I searched and didn't find any other problems/querks like I'm having.... so :flipoff2:

I recently switched from and ARB to a detroit locker in the rear of my '93 Wrangler (D35 Rear). I was told that the Detroit would click and knock when taking corners and act squirrelly under hard acceleration... Mine doesn't do either. If I dump the clutch, both tires will spin, and if I try to climb a hill in 2HI with a lot of throttle, they'll both spin.

But on the ranch that I frequent, we have a little whoop-de-do section that is perfect for lifting opposing tires, therefore halting any forward progress in open diff Jeeps. So today I wanted to make sure that the locker is truly working like it should be.

I approached the whoop-de-do (in 2HI), the diff's got crossed and my forward progress halted. I gave it a little gas thinking that might help engage the Detroit. What I heard was a strange screeching sound and only one tire turning (the one in the air). More throttle, more screeching and still no go.

I tried another hill that requires lockers (again in 2HI) and let the tires break loose to see if they were both spinning. They were. I shifted the Atlas II into 4LO, engaged the front ARB and it climbed the hill like it was childs play.

So what's going on here? Why wouldn't the Detroit engage when I lifted a rear tire? And what the hell was that screeching sound?

Do Detroits require a lot of throttle to engage? If so, that's bullshit. I don't like to crawl at full throttle. When I had the rear ARB engaged, it was truly engaged. This Detroit acts more like an open diff when a tire is in the air.

Do I HAVE to be in 4WD for the rear Detroit to be "LOCKED"?

Sorry for so many questions, but I'm perplexed about what's going on with the rear Detroit.

Thanks,
Ray

From the manual that came with my Detroit to test if it is working properly:
Jack up the end of the vehicle with the Detroit, both wheels up.
Vehicle in gear or park so driveshaft won't rotate.
Forward engagement test
2 people, rotate both wheels rearward till both engage.
Hold left wheel, rotate right wheel slowly forward, should hear faint click as right side disengages.
Rotate right wheel slowly forward, rotate left wheel forward to lock both wheels.
Rotate both rearward to lock both wheels.
With right wheel held, rotate left wheel slowly forward, should hear faint click as left side disengages.
Left wheel slowly rotating forward, right wheel rotated slowly forward till both locked.
Repeat above steps except test for reverse engagement.

Do Detroits require a lot of throttle to engage? If so, that's bullshit. I don't like to crawl at full throttle.
The Detroit is always engaged unless it disengages, like going around a corner off throttle.

landuseorc,
Thanks SO MUCH for taking the time to transcribe all that for me. I'll give it a try tomorrow to see whats going on.

Cheers! :beer:

Ok, I tried the tests as indicated above and as described on the Tractech website (http://www.tractech.com/TechTips.htm), but I never hear the clicking or indexing as described.

I did more field testing and found that if I drive the driver's side tire up an incline, it will go up with no questions asked. However, if I drive the passenger side up an incline, then forward motion is halted and the screeching starts until more throttle is used to launch the Jeep up the hill.

So now what??? :confused: I plan on talking to the guy that installed the locker tomorrow and see what they are going to do to rectify the problem. I'll post what the solution is once I know.

Sounds like a defective or broken locker to me.

I called the guy that installed it this morning. He told me to bring it in and he'd take care of it. I'll let you know the outcome.

Yeah. You can test it all day long, but if the thing doesn't lock up and cause the Jeep to go forward while one tire is off the ground, it's either broken or installed improperly.

The combination of an Atlas, throttle, and a locked 35 may be your problem. The 35 can't handle that. I wouldn't think the detroit would be the part that would break though?

I say jack up the side that wasn't spinning when it was in the air and see if it turns independantly, if so, broken axle. If the Detroit was installed wrong, how would any of it work??? Either that, or your "Detroit Locker" isn't a Detrot Locker at all.

But if that were the case his tire would have passed him on the way home assuming he has a C clip D35 like a '93 should.

I never did see, is this a full case detroit(softlocker or what ever there called) or a lunch box locker?

If its a lunch box locker then I bet he installed it wrong, didnt put the shim plates in or put the springs in wrong.

If its a full locker then it sounds like a defective unit.

Its the True track Vs the EZ locker.

True track ¡Ö $400
EZ locker ¡Ö $200

install ¡Ö $175

Which is it?

If I upgrade to the True track from my EZ how much more performance will I get?



:jeep:

That would be a down grade as far as traction goes because you would be running a limited slip instead of a locker

SWEET

I was told that it's a full detroit locker. I'm guessing that it was installed wrong. I'm taking it back to "Just Jeeps" on Tuesday to have them take another look at it. They are going to fix it for free since it's their goof...

okay, so it should be a real Detroit if it just replaced an ARB.

If it was up to me, when you get it back from the shop I'd open it up and make sure that you've got a Detroit in there and not a stock carrier with an EZlocker.

I agree, I would pull the diff cover and see whats in there. Not only that I would pull the diff cover and see if theres any shavings in the gear oil..

Anyone want to bet there is?

why did u take the arb out?

no shit, if you stripped a gear in the ARB just REPLACE IT!!! and disengage it when you don't need it:shaking: You blew up your ARB driving around on the street with it locked:shaking: I also wonder if you ever engaged it while moving:rolleyes:

Hell, I still can't figure out why you're dumping more money into a D35! The price of the two lockers would have been a good down payment on a 44.
Ok the ARB came with the Jeep. (I'm guessing you paid for it anyway in the purchace price)
Detroits are notorious for self-destructing in a 35. So what's next?
Wishing you luck, I'm thinking you'll need it.
