- ZJ Grand Cherokee NP231 Transfer Case
Jeep Grand Cherokee ZJ NP231 Transfer Cases
Make Sure It Fits Your Vehicle
Since 1988, the NP231 has been the Command Trac transfer case used in Cherokees (XJ), Comanches (MJ), and Wranglers (YJ). It has been the Command Trac transfer case in the Grand Cherokee (ZJ) since its introduction. The new Wrangler (TJ) continues to use the NP231. 1987-95 YJ and 1997-04 TJ Wrangler rear of case has circular I.D. tag. Tag has model number, assembly number, serial number and low range ratio. Some 1987 Wranglers came with NP207. Your ZJ transfer case is a hardworking, durable and powerful piece of art. Designed to transfer power from your transmission to your drive shaft, your transfer case makes it possible for you to cruise smoothly in four-wheel and all-wheel, both on the road and off. If your transfer case takes a dive on you, you're SOL, and while your friends are cruising through the muck, you'll be sitting in the garage waiting on some good news. Don't play the waiting game, and replace your transfer case with a durable, aftermarket replacement part from 4WheelParts.com.
How to Tell if Your Transfer Case Has Gone Bad
A bad transfer case is a wild card, and the symptoms of a failing case can vary significantly. Some jeepers claim that it becomes difficult to shift gears, while others report a high-pitched squeal or other unusual noises. However, one common symptom is the random shifting of gears mid drive. If you're on the road and go from 2 high to 4 low without shifting gears yourself, chances are your transfer case is turning bad and that it's time for a replacement.
