I don’t really know very much about gearing an all that so I need some help. I have an 4wd 89 Comanche with 33in tires, the previous owner says it has a Ford 8.8 rear end and new Yukon 3:73 gearing, it’s also an AX-15 manual. I’ve noticed it’s really slow uphills and not very good off-road uphill, so do I need to re gear? With the 8.8 rear end would 4.10 gears fit? Would I need to re hear front and back? Could I just run smaller tires? I don’t totally need 33s and would rather have less clearance but better uphill and it would be easier to do new tires than new gears?
