Normal for my rear axle to be locked?

[dieselsmokem35a2]

I have an M1008 and when I make a left or right hand turn on pavement the rear tires chirp. I know it's not from the massive amounts of power! LOL Is the rear axle supposed to always be locked?

It is not supposed to be always locked, but they can lock up easily. With no load, on hard turns, some "chirping" & hopping is normal. If you are easy on the acceleration, this affect is lessened.

it has a locker its always locked on a M1008 its fine.

I always related it to over powering, its gets real interesting without the bed on.

To minimize this try to make your turns in a coasting fashion. Powering through a turn with the Detroit locker in the rear will cause it to lock, coasting (when possible) through a turn will help it stay free.

Anything under acceleration on a Detroit Locker in a tight turn should cause it to lock. They are set up so one wheel can coast faster than the driven wheel, but the driven wheel cannot spin faster than the coasting wheel, if that makes sense. They normally are quite harsh when they lock up, especially obvious in a 4.56 gear. Like some others mentioned, you should be able to coast around a turn with no problem or drive around the corner with neutral power. Under load, they should lock up. Another thing you may find is a bang when backing in a curve, then going to drive. If you catch the locker in the middle of locking up and reverse directions, it will ring your driveshaft. Harsh, but among the strongest locking systems out there.

Whats likely happening is the outside tire is coasting and the inside tire is doing all the driving. This makes the inside tire very easy to slip ( chirp) and cause a little rubber to be left on the road. I have 3 Chev trucks with 14 bolt/detroit lockers and they all do this. Right side tires wear faster on the detriot locker trucks because the right hand turns are at a much tighter radius than left handers.

Thanks to all you guys for your input! I am relieved to hear that its normal. I will try the coasting methode from now on. Thanks again for taking the time to educate me, much appreciated!
