1978 Cherokee Chief

Hello IFSJA,

My name is Sarah and I have a 1978 Cherokee Chief Levi's Edition, 401 w\ turbo 400 trans ( prob a Dana 44 axles front and rear) GM column. A duraspark ignition. With a 4" lift and 35" tires. I got it as a project car for myself.. (my 1st one) and my husband will not help me with it. I know it can be a lot of work for him to teach his wife lol but I think he is jealous ( he has a 1984 Ford F150) so I am asking for help from the fellow Jeep Lovers... What else would be on this model? Stock Gears? what would I need to run 35's? and what jets would I need to run for good Gas Mileage? Now I am a Noob and need lots of help and a lot of layman's terms.

Thank you
Sarah

Welcome from Boston, Sarah.

I suggest you get the factory service manual for your Jeep. It's available online as a reprint lots of places http://www.bjsoffroad.com/prod-673.htm (BJ's will give you a modest discount as an IFSJA member).

Then read everything you can about the Quadratrac transfer case, including the tech library here, the Jubilee Jeeps web page, and old posts here. http://jubileejeeps.org/quadratrac/

To run 35s, they need to clear the fenders. Not sure if 4" of lift is enough for a Wagoneer. You may have to do some fender trimming, or go to a smaller tire. Others here will comment on this.

A 4" lift and 35" tires should be fine, stock gears are hard to say as the there were options, best way to find out is to check the tag on the front/rear diffy.
As far as what would be the best gears, it depends on how you plan on using it, rock crawling, mud bogging, and Daily driver all have different "best" choices.
Best guess it would have 3.54 gears stock, but it could be higher or lower. (most I have seen stock have been 3.54's) 3.54's should be fine for most use kicking around, too high for rock crawling, to low for best milage on the freeway.

As far as jets go, hard to say , depends on altitude and state of the rest of the tune.

Tune it to stock specs, and go from there.

Sarah,
welcome from AZ! I am up in Gilbert. Did you see the Meet-n-Greet this coming weekend down your way. Would be a good time to make a lot of contacts.

As for your questions, My jeep is running 35's and I run 4.10 gears. It all depends on the amount of highway driving you do and whether or not you tow. I know Willie is running 35's with his 401 Cherokee and he runs 4.56. With 4.10's I can run all day long at 70-75 mph down the highway. I too have a TH400 and fulltime Quadratrac. If you don't mind driving a little slower on the highway, I would recommend 4.56. If I had to do it over again, that is what I would do as I mainly use the jeep for wheeling and towing, a little more gear would be nice.

If your jeep is stock, I would venture to say it has low-pinion (standard rotation) Dana 44s front and rear. Being a TH400 Cherokee, I will assume it has a Quadratrac transfercase. I will also assume the rear axle differential is offset to the passenger side. Gears are most likely 3.54-1 if they are stock. Easy way to check, lift a axle/tires off the ground, rotated the tires one full revolution and count the number of times the pinion yolk rotates. 3 1/2 turns will be 3.54-1 gears. Just over 3 turns will be 3.07-1 gears.

If you end up needing any help with the Quadratrac, just send me a pm, I have the Miller Tool Kit for the Quadratrac and would be happy to help you with it.

Welcome to IFSJA!
Kevin

Welcome Sarah, of course he's jealous.
I pm'd you the info/links to the WOT & M&G tomorrow and Sun.
make it to one of those and you'll have a whole bunch of talent ready and willing to walk you through any aspect of what it takes to own/build/work on and wheel one of these rigs.

Except for the gas milage thing, 35's = 10-12
Anything better than that and you are doing great.

Welcome from CT.

Everyone here will be glad to help make your husband jealous. However, many of us are going to be jealous that some guy has a jeep-loving wife when many of us get griped at by our wives because of our Jeeps. Sigh...

One more thing though:

Nice Jeep Sarah.

Looks like your dog is a bit camera shy though.

Just so ya know...Jeep didn't do that with the floor pedals
Some of the interior has also been modified ie centre console etc.

Technically, I think it is probably a Cherokee 'S' Wide Axle.
The "Chief" usually had the full length decal saying "Chief" down at the bottom of the door and across the tailgate. The "S" had the stripe you have with "Cherokee" at the front and a large round Indian Chief with a small "S" at the bottom of it and mounted on the 'C' pillar where yours is. Actually the "Indian" was common to most variants.

Wooooa....what is THAT!

An amazing set of instruments for the 'flight engineer' over on the right side of the dash.

I can hardly wait to see the fotos for the 'navigator's ' position.
AND the bombardier's position is likely equally as

Nice Jeep though...and a 401 !!! to die for.

Since you're new at this, you should know that those 401s like you have are horrible engines. They're prone to blowing up, and that's why they quit making them some time back.

I'm willing to trade you a much better, more refined 360 for your time bomb 401.

I'll even do the labor. Just let me know when to come by.....

What an awesome looking Cherokee! My favorite color and stripe package!!! Welcome. Looks like you have some kind of add-on heater or A/C mounted under the dash near the CB. Factory A/C was a plastic vent system that bolted to the bottom of the dash but took up the whole width of the space from door to door.

So why isn't it running right now? Does it turn over or just run poorly?

Well it runs poorly, not sure of RPM at idle. when I drive it around the block it guzzles gas like no tomorrow. turns over nice and the timing set up. Purrs like a kitty.... I replaced plugs, wires, did oil change, replaced air filter, and driver side window regulator on my own as well as door locks and ignition and sea-foamed it too.

What else would I need to do to get the carb to run better?

I know going down to a stock tire size may help a little, but what can I do in the mean time?

I would like to get my Jeep to be a daily driver. good thing I only drive 8 miles to work lol

Beautiful Cherokee S. If you polish that thing it's going to come back as shiny as it was when new!

From the pics I see a very nice thing in this rig, it has locking hubs at front thus meaning that it might have received a part time conversion in the transfer case at some point.
Check if they are set to be "free" or "4x2" and then also check to make sure that the knob in the glove box compartment is not set to Emergency drive (the red part anyway) and this because sometimes people thought that by just installing manual locking hubs they could increase their gas mileage but then they realized that without the front traction the jeep would not move unless they were actually locking the central diff (that is in your tranfercase).
The kit for the conversion actually came with a sticker that was supposed to be applied on the the metal plaque behind the knob in the glove box therefore it might actually be there. In that case on the left side it will now say "two wheel drive" while on the right side it will obviously say "Four wheel drive".

I would give rid of the 35s and get a set of 33s. Too bad that they installed those stupid rear view mirrors that are half way down the doors...But for sure a very good looking Cherokee!!
