First off, wow.

Now, lets start to understand what you are asking. If it has a V8, then somebody swapped that in. So, what t/case is in there? I can't image you will spin all 4 tires in 2wd. So iether it isn't in 2wd, or you have an odd t/c in there. And the front axle is a Dana 30, not a dyna 35. There are hub kits for it (made by Warn) but it is much $$$.

If one tire up front and one in the rear are spinning when you step on the gas, that means the front and rear are locked... as in it's in 4WD, most likely 4Hi. Just because the little shifter says it's shifted into "2WD", doesn't mean it is IN 2wd.

Get that shit looked at by a competent mechanic.

You don't seem to be understanding what people are trying to tell you. If there is power going to the front wheels IT IS NOT IN 2 HI The shifter may be in the 2 hi position, but it theres power going to the front wheels it has to be in 4-something.

The NP207 was used in the first year of Wranglers in 1987.

The NP 207 is one of the weaker Jeep transfer cases, but can be upgraded. The NP 207 has an aluminum case and chain driven planetary reduction. Thankfully the NP 207 was installed behind some of the weakest Jeep power trains every used. It featured a 2.60:1 low range and a straight through design high range, but featured a driver side front output. It was used in one year of the Jeep YJ Wrangler 1987, and in the early XJ Cherokee's from 1984-1987

The NP207 was used in the first year of Wranglers in 1987. It was used in Cherokees (XJ) until from '84-'87 and replaced with the NP231.

I found one page with conflicting info, but since it agreed with you, I left it out.:tonka:

Crawl underneath, disconnect shift linkage from tcase. Manually shift tcase into all ranges, see if that works. If so, linkage is not adjusted. Adjust accordingly.

oh, and put it in 2wd and spin front driveshaft.
