Just went to google, you are so right on, EVERYONE has 3:54...[emoji1][emoji1] Sent from my iPad using Tapatalk

The donor is 90 Cherokee 5speed, will check when I pull transfer case and let you know what the spline count is... Sent from my iPad using Tapatalk

The rear diff is Dana 44, finding 3:54 for the 44 might be a challenge but probably not impossible, something to dwell on, was just happy to find the 3:07 and hadn't thought about changing ratio. Sent from my iPad using Tapatalk

So the transfer case from the 90 should be compatible with the AX15 in my 91?hoping to pull everything from the one cherokee.. Sent from my iPad using Tapatalk

Hi guys, have recently picked up my 3rd mj, 2 wd, 1991 long box, with 5 speed(AX-15) newer 4.0, serial # search says it has 3:07 rear diff. Would like to convert to 4wd.Local jy has a front 4x4 axle from 1990 Cherokee serial # search says it has 3:07, I am gonna assume it would be vac operated, which I again assume is an easy fix? Question is should I look into using transfer case from the 90 Cherokee or look for a later year, would the 90 Cherokee have a Peugeot tranny or Ax15? Sent from my iPad using Tapatalk

Those drop brackets look like mine. I bought a 4" Rough Country lift about 4 years ago. I have mine all the way forward. No interference. Sent from my SAMSUNG-SM-G935A using Tapatalk Sent from my iPad using Tapatalk

For my 89, the fuel gauge needs to be from 87-90 ? Might explain why it read full al the time, key off and key on....

Just picked up a 97 xj booster and master from Gary's Maple Ridge $40. Sent from my iPad using Tapatalk

Any luck with the research on this Dirty C..... with my limited experience with square body GMs my thinking is it will fit on firewall, the exciting part might be in fitting in the power steering pump,

Replaced fuel gauge, looked at and cleaned up the rear light ground, gauge still reads at full, with key on and key off so now it is time to look at the sending unit itself didnt really want to mess with the sending unit as they are hard to find but will pull it out and check it, did find a link to the rebuld web site.... also the mechanical speedo unit slides right in to replace the electronic unit..sweet..

I am starting to enjoy this forum, shouda got a Comanche long time ago :) :) :)

Ok lets assume bad ground, would that be at the sender or at the gauge..

Thanks mike, there are vendors on Ebay, Amazon and Autozone claiming they have sending units for the MJ but also claim the same unit fits the XJ, guess to replace sending unit it is by having it rebuilt or finding a used one.

Getting back to the original post.... is there an aftermarket fuel sending unit for the 89 Lb Comanche or are suppliers just assuming that the XJ units will fit the MJ and selling them as such....

Hey guys, thanks for the input, am in process of pulling gauge cluster, hope to replace the fuel gauge or whole cluster with one from wreckers, another question tho, the po replaced the original trans and transfer case, the transfer case is from a 91 and has the electronic speedo plug while the cable from the speedometer is the mechanical gear driven, been told just need to replace the electronic plug on the transfer case with the older mechanical plug, seems to be to easy a fix to me, anyone with experience with this....

Thanks for tip, will look at replacing fuel gauge first, that will probably be the easiest place to start...

Thanks for quick reply, the gauge reads full constantly, even with key off it remains pegged at full. From research I have done on here and other places what I am finding is that the fuel sending unit is not available and was surprised when i searched on goggle and found it at Autozone and on Amazon but are they just selling the XJ unit thinking it will fit the MJ....

Just picked up a 89 4.0 L, 5 speed LB and the fuel gauge is pegged at full, tracked down replacement sending units at Autozone and on Amazon, trouble is the Delphi part number are different, Autozone says the part I need is HP10148 while different retailers on amazon say the part is HP101147. Any help with this would be appreciated. Thanks
