If you run your truck in 4wd...center diff unlocked...hubs unlocked, your transfer case is gonna send 70% power to the rear (good) & 30% to the front (bad!). If center diff locked, transfer case will send 50% front & 50% rear. Still bad!

It will feel like your tranny is slipping as your only getting 70% or 50% power to move the rig depending on the situation.

I've also heard this can be bad for your transfer case.

None
