Jeep 4x4 System

If you own a Jeep, you’re sure to put its impressive 4×4 capabilities to good use off-road. Along with standard upkeep services, the transfer case, differentials, and other 4×4 system components require specific care to stay in form. Here’s a solid guide to Jeep 4×4 maintenance

Check the Differential Fluid

The front and rear differentials are crucial in delivering power to each wheel while allowing them to rotate at different speeds over any surface or obstacle. The fluid in each differential should be checked periodically and changed every couple of years. Also, check each differential frequently for leaks, especially after a rigorous off-road adventure. 

Change the Transfer Case Fluid

Your Jeep’s transfer case is at the heart of the 4×4 system, sending power to both the front and rear axles. The gears, bearings, and chains inside the transfer case are also kept cool and lubricated by high-quality fluid. As with the differential fluid, check the condition of your transfer case fluid often, watching out for leaks. You’ll need to flush this fluid every two to four years. 

Keep the Tires Properly Inflated

As you take your Jeep over rough terrain, the tires encounter all kinds of pressures and challenges. It’s crucial to keep them at just the right PSI by measuring the air pressure once or twice a month, adding or releasing air when needed. 

Align, Rotate, and Balance the Tires 

The irregular surfaces of off-roading can strain any vehicle’s suspension, which holds the wheels in place. Therefore, the more you take your Jeep off-road, the more frequently you should have your tire alignment checked. You’ll occasionally find that slightly crooked wheels need to be corrected. 

It’s also unwise to allow your tires to wear unevenly, as this shortens their longevity and traction strength. Twice-a-year rotations will typically solve this problem. Additionally, have each of your tires balanced every now and then.

Clean the Undercarriage Frequently 

Driving off-road brings the underside of your Jeep into plenty of contact with mud and water, which heightens the risk of rust. It’s advisable to clean your Jeep after each off-road trip, focusing a good deal on the undercarriage. An anti-corrosion spray will help you combat the onset of rust.
