Axle width for Cherokee's and J-trucks

Not enough time to research so I will ask the minions for any wisdom that can be had....

Is the WT Cherokee the same as the '79 J-10 in axle width and spring pack mounting width? I have a pair of '77 Dodge D60's that were going into the J10 but.....We (the wife) are thinking about jumping from the J10 to a cherokee?

Front is the same, rear is significanly narrower, will have to do a 6 inch lift to get any size tire to work. I am in process of doing this now with a set of j20 axles. the Dodge axles are a bid narrower I believe, maybe someone can be specific

Someone on here (Stuka? joe?) told me the WT Cherokee knuckles are different from the J10 knuckles, giving the J10 a slightly wider track. Certainly the J-truck rear is significantly wider than the WT Cherokee - the J-trucks are one of the few vehicles with a wider rear track than front. Supposedly it's so that a 4' wide sheet of plywood will fit beteewn the wheel houses.

Cherokee WT front is 64-65" wide, WMS to WMS. Rear WT is 60.75" WMS to WMS. This was measured, twice.

I took front hubs, bearings and all, off an '88 GW front and installed them onto my '77 J-10 with no issues. Plug and been playing for 2-3 months.

I don't doubt it, but the TSM does list a wider front track for the WT Cherokees than for the J-trucks: 65.4" v. 63.3". Maybe it's the WT hubs that are different.

I had a set of 92 CTD Dodge D60 axles under my 83 Cherokee, it was pretty much a bolt in deal. Spring pads and width was just fine.

This could be because of the different wheels that are used. The track width spec. in the TSM for the J truck is probably with standard wheels.

IIRC, they both came stock with the 15x8 spoke rims...

Wheels are the same, unless you've got a J-20.

WT's had the widest front axle of all the FSJs, J-trucks had the widest rear axle. The rear frame on J-trucks is significantly wider than waggies/cherks and makes a rear axle swap a little more difficult. Front axles on all FSJs (from 75 on up) are interchangable, width aside.

Proper axle width measurements need to take 2 things into consideration. Perch center to perch center and Wheel Mounting Surface (wms) to wms.

The 15x8 spoke were not stock on the J truck. Those were available with the Honcho, Golden Eagle and 10-4 trim packages. I'm fairly sure these are the same wheels found on the W/T cherokees. Stock for a J truck were plain stamped wheels I think 15x7.

15x8 is the stock wheel for WTs and 1/2 ton J-trucks. Outside of wheel color, the packages have little to do with it.

So to carry this train of thought a bit farther...if I wanted to take a set of axles off, say an 81 J10 and put them under an 80 W/T cherk, I'm looking at what? Sounds like at the minimum moving the perches on the rear axle?

I haven't done any measurements on this yet but this is likely a project I'll be taking on this year.

So, here's the plan. Let me know if you think it won't work.

Cherokee Chief WT. This has the larger wheel opening/flare. Install '77 Dodge D60's front and rear. The front should bolt right in with matching (very close) spring perches. The rear will require relocating the spring perches.

Strip out the AMC 360, trans, xcase. Replace with trusty GM TBI or Ramjet with a 4speed auto and atlas or beefed up D300.

The D60's with high steer, lockers, and sitting spring over, 35" tires (maybe 37's).

The things you have to do when the wife wants a dog....

I haven't done any measurements on this yet but this is likely a project I'll be taking on this year.

The rear will be wider than your current rear axle. This means your rear tires will most likely be under and outside the rear flare. In other words, at flex, your tires will hit the body and rub. Especially without significant lift.

I put 74 J10 axles under a 78 N/T Cherokee. They were really wide, but I was lifted w/ SOA and 4" springs, so it really didn't matter.

and a significant lift, if you plan on running 35s, probably at least 6 inches

Good point !
That's what says my 79 jeep data book
The standard J10 had normal wheels, and the standard cherokee WT had wide wheels
Actually the J10 could have wide wheels (15x8) as an option or with some packages, and the track width in this case is the same as for the Cherokee WT : 65.4''
