What Transfer Case is in a Jeep Yj?
The Jeep YJ came with two different transfer cases. The NP207 and the NP231. The NP207 is a part-time, chain-driven transfer case.
It has a 2.72:1 low range and a 1:1 high range. The NP231 is a full-time, chain-driven transfer case. It has a 2.72:1 low range and a 0.87:1 high range.
How Do I Know What Transfer Case I Have in My Jeep?
If you’re not sure what transfer case is in your Jeep, don’t worry – there are only a few types that were used over the years, and it’s easy to identify which one you have. The most common type of transfer case in Jeeps is the NP231, which was used from 1987-2006 in Wranglers and Cherokees. If your Jeep has this type of transfer case, it will likely have a 23 spline input shaft and a 21 spline output shaft.
Other types of transfer cases that were used in Jeeps include the NP207 (used until 1986), the NP228/229 (used from 1988-1998), and the NV242/249 (used from 1999-present). To identify which transfer case you have, simply look for a tag or sticker on the unit itself – it should list the model number. You can also check your Jeep’s service manual to find out which type of transfer case was originally installed.
Are All Jeep 231 Transfer Cases the Same?
Are all Jeep 231 transfer cases the same? No, they are not. There are three different types of Jeep 231 transfer cases: the Full-Time, the Part-Time, and the Selec-Trac.
Each one is designed for a specific purpose and has different features. The Full-Time transfer case is designed for use in both on-road and off-road conditions. It has a constant engagement between the front and rear driveshafts, meaning that power is always being sent to both axles.
This makes it ideal for use in slippery or uneven terrain where traction may be an issue. The Part-Time transfer case is designed primarily for on-road use but can also be used off-road if necessary. It does not have the constant engagement between the front and rear driveshafts like the Full-Time model does, so power is only sent to one axle at a time.
This makes it more fuel efficient but less capable in slippery or uneven terrain. The Selec-Trac transfer case is similar to the Part-Time model but with one key difference: it has a mode selector that allows you to choose whether you want power sent to both axles or just one of them. This gives you more control over how your vehicle performs in different conditions and makes it more versatile than either of the other two options.
Is the 231 Transfer Case Good?
The 231 is a great transfer case for what it was designed for, which is light duty applications. It’s not as strong as some of the other available options, but it’s more than adequate for most Jeepers. There are a few things to watch out for though.
The main thing is the output shaft bearing. This has been known to fail prematurely and can cause all sorts of problems. Other than that, the 231 is a good choice for a budget-minded Jeep owner.
The 1991 Jeep Wrangler came with a transfer case that was designed to be used with the four-wheel drive system. This transfer case is responsible for providing power to the front and rear wheels, as well as transferring power from the engine to the transmission. The transfer case is located under the vehicle, between the frame and the body.
It is connected to the engine via a driveshaft, and it is connected to the transmission via a series of gears. The transfer case uses fluid to lubricate and cool itself, and it also uses fluid to engage and disengage the clutch. The clutch is what allows power to be transferred from the engine to the transmission.
When engaging the clutch, fluid pressure builds up in the system and forcesthe gears in the transfer case to turn.
