someotherguy Posted February 5, 2017 Report Share Posted February 5, 2017 I'm no expert but from what I've read right here on the forum, it's your front diff. When it's blown, your truck will roll in park. Richard Quote Link to comment Share on other sites More sharing options...

03lsxss Posted February 7, 2017 Author Report Share Posted February 7, 2017 Ok today i took the truck to the dealership one of their mechanics came out looked at the roll when it was in park. And then got in it put it in reverse backed up and then pulled forward looked at me and told me bad viscous coupler. Not sure what to think anyone have this happen to them.

EXGM Posted February 9, 2017 Report Share Posted February 9, 2017 Do yourself a favor crawl underneath and pull the fill plugs. I guarantee one will have a ton of metal in it (or no fluid). You will then know which one is your problem..... another option is put your computer REALLY close to the truck and then one of us will be able to tell what the problem is....
