How much rear tire skip is normal w/1008?

[camdensc]

When making slow speed tight turns, my 1008 has more inside tire "Skip" or "Spin" than I have been used to on my other vehicles. I believe that this is due to the type of rear differential. Is this something normal for our trucks?

Thanks

The Detroit Locker in the back is responsible. Normal operation for this type of differential.

Will any of the oil additives help, or is it just the design of the Detroit?

That's just the nature of the Detroit. You don't really even notice it after a while. Application of the throttle will increase the lock-up as you go through a turn, so you might try letting up on the throttle if possible. The Detroit doesn't require any special additives since it has no clutches. I'm running a synthetic lube in mine, but I don't think I have really noticed any real difference from the dino oil.

I appreciate it, thank you.

Camden, welcome to the world of real trucks!!

The detroit locker in your rear axle basically allows either tire to ratchet AHEAD of driven speed, but not fall behind. This in effect means you're always driving off the INSIDE tire in a turn, while the outside tire is allowed to ratchet free (faster than the inside tire). So if you throttle it up some, the inside actually just slips some, and you drive off both them. No additive softens it, as it's not clutches, it's dog teeth that cam apart to differentiate. This is just how it is...

Note that this means the power on, you'll ALWAYS spin both tires at exactly the same speed, unless something's broke, which isn't likely. Good for donuts in the snow, good for wheeling, but kinda hard on tires if you're generous on the skinny pedal... You'll occasionally hear it bang too. And I notice it push the truck around a little too, but that's probably allowed more by some plany in the steering...

The right rear tread is almost bald compared to the other tires, probably from the tighter right hand turns at intersections I guess. Do you rotate your tires any more often because of this?
