Jeep TJ Wrangler NP231 Transfer Cases

Make Sure It Fits Your Vehicle

Accelerating over rough trails makes your heart race in exhilaration, but hearing strange noises when you shift gears makes your heart plummet. Fixing and replacing parts like a 1998 Jeep Wrangler transfer case doesn't have to break the bank. Turn to 4WD.com to supply you with the best aftermarket Jeep parts for affordable prices.


 What Is a Transfer Case?
A 2002 Jeep Wrangler transfer case uses drive shifts to help move power from the transmission to both the front and rear axles. This allows your Jeep to climb steep inclines and power over rough off-road trails. The axles must move right in order for your wheels to grip the terrain correctly for you to have successful off-road adventures.

When Does the Transfer Case Need To Be Replaced?
You love slinging up mud and debris while riding off road, but when the gear shift starts sticking, you can't shift gears the way you need to. You hear strange noises when you manage to force the gear shift into position, and you know something is wrong with your Jeep TJ transfer case.


At 4WD, we have the best replacement transfer cases for you. Our helpful diagram helps you to determine exactly which Jeep Wrangler transfer case you need. We know that you don't have the time or money to waste on inferior parts that can't keep up with your rough off-road adventures, so we offer you only trusted brands like Crown Automotive and Omix-Ada to guarantee you quality parts that last.


4WD focuses on creating lasting relationships with other jeepers by provided them with high-quality parts for a fraction of the standard cost. We are so dedicated to having the lowest prices that we have a great price matching policy. If you buy a 1997 Jeep Wrangler transfer case from us and then find a better price within 90 days, we will be glad to match that price and give you the difference back. Don't wait any longer to find affordable parts to beef up your ride. Shop with us today.
