Have an '07 Crew 2WD with locking rear end. After letting sealer on driveway dry I was backing diagonally over a ditch that runs between mine and the neighbors driveway and heard and felt a large clunck; it was as if I had hit something. This happened asone of the rear wheels began to loose traction.I got out and looked both times even though I knew there was nothing for me to hit. Could this benormal behavior when the rear axle locks. If so I wouldn't want it to to be used very often. Felt as if I backed into a solid brick wall.

 

So, anybody had their locking rear end to engage. I was hoping someone could tell me how their truck behaved. Was there a large clunk like you just hit something solid?

 

i do not have the locking rear end. or any type of locking rear. sadly its open but i have seen videos of the silverado on a test coarse where one side was concrete the other was rolling pins in the ground and the silverado was at a 30 degree incline. when the truck went up one tire was spinning and then you hear a loud bump and the truck instantly gets traction. the other tire broke loose from the instant traction then just went up the hill no problem what so ever

 

check out the vid, pretty neat
