Jeep XJ Cherokee NP231 Transfer Cases

Make Sure It Fits Your Vehicle

J Cherokee NP231 Transfer Case
Fire roads are an excellent way to get started off-roading, but primitive motor trails and slickrocks take the adventure to new heights. If you are active off-road, even if it's occasionally, your Jeep is taking a beating. Understanding upgrades and maintenance requirements enhance performance and keep it out of the garage.

Common Issues
4WD High are the gears used for everyday driving. The fun starts when you get off the pavement and shift to the low gears. 4WD Low is for low speeds and high traction. It's all about the torque and the gearing of the NP231 transfer case. These gears punch up the power for rock crawling and two-wheeling. Significantly enhance off-road performance with the right tires. Rock tires and mudders are great on the trail but don't hold up on the black top. For optimal performance match the lift to tire size. Going too high can cause stability issues, and the axle strength limits the tire options. 


Drivetrain vibrations occur in lifts over two inches because the driveline angle is too much. Fix part of the problem with the upgrade of a longer drive shaft and a slip-yoke eliminator. The decreased drive shaft angle reduces the stress on the output shaft. Check the model requirements and specifications before you upgrade. The 1994 Jeep Cherokee transfer case has few crossover options, but can be rebuilt.


Axlewrap causes damage in rigs with a shorter wheelbase. Lowering the Jeep XJ transfer case can help, but then you've lost the lift advantage. An aftermarket 1998 Jeep Cherokee transfer case and high-quality replacement parts improve performance and are durable. Maintenance checks and preventative measures after each trail ride reduces the chance of breakdowns.

Maintenance Checks
Even upgraded aftermarket parts are pushed to the limit with regular off-road trips. Check the transmission, differential, axle and shocks for cracks, leaks and dents before serious damage occurs. Premium parts enhance the ride and improve longevity. At 4WD.com, we source from quality manufacturers, so you know you are getting the best parts for your off-road experience. Place your order today and get started on the next adventure.
