Rear axle loud pop

[dbartromsut]

I was out wheeling this weekend and had my 08 h2 climbing up a pretty steep rocky hill. I had my truck in low with the axle locked and when I got on it it sounded and felt like my locker was disengaging. There was a loud pop, it was so loud that the first time it happened I thought I broke an axle shaft.

No idea what is going on. Any help would be awesome!

Lockers arent mean for high rpms/speed. You may have fubar'd something in there. Get on pavement, lock the dif and make a sharp turn and you will be able to tell if your locker is engaging or not. Nonetheless, can you say warantay!


FYI, you may not want to tell them you were getting on it, but perhaps you were going up a gravel hill at low speed and you wanted to maintain traction ;). However, in my past Hummer has warrantied off road damage including GMPP.

I tested it and my locker is defiantly working. But when I put it under a load like climbing a steep hill it still pops loud. I thought maybe there was some sort of safety feature that let the locker slip so you don't break an axle.

Anyways I'm going to run her by the dealership and have them take a look at it. Thanks for your help!

It sounds like something in your rear diff...busted tooth.
