Default detroit ez locker trouble.

dana 44.

The locker worked fine for a long time, many many miles. Two weeks ago, I broke an axle shaft and immediately disengaged the front axle on the t-case and at the lockouts, put it on a trailer and parked it.

Put in new alloy shafts, and new lockouts in, and went to play. Under acceleration the locker would snap and release one of the front tires.

If I drive in front wheel drive only, so the front axle is carrying the complete load, it pops horrible. If I'm in 4 wheel drive, it pops every once in a while and jerks very hard to the left or the right.

I ran a string on both front tires, and they are within a 1/4" in diameter of each other.

Popped open the diff cover, and the teeth look fine the pins and springs are still there, everything looks just as good as when killer b put it together.

Before I remove the locker and toss in some spiders and weld them together, is there anything I should look at? I've never messed around with lunch box lockers

It doesn't take much to get an EZ Locker to die a horrible, noisy death.

Ash can it, or shimm the heck out of the drivers, or just weld it together.

Yep. I never had issues with the 2.5, but the new 5.7 has a couple more hp.

Lincoln locker, here I come!

ITs not uncommon at all that they break when you lose a shaft or lockout. Even a detroit can bust.

I'd pull out the couplers and have a better look.

Do you have Hydro steering on that?

Some guys around here were bustin lockouts which took out the Detroilet everytime, 3 different rigs I think. Drive flanges seemed to cure this problem.

EZ Locker= bad design and quality

Ok, ripped it apart hoping to find something broken.

There is slop in the 4 pins, but I'm not sure if that is like that new. Found 4 or 5 teeth on both sides slightly rounded off, but I'm not sure if thats enough to mess it up.

two of the four holes where the pins go are oval, is that normal, or did the pins wear into the locker?

The 2nd picture doesn't show the wear. Its 5 teeth in a row that have a slight roundness to them.

I don't think this is enough to mess it up, hoepfully I am wrong. The other two variables are the new shafts and the new lockouts, but I don't think they could be wrong. I put in warn premiums, which come all assembled.

It doesn't take much for an EZ to stop working, and yours is hashed.

yeah, thought of that. Lockouts has no effect on it, though, unless you ar eghetto and unhook one in every turn...

You'll want a ram anyway for the 39s. My ram-assist setup is going on in a couple weeks. Under $200 for the whole shebang.

The slightly rounded teeth is enough to make that happen. My lockright was doing the same thing, slipping and clunking under acceleration. When I took it out, it was a few teeth that were worn. They could hold the load under lighter torque, but any power would make the teeth slip.

I'll just run with one locked, I should be fine for turning.

I'm going to the mounds tomorrow to give the whole rig its 2nd beating. Hopefully I break less then I did last time.

I've looked into ram assist, but I never came across the parts for under 200 bucks!

Did you happen to break a ujoint or axle shaft right before it stopped working?

That second picture of your looks just like my brothers does. He broke a shaft in a 8.25 then when he put it back together it made a "this does not compute" sound. I told him there was no way that the the roundness of the teeth would make that much difference... I guess I was wrong

Yes. It broke a d-shaft u joint at the rear pinion. It broke on pavement under acceleration. The lock right was never the same.

I can't tell from the pic you posted of your teeth. Did you check the clearances with it installed?

I've seen so many EZ lockers that looked OK, still snap like that though.

We struggled with a D30. First put a ez locker in and then a locrite. Couldn't get either one to work.

Discovered that the axle housing was bent a little and wondered if that would make a difference. Also, there is a gap measurement, I think around .170" between the face of the gears. That was a little over the high limit. Ended up selling the POS.

I ran a jeep for years welded front and rear with 38's and stock steering. It'l be fine until you get in tight manuevering. Unlocking one hub is a PITA but you will get by at the dunes.

You don't need no stinkin 60. Just put a detroit in it and hydro assist.
