I have a 89 comanche 4x4, 4.5 lift, Dana 44, posi loc, 32" all terrains, and winch bumper. I moved to an area with about a mile long driveway that is off-roading pretty much the whole way and already caught my driveshaft on a rock and broke it which bent rear leaf springs and chipped rear differential gears. I was wondering what are the best upgrades that will make my comanche the most reliable and will help me get up driveway on bad weather days such as snow and mud. I got the driveshaft fixed, new rear leaf springs, the mechanic says the gears are fine for now, and also has the posi lok put in because the vacuum system was just not staying locked in. So what are some of the best things I can get to make sure I don't run into issues again or get stuck?
