.4 liters. I recommend DIY beginners prepare an oil drain pan, wrenches, and a hose, then slowly pour the oil through the bottom drain plug. Checking the oil level isn't difficult - just use the dipstick to reach the marked level. Adding too little can wear the gears, while adding too much may cause leaks and strange noises. Changing it every 2 years or 40,000 kilometers is most cost-effective. Choosing the right SAE75W90 viscosity oil can extend the differential's lifespan, saving money and giving peace of mind.
