    I don't plow much with this truck but I did sand with it yesterday. 2009 hd gmc reg cab. 25k for miles. But when in 4 wheel things sounds terrible. Rough when you turn, sounds kinda like grinding going on. When out of 4 wheel it sounds fine, rides good, but if you turn sharp something doesn't sounds quite right. Ay ideas? Nothing leaking under neath that I see.

    Don't drive in 4x4 on dry pavement. Your truck is fine.

    Or even wet pavement or semi-icy pavement. I agree that your truck is likely just fine.

    Could be a cv shaft going bad from driving on bare pavement in 4x4.

    Ok, now that the pavement issue has been thoroughly covered...did anyone notice that jvm81 didn't mention surface at all? Just in case jvm81 already knows about that and is describing a change in the way his truck operates, let's talk about other possibilities:

    A failed hub bearing, which is a very common failure, can act exactly like that.

    After all, he did say that something sounds not quite right when turning sharp in 2WD too.

    Jack the front end up and see if you have play in your front wheels, grab the top of the tire and pull it in and out and if it moves then it is cv most likely.

    That sounds like the standard wheel bearing test, although it's not conclusive...these hub bearings can make all kinds of noise and pass every test. :(

    I think after reading his post 3 times it's crabbing--either from him driving on dry pavement or possibly his front axle is engaged without him realizing it.

    Never in 4x4 much. When I use this truck sanding no need to be in 4 wheel I don't think. Plowing we'll run in 4wheel but this truck sounds rough. I have 5 other gmc trucks and this one just doesn't seem right. I realize no dry pavement and turning in 4 wheel but even in 2 wheel there is something that is not quite right. Maybe this weekend we jack it up and see what we find. Thanks for the input.
