You need a 29 spline carrier, spiders, axles, and seals/bearings, basically have to swap all the internals.

not unless you break something. It's far easier to swap the entire axle.

Not really that much of an upgrade anyways from the 27 spline. 27 splines are fine up through 33s/35s.

Did renix stop in 90 or 91. Found a aw4 out of a 90. I was wondering cuz yhe renix ones will bolt to my transfer case. Also they are computer controlled right so i need the automatic renix computer? Does anyone know if they made the renix wiring harnesses universal (meaning i already have the plugins tucked away somewhere) or do i have to swap wiring

Stopped in 91. You're swapping a 5speed for an auto???? Good luck. You;re going to need a ton more stuff than just the tranny.

You need the bellhousing, flexplate, PCM, TCU, wiring harness, transfer case, both driveshafts, linkages, and console - basically the entire truck. The manuals are longer than the autos, and won't bolt up to each other.

I would advise against attempting this swap.

92 Cherokee, Automatic, 4.0L, 4x4 chokes and looses power.

While driving my Jeep, the engine starts to sputter (RPMs jump) then looses power, then starts backfiring. So far it hasn't stalled out completely yet. I have to pull off the road and wait for it to correct itself before i can continue driving, and i dont have any more problems until i the next day.

If i put in the Red Fuel Stabilizer, and put in 98 Octane it runs perfectly for that whole tank of gas.

Is there a reason i have to run it so rich? I know its not the gas because my other 94 Cherokee get the same gas with no trouble. Can someone help please?

Also, does anyone have a link to a vacuum diagram for my '92?

If you have like 10 minutes and a small piece of sandpaper I would like you to humor me. Directly behind where your gauge cluster is, but on the firewall (engine bay) there is a small bolt with threaded wire attached to it. Loosen it, sand until you see clean metal and retighten. Next go to your battery, coming of the negative terminal wire should be a wire that runs to the left and bolts directly to the body. Follow the same procedure as before. We will start easy and go from there. Please keep us informed as to your results. We love pictures also.
Cool, a total ground and wire freshening is on my spring/summer to do list anyway but I'll see if I can get this part done sooner. The battery terminals look pretty crappy and I see corrosion for sure. At work I have some NO-OX-ID conductive grease that we use for grounding (I work for a telco/ISP), so I'll slap a little of that on once I clean things up.

Also, I take it that the oil pressure fluctuating is normal to a rough idle?

Thanks!

This is just a suggestion, next to the air box attached to the frame. There is two little plugs. If one of those is lose or out of sack my jeep runs like crap and wants to die most times it does. Not saying this is your problem but its work a shot.

sounds like you may have sediment or water in your tank. Run it till the tank is almost empty, then add a bottle of drygas and about 3 gallons of gas, then run it till almost empty again.

he's talking about the fuel pump ballast resistor. You can completely bypass it (connect the wires together) without any issue (except perhaps more noise from the fuel pump)
