Snowy-Burn-Out Questions.....

:confused:

We had our first 3" of snow today, so I took out the silvy for some familiarization. Its a 2wd, stock, pretty much. I went and picked up two tubes of snow to put in back: 70 pounds each.

When I was coming down driveway I thought I would check braking, acceleration. I power braked it and BOTH wheels were spinning out. I tried without powerbraking to spin wheels and both rear wheels spin.

***Does this mean I have LS, or limited slip, or posi-track? I dont know what it is called. I have a non-ls truck and only one wheel will break loose.

Look at the RPO label in the glove box, if it says G80, it's got Eaton locking diff.

When very little traction is available, and both wheels have very close to the same traction, they will both spin even in an open diff.

If after you check out the RPO codes and it does not state that you have a posi unit, I hope that the same thing is not happening to yours that happened to mine a couple of years back. I knew for a fact that I did not have any type of limited slip or a posi unit because whenever I would step on it around a corner or hard enough in a straight line only one tire would spin. Then after a while I noticed that both would grab and there was even times that I deliberately held the brake and both would spin. That was all fine and dandy untill one day going around a corner there was all this extremely loud banging. Anyone that has ever had a rearend blow up on them knows how loud it can be. I found out from the guy that fixed it that the bearing on one of the spider gears in the rearend had seized so that spider gear stopped rotating and locked in place just like a posi unit does. To make a long story shorter, the bearing seized which in turn started wearing out the pin it was riding on causing the gear to cut into the shaft far enough untill the gears no longer meshed enough to hold.
