4WD (four-wheel drive) typically offers a part-time system, meaning you can switch between 2WD and 4WD. AWD (all-wheel drive) is usually full-time, automatically sending power to all wheels. 4Runners offer both, with some models having full-time AWD and others having part-time 4WD.

Can I drive in 4WD on dry pavement?

Generally, no. Engaging 4WD on dry pavement can cause binding in the drivetrain and lead to damage. Use 4WD only on loose surfaces like dirt, gravel, or snow.

How often should I change the transfer case fluid?

Follow the manufacturer’s recommendations, usually every 30,000 to 60,000 miles, or as specified in your owner’s manual. Regular fluid changes are crucial for the longevity of your 4WD system.

What are some common 4WD problems?

Common issues include transfer case leaks, difficulty shifting into or out of 4WD, and unusual noises. Regular maintenance and inspection can help prevent these problems.

Can I lift my 4Runner and still use 4WD?

Yes, you can lift your 4Runner and maintain 4WD functionality. However, you might need to adjust or modify components like the driveshaft or CV axles to accommodate the lift. Always consult with a qualified mechanic when making modifications.
