Opinions on detroit in D 30
Daughter's 95 YJ has 9" in rear with detroit, she now wants a detroit in
the front, I read verying opinions on the YJs Dana 30 and putting in a detroit locker, I understand if I put one in my CJ and unlock the hubs, no locker problems, but what about the YJ with it's vacum, some one said the YJ always has one axle engaged or something like that, and I also read that something changed with the 95 YJs D 30, passenger side solid axle? So what's everyones opinion, I'd prefer to here from YJ owners with detroits in front, or just opinions on Dana 30 with detroit, I don't want to here about axle swaps, or Currie/Dynatrac options. Thanks. |

The driver's side axle on the YJ is always "engaged", but with the transfer
case in 2H there is no load on it. I don't know whether the axle can drive the pinion in this situation, but even if it does it won't cause problems. It will just cause the front drive shaft to turn. This isn't exactly what you want for highway commuting, but if your daughter's YJ is mainly for offroad (and why else would it have two lockers) then you should be fine. That's my opinion, but you should probably talk to someone who has done this, before trying it yourself.

I have the detroit EZLocker in my D30 (in a CJ5) and I leave the hubs locked
all of the time. I can't remember the last time the hubs were unlocked because anytime I unlock them, I turn around in less than 20 miles and lick them again anyway. I decided that unlocking the hubs was highly over rated. When your YJ is in 2WD, the front will never know that a locker is installed.

Thanks, mine's acually a CJ so I will be unlocking anyway so not worried
about it, but I was worried about daughter's YJ and no hubs to unlock.

It won't be a problem. My brother has a YJ with a locker in the front, and
he has no problems at all. I'm certain that you have used your CJ on at least one occasion with the front hubs locked and the tcase set to 2HI. I drive my CJ like this all of the time, I mean A-L-L of the time. The only "problem" is that it tends to be noisy at parking lot speeds when I pull into a parking spot. Depressing the clutch and rolling into the spot makes everything quiet ...

Ya I don't worry about unlocking hubs most times as mine is 99% for off
road it is just to the off road and back on weekends, I only unlock if I am going to be driving around town. A freind here has a lockright in the front of his YJ and has no problems but I just thought I would ask anyway. At $409.00 for a D 30 detroit we can't go wrong for what it will do, I remeber when I first got my rear detroit it was like the difference between a 2 wheel drive and a 4 wheel drive, maybe even more so. Anyway I wont worry about her, will order them both on Monday. "Jeff Strickland" > wrote in message ... > It won't be a problem.

For this reason, it is possible to change the carrier without disturbing the pinion settings. In my experience, once you get the carrier bearing preload and gear lash set, you are good to go. Of course, a prudent mechanic would check the gear contact pattern before driving off. You do need shims, and you might want new carrier bearings, unless you have the bearing puller to get the old ones off the old carrier, but the master rebuild kit is not necessary. Earle |

I'm not sure why you would want a Full Detroit in the front axle, the front
does not carry the same loads as the rear, and the Detroit EZ Locker or the PowerTrax Lockright should do the duty fine. The affect on the front axle is the same in terms of the questions you asked earlier, but the cost is less and the reliability is on par.

From everything I read online the 95 YJ is the change year and has a one
piece axle and 297 Ujoints, her ujoints are deffinately bigger then in my 81 CJ7. As for set up and install kit, all gears are new and there is a guy up the road that according to all in town is the gear install king, he charged her $50.00 to put the detroit in the rear, of coarse that was her taking the 3rd member over to him, but I think he does them for about $100.00 Canadian.. We get one 6" snowfall a year so that isn't a consideration, as for lockright she went through 3 of those in the rear end and finally went to detroit. I've talked to her about a cable dissconnect on the front to get rid of vacum.
