I am plannig to change my axels and thought i would ask here what would be the best choice . im leaning towords the 2.5 rockwells because i think i can get a set maybe free and in my area the cucv's are alittle hard to come by and the rocks are alot stronger . but im not to happy with the 672 . 1 gears and the custom 20 inch rims and paying more for 20 inch tires . im going to by new 42 inch tires reguardless of the axel type . I like that the cucv's has a detroit locker and the chevy 8 lug rims but with the 42 inch tires im not happy with the 4:56 gears . Also what is the possiblity of breaking the stock drive shaft and u joints with the rockwell's ? Also what issues will i have installing power stering ?
