Thanks for your help,
I don't plan to beat this thing like the Mammoth, but would like to be setup so I don't start the Jeep thing.
I just ordered 4.27:1 Yukon gears and Detroit True Trac carriers. I plan on running 33" MTR's so it has good road manners.
Harbor Freight you say
I think I am going use the stock axles for now, but use a better Ujoint. Is there a good chromoly joint that won't break the bank?
I have a spare set of stub axles on the way.
Oh, and I may have to retube the front axle due to road salt poisoning. What would be a good caster angle?
