Your talkind bout the dana 30, right. There was no dana 35 front axle in any jeep. WEll Ive got a lockright in my d30. It had vacume disconect, but I swaped out for a one pice shaft. The only thing that happens in mine is when I make sharp turns I here clik, clik ,clik. Which is normal, just the locker un locking and doing its job. Ausiee works on the same idea as the lockright. If you have the disco axle you would be betert off. YOu will have no issuses.
