So I've got a rear 44 with a trac-loc 3.55 diff 30 spline, the spider gears are shot to hell and it's my daily driver. I'm on 33's so I know I need a better gear ratio. I've been doing some digging and found a couple rodeos that have a 44 rear end and 4.30 ratio 30 spline. If I disconnect the front drive train can I harvest the whole diff, ring and pinion for the rear and make it drivable again until I can upgrade the front end too? Is this something that is feasible with help from someone with a lot of experience?
