What kind of gearing would have come stock in a 1986 MJ Comanche 4wd, with a 2.5 motor, Automatic transmission, Dana 30 front & Dana 35 rear?

i believe that was one of the few that came with the 4.56 ratio

If you have the truck, you should be able to check the Tag on the Pumpkin if it hasn't been messed with or rusted off...

Could be 3.55 or 4.10. As far as I can tell, 4.56 wasn't an option in 86.

 

Jack up one of the rear tires and put the truck in neutral. Spin the free tire around twice and carefully count the revolutions of the driveshaft. If it goes around three and a half times, it's 3.55. If it goes around just a bit more the four times, it's 4.10. If it's something else, let us know. :D

With an automatic, it could well have been 3.73s

Oh good, so it's either 3.55, 3.73, 4.10, or 4.56 :rotfl2:
