What model of rear axle oil should be used for the Crown?
3 Answers
The model of rear axle oil for the Crown is GL-585W90. The rear axle of a car refers to the rear axle of the vehicle. For front-wheel-drive vehicles, the rear axle is merely a follower axle, serving only a load-bearing function. Generally, a transfer case is also equipped in front of the rear axle. The working principle of the car's rear axle is as follows: 1. The engine transmits power to the transmission, which then transfers it to the large gear plate of the rear axle. 2. The differential is an integrated unit, consisting of: upper and lower small gear plates with a cross-shaped column in the middle, on which two small planetary gears are mounted. 3. The differential is positioned vertically, with two small circular holes on either side and sliding keys on top. When driving straight, the cross-shaped column remains stationary; during turns, the cross-shaped column moves to adjust the rotation speed of the tires on both sides, thereby enhancing the vehicle's maneuverability during turns.
As an experienced car enthusiast, I often help friends with similar issues. For the Crown's rear axle oil, GL-5 grade gear oil is generally recommended, such as 75W-90 or 80W-90 viscosity. It's crucial to choose the right one because the differential operates under high loads, and using the wrong oil can accelerate gear wear, even causing noise or failure. I personally used Castrol Syntrax GL-5 75W-90 in my 2018 Crown, and the results were excellent—noise was significantly reduced. Remember, different model years may have variations; for example, older Crown models might lean towards 80W-90, while newer ones prefer synthetic oil. Always check the user manual or consult a dealership to confirm—don't just rely on others' advice. The replacement interval is roughly every 40,000 to 60,000 kilometers, as the oil degrades over time, affecting performance. Regular maintenance can save you a lot of money—rear axle repairs aren't cheap. If you're doing it yourself, find a level surface first—safety is the top priority.
I've been driving a Crown for several years and learned some lessons the hard way with rear axle oil. Generally, GL-5 gear oil works fine, with 75W-90 being the most common - affordable and practical. I chose Mobil 1's 75W-90, and after changing, shifting felt smoother with less vibration. Why emphasize this? Because the Crown's rear differential is sensitive to oil - too low viscosity means insufficient lubrication, while too high increases fuel consumption. Don't skimp on this small expense; you can get a good quality bottle online for just tens of yuan. If unsure about your specific model (older Crowns may have different requirements), take a photo of the manual and ask a repair shop. Personally, I change it every 50,000 km to maintain rear axle health and extend vehicle lifespan. The key is to check oil level before working to ensure no leaks. Overall, choosing the right oil type and brand brings greater driving peace of mind.
