1990 Jeep Cherokee XJ - 4xForum

Tail Spin
Am I the only guy with an '87 Wrangler with a 207 transfer case? I want to do a tailshaft conversion, but I can't find anyone who does it for the 207. Any ideas? Barring that, what's involved with swapping to a 231? I just had a Peugeot tranny installed too.

Billy,
Actually your T-case could be a 229 or a 207. The 229 should have a shift slider knob between the seats. As far as we know, you don't have any options for a tailshaft conversion, but you can try calling Rubicon Express (916-858-8575) since its kit only modifies the existing tailshaft. It just might fit your application. A 231 swap can be done, but you'll need all the parts from a later Cherokee to do it.

Tire Fitment
I really enjoyed your article on the new MT Baja Claw. I have a '90 Jeep XJ with a 3-inch Rancho lift and MT MTX 31x10.50 tires. I plan to purchase a new set of tires, and your article seemed to answer most of my questions. I would like to know what lift was used on the XJ, the size of the rims, and whether there was any wheel rub with the 31x11.50 tires. I have been a subscriber for at least 10 years now and enjoy every issue. Keep up the good work.

Ed,
We can't tell you the exact information on that Cherokee, but we can tell you that we've been able to fit 32x11.50R15 tires on a Cherokee using a 4-to-5-inch lift and 8-inch rims with a 3-1/2 to 3-3/4 backspace. You will have some rubbing in full turns with suspension compression, but this can be reduced by trimming the fenders slightly and banging flat the sharp lip at the back of the wheelwells.

Fuel-Injection Fix
My name is Linus and I live in Switzerland. I have an '86 Jeep CJ-7 equipped with a 304 AMC V-8 and an Edelbrock intake manifold, and I want to upgrade it with a fuel-injection kit from Holley. Holley makes a kit for this motor, but since the specifications are not complete and my intake manifold is not original, I wonder if I need an adapter to fit the fuel injection to the intake manifold or others accessories. Can you please help me?

Linus,
The Holly fuel injection should fit as long as you get a base adapter to mate the Projection throttle body to the manifold. This shouldn't be a problem for Holley. The company has several adapters available. For more information, contact: Holley, (270) 782-2900, www.holley.com.

Who Made What?
I have been an avid four-wheeling enthusiast for a number of years. I have also subscribed to all the four-wheel-drive magazines and have been a Ford man since I was knee high to a grasshopper. In the 4xNews section of your September 2000 issue, you show a picture of a white 4x4 truck with the title "GM to Introduce Four-Wheel Steering." That truck is not a GM product. It's a Ford F-350 with four-wheel steering. Come on guys, how dumb do you think we are? Did you think we would let this slip by unnoticed?

Jess,
You're right. The truck you saw is a Ford. We noticed this and made a call to our freelance writer and found out that Delphi is the contractor for both Ford and GM on the four-wheel steering systems. While GM will be going to market first, Ford is also looking at the system. Spy shots such as this are often done as able, and this time we could only get a photo of the a system on the Ford. We were really focusing on the rear steering, not the truck it was on. Good catch.

Need A Boost?
I saw an ad in your magazine a few months ago that I think was in the new products section. It was for a small, but powerful brake booster.When I swapped the ailing Carter for a throttle-body fuel injection, the only air filter offered for the kit rubs against the booster. It needs replacing anyway, so this would kill two birds. I have looked through stacks of the best magazines on the planet, but can't find the ad. I was hoping someone might know, or you would have an easy way to find the information for me without going through a lot of trouble. Thank you very much.

Mark,
The booster you are referring to is the Navajo Brake Booster from Off Again in Farmington, New Mexico. The company can be reached at (505) 325-5761. If you can find your June 2000 issue, it is on page 97.

Carburetor Woes
I'm having trouble with my '78 CJ-5 and was wondering if you could give me a few ideas. I purchased my CJ-5 with a '69 327 conversion. While 'wheeling steep hills, the engine shuts down. When restarting it, I have to hold the gas pedal to the floor, and when she starts, black smoke comes from the exhaust. It has a four-barrel Holley carburetor, but I'm not sure what kind. What's up with this?

Bob,
It sounds like your carburetor float is out of adjustment. You may also need a new needle and seat. Have your local shop take a look at the carburetor and see if they can rebuild it with some of Holley's off-road service parts.

In Need Of A Guide
I've been searching local bookstores for some off-road guides, but without much luck. Can you point me to a source that sells or publishes off-road guide books? Specifically, I am looking\ for information on Texas, Oklahoma, Arkansas, and Louisiana. I would like to get some recommendations on off-road trails, tours, even group outings. Please let me know if you have any information that might point me in the right direction.

Matt,
There are a number of publishers and retailers that offer off-road guide books to destinations across the U.S. Those listed below comprise just a brief list, and we're certain each of them will be able to give you other avenues to pursue as well.

The Fact Of The Matter
I was shocked and amazed by Rick Russell's article on the Dana 300 transfer case. The first paragraph turned my stomach and made me think I was reading a Petersen publication. "The factory transfer case used in CJs from '80 to '86 was one of Jeep's better creations."

I'm sure I do not need to tell you that Dana is not part of AMC and that my International Scout does not have an AMC transfer case. Please try to do a better job with the facts. There are many younger 'wheelers who do not know any better.

You are correct, Dana Corporation did design and build the Dana 300 in addition to the earlier Dana 20 and Dana 18 T-cases. All were used in Jeeps and Scouts and even a few other vehicle types. While Jeep didn't create the Dana 300, it did use it extensively, so perhaps the correct usage should have been that it was one of its better decisions.

By the way, as a Scout owner you know that the Scout Dana 300 was a special unit that bolted to the Dana 20 bolt pattern used by both Jeep and Scout. The Jeep Dana 300 used a round bolt circle instead. Also the Scout Dana 300 was used in only the last of the Scout II production run right at the end of 1979 and all throughout 1980.
