Need Advice on Axle Upgrades
I've come to the point where it's time to "re-gear" the Jeep. It's an '81 CJ8 with your basic stock Dana30 Front, AMC20 Rear w/3.31's, 33"x12.50 MT's. I use it mostly as my winter driver 75% on, 25% offroad with the "off" being snow, muddy backroads, hill climbing, pig hunting, nothing extreme. Gear ratio will be 4.11's.
My questions are:
1) What upgrades other than 1pc Axels should be done to the AMC20, and what type of Locker or Limited Slip would you recommend?
2) How strong is the D30? Can any of it's weaknesses be corrected during the gear change, or is it a waste to put money into it.
3) Is it worth putting ARB's in either of these Axles?
