I still run the Dana 30 in the front of my 84 cj7.My rear is a 44..My 30 diff is welded.It does like to eat Lock Outs tho...I always carry a spare set.Never broke an axle or ring and pinion..5 bolt 30 lock outs are a dime a dozen.Have a 44 for the front that will be put in this winter..Along with a SOA and new Eagle Valley Fab bumpers.
