detroit locker dana 30

I want to put a detroit locker in my 87 yj. I have heard that a hub conversion kit is required to keep the front axle from turning all the time. I only use my jeep on the street for short trips. I put an soa kit in & also swapped in an 8.8 rear. I have 4.10 gears. I also have a cable to disconnect the front axle instead of the vacuum unit. My biggest concern is damaging the locker. Can somebody steer me down the right trail?

So does the Jeep go off road then? Either way, yes you can run one up front, I ran a lock-right for a few years in my TJ dana 30 which is for the most part the same. Not sure but I think the detroit will let you know its up there a bit more than the smaller drop in style lockers do. Most of the time you should not have any effect, maybe some clicking sounds, and in tight turns it might skip, and we will leave snow covered roads out for now since you only take short trips.. thus, save a few bucks, get a drop in locker and be happy.

I am going to agree with 4Jeepn (never thought I would say that, kinda scary! ) go with some kind of "luchbox" locker in the front and unless you are in 4-wheel drive, you won't notice it most of the time. Don't waste your money on a Detroit with the stock Dana 30 axle. But the handling should be fine.

If you have to ask what it is or what it does, you don't need it, and you will need help to install it!

I have to agree too with the lunch box locker idea. I don't think the D30 is worth spending that much money on. You said that you have a SOA, which means that you can fit bigger tires than the D30 can handle. Once you lock it up you could be pushing the D30 pretty hard and will probably look for a D44 or other swap in the future to keep it together and reliable. Myself, I would like to wait until I can get a pair of 44's before I invest any cash in lockers, but I may throw a relatively inexpensive lunchbox locker in to get me through.

go with a lunchbox style locker, cheaper and easier on parts...I wouldn't invest in a detroit unless it's going in a bigger axle...

If you are going to run stock axels you should either use a Lockrite or Aussie. they are stronger than the stock axels. if set up properly they will do a awe sum Job. before you teardown you may want to think about a ring and pinion change at the same time. I want 4.88 to use with 35 " tires.. that would still be a good combo on the street.
