I would trust a junk yard before I trust a yahoo on Craigslist.

And what size are the tires?

I bought mine used from an off road acquaintance. Paid either $30 or $40, can't remember anymore.

My 29" tires (235/75R15) just barely rubbed (but still rubbed) when they were new. A few thousand miles (and a few sixteenths of tread) later they don't anymore.

My Pioneer is an 87.

You will have to cut the steel sleeves flush with the rubber bushing to make them fit. Takes a few minutes with an angle grinder and a cutting disc.

Pioneer is supposedly one step up from base model, but mine came with the 4.0, automatic transmission, 4wd, full gauges, bucket seats, fog lights, rear slider window, vent windows that open, 10 spoke aluminum (turbine) rims, hockey stick arm rests, map pockets, chrome bumpers, chrome grill and chrome adjustable breakaway mirrors. I'm pretty sure some of these options would have had to have been ordered separately. My other Comanche was bare: 4 cylinder, 4 speed stick, 2wd, steel wheels, radio delete, no cigarette lighter, no dash clock, single piece rear window, vent windows that don't open, bench seat, black bumpers, black grill. Both are 1987, serial numbers are only 11 apart. Still thinking the 10 in between would statistically have been Cherokees.

No fitment problems other than rubbing the lower control arms when you steer to sharp. WJ lower control arms will help, but might still not completely eliminate it. If you don't go off road I would stick with the ATs. MT tires wear a lot faster (like 20,000 miles to bald) and most of them suck in snow or rain.

I did it in my 94 a couple years ago, and on my 96 just last month.

Comanches are a lot wider in the back than they are in the front. Especially will larger tires the rear tires will contact the inside of the wheel well when you flex the suspension. To combat this you would run wheel spacers on the rear axle, but not on the front. On a stock Comanche I know some people (myself included) who do the same thing so the wheels will look the same front and back instead of sitting way back in under the rear fenders.

And a lot of the V8 swaps into Comanches and Cherokees have cooling problems.

In that case, get the Cherokee and use all the parts off it except the engine and rear driveshaft. After you're done, measure how long your rear driveshaft needs to be and have a drive train shop cut your 2wd one down to the correct length. If the axle gear ratio in the Cherokee is the same as in your Comanche you can keep your rear axle. If it is different you're going to have to take the Cherokee rear axle, cut off the spring perches and shock mounts, get some perches from Mopar Performance Part or whatever they are called nowadays and have them welded on in the correct location. Easiest would be to take the new axle, the perches and your old axle to a welding shop and tell them to "make this axle look like that one." Other option in case the gear ratio doesn't match is to not use the Cherokee's front axle and find one with the correct gear ratio in a junk yard instead. No cutting and welding involved this way, but most likely a lot more expensive.

I know someone that got thrown off a segway. Problem is when they lose traction, like on wet grass, or going uphill or taking off when there's gravel on the sidewalk they start to buck. The most money this guy could safely make is if he can patent the design and sell the patent to a large company for $50k or so. Edit to add: I stand corrected. It is going into production this year, first for sale in Asia, later in the USA.

The 4.0 can't backfire through the carb because it doesn't have one. The throttle body perhaps? The only times I've had these issues (2 different vehicles, neither was a Jeep) were a cracked distributor cap. Since yours has been replaced I would suspect the plug wires. Couldn't hurt to replace the plugs while you're at it. Use just regular good old fashioned copper core ones like the Champion truck ones. The 4.0 doesn't seem to like all the newfangled iridium, gold, platinum, or unobtanium ones.

You can't bolt a transfer case to a 2wd transmission. The case is different and the output shaft is different. The 2.8 V6 has the same bellhousing pattern as the 2.5 inline 4, so the transmission out of it will bolt to your engine. If it is automatic, I don't know if anything else is needed to make an 86 automatic transmission work correctly. Of course you could swap in the entire engine and engine bay harness as well for slightly more torque, basically the same HP and half the fuel economy of your 4 cylinder. If you want to keep a stick shift, you're going to have to find another stick shift with 4wd to get the transmission from.

Depends on the baskspacing of the wheels and what's been done to clearance the wheel wells.

As for the difference between 91 and 92, according to someones signature on this board (Pete?), the 92 will have more drool on it.

Is it possible they are dual layer PCBs?

Purple People Eater (originally 2wd 4 cylinder/AX4) is supposed to have 27" tires, but I run 29" (235/75R15). Speedo is off about 6 or 7% which is how I know. Door sticker is missing. Wilbur and Sparkles came from the factory with 28" (225/75R15), both are 4.0/automatic, Sparkles originally 2wd. Booger (4.0/AX15) was supposed to have 215/75R15. These three according to the door sticker. What I find amusing is in two of the four, the glove box lists tire inflation numbers for 195/75R15 (smaller than the smallest from the factory AFAIK), 205, 215 and 225. 235/75R15 is not listed (and can sometimes contact the lower control arms) but seems to be the most common size tire run on our Jeeps after the originals wear out. Actually, I also think it is the most common tire size manufactured.

He may still have some in stock. IIRC, the 3" lift ones are gone, but he should still have some of the other ones, including MT ones.

The VIN will tell what year Comanche it is, which is what the OP is asking for in the thread title.

There are three vacuum lines going to the axle, one to engage it, one to disengage it, and one to turn on the 4wd light when engaged. If the light comes on, the axle is working, so the problem must be in the transfer case (or missing a front driveshaft). As far as no power with 31" tires, it's not usually that bad with an automatic transmission, but that gives you 3.55 gears. I had 29" tires on the only vehicle I have had with a 4.0/5 speed and 3.07 gears, though and had no problem getting up to 65, 75 or even 90, or, on flat ground, maintaining any speed above 35mph. I really doubt 7% less torque because of the larger tires would make that much of a difference, so you may have engine problems as well.

Agree. I need a better TV.

Your TV is probably better than mine, but to me they looked a lot more like this first picture than the second one. Didn't record it, though, so I couldn't pause it. Boomerang shackles: Revolver shackles:
