1993 Jeep Wrangler Q&A
1993 Jeep Wrangler Question: differential
I have a 93 Jeep wrangler that has a Dana 44, 4:10 ratio. While driving one day the spider gears in the differential broke. I opened the dif and cleaned out all the metal I tried to rotate the case but it only rotates half way and stops. I double checked for metal shavings or chunks but could not find any; the pinion and the ring are locking. I think that the adjustment is lost; nobody’s ever touched the rear end outside of general maintenance. I can’t find what is holding it but if I loosen the bolts on the left it spins freely. This is my primary vehicle; I need to fix this myself because I don’t have the money to pay someone else, please help. I know that the Jeep Cherokee 87-91 came with a Dana 44 and other makes like the Isuzu Rodeo. My question is if they have the same ratio 4:10 and the shaft is the same diameter can I take the case with the pinion from a donor vehicle and transplant it to my jeep? I don’t have a welding machine to do the work required to swap out a rear end. I have been at the junk yards and it has been difficult to find wranglers. Please let me know if the transplant is possible and if there are any other vehicles with the same diff that I can use as donors. - ninicharo

So...I screwed up, and put a quart of 80W-90 oil in my front differential, instead of the rear. And...when I realized my mistake...I combined quarts of 80W-90 with 85W...
