What is the best way to maintain my Toyota Land Cruiser's off-road capabilities?

I've recently bought a Toyota Land Cruiser and I love taking it off-road. However, I've noticed that after a few months of driving, its off-road capabilities seem to be diminishing. What can I do to keep my Land Cruiser running smoothly off-road for years to come?

Regularly check and replace your Land Cruiser's air filter. A dirty air filter can significantly decrease engine performance, especially when off-roading. Make sure to replace it every 15,000 miles or so.

Clean and lubricate all moving parts under the car. Mud and dirt can easily find their way into your Land Cruiser's joints and cause them to rust, ultimately leading to poor off-road performance. Regularly clean and apply grease to keep everything running smoothly.

Invest in a good set of off-road tires. Standard street tires are not designed for off-roading and can easily get punctured or wear out quickly. Off-road tires have deeper tread patterns and are made of tougher rubber to handle rough terrain.

Don't forget to check your Land Cruiser's suspension. The constant jolting and bouncing on rough terrain can easily damage suspension components. Have a professional check and replace any worn out parts to maintain a smooth ride while off-roading.
