Does it have 4wd part time and full time? if so it's np242, otherwise np207. The NP208 was used in the SJ's. The other command trac used in the xj's, but later, I think, was the NP231. john At 09:06 PM 3/9/02 -0600, The Ferminator wrote: >John, > >I checked my XJ (1987 Cherokee Pioneer) and apparently I have a Dana 30 >(front) and Dana 35C (rear).

But I'm wondering if it's the tool or the supply of air. It's supposed to develop 350 max and 200+ working, but it would comlpetely stall on bolts it took no more than 150 measured by hand to undo. I am likely going to try and return it for refund, and by the IR big gun. But I'm wondering, is their a way to test my air supply, just to see if it's delivering the required flow / pressure. The reg is cranked and shows 100+ psi, tool running. Hose is Rubber 3/8", 50 ft. Bill ------------------------------ Date: Sun, 10 Mar 2002 11:36:52 -0600 From: "Bill Hart" Subject: xj: Got it Just wanted to let you guys know we did end up purchasing the 84 Cherokee Chief (2.5 auto). It had some patches on the body that are aging, and it doesn't run well at all, but the underbody is nearly perfect and the interior only has a couple rips in it, so we decided to go for it. The big problems that we need to take care of right away are the exhaust is EXTREMELY loud, either a cracked manifold or a missing exhaust doughnut (former owner claims doughnut is bad). The other problem is it can't really be driven, it seems to idle okay (though a bit loud ;) but as soon as you step on the gas it boggs down, tries to go and seems to flood out (putting it back in neutral and revving it up clears it out again) ... the guy claims the carb needs total replacement/rebuilt, but I'm wondering if it might be something simple that happens to these a lot as it has happened before too ... anyone got any insight on this ? Obviously we'd like to get it up and running as soon as possible so we can start enjoying it even more.

It might be plugged and a enough fuel is passing through for idling, but when a load is applied the engine might be able to get enough fuel. Just a thought that would be cheap and easy to start with. anyone know of signs that an oxygen sensor is going bad or is bad. My 88 cherokee is suffering from poor mileage. It sometimes idles rough after I come to a stop.

I have the 2.5 with the Carter that they told me was leaking. I went to another garage and had them put on a rebuilt one, but it also had a leak. So, for under $400, I got the Weber. I have no idea how well a brand new 2.5 runs, but there is definitely night and day difference between what I started with and how peppy it is now. Unfortunately the Tune-Up Masters became an apartment complex and the Weber needs some fine tuning, but unless you convert to fuel injection, this is a much better way to go than rebuilding or replacing the Carter. As for now, I would replace all fluids, filters, and check all hoses - especially vacuum lines. From there I would start at the rear and work forward. By that, I mean get the exhaust done first - a nice low restriction system - especially if you have to replace the catalytic converter (I never heard of a doughnut - is that a reference to the cat?). It ended up that I also had a bad transmission that was causing major problems with it's ability to run right. I kept blaming the carburetor because mine only had 85,000 miles on it, but after the transmission was rebuilt, it was a major improvement - it's so much fun, though in about a year or so, I will be looking for a 4.0. Just have to get my money's worth out of this one first.. ------------------------------ Date: Sun, 10 Mar 2002 18:55:41 -0400 From: "samfans" Subject: Re: xj: testing shop air supply Yea, the IR 2131 is a pricey unit, but I've never seen any tool so universally recommended. First, I'm goint to replace my filter and regulator from $20 units to $80 units by IR. And I'm going to remove the extra in-line water seperator (cheapie) and cut back from 50' of 3/8" hose to 25'. Might as well give the tool all I can to start. I do like the comfort and smoothness of the tool....

I don't have one on my '93 2.5L. I would bet that the exhaust manifold gasket is blown out. As far as the lack of power when accelerating, what kind of condition is the catalytic converter in?
