The guy told me he swapped the rear differential for 3.73 and that I needed to swap the front because he didn’t know what gear it was and that the 4x4 should work once I swapped
I took out the current differential and it was 3.73 so no need to be replaced but 4x4 didn’t work when I got it and it went to 40 mph but just revs after 40 mph
I bought a 89 truck with a rear 2500 6 lug 14 bolt sf 3.73 gear recently installed but I want to know what I need to do or which gear do I need to install for the gears to be the same infront
