4wd Noise

[kenstruck]

Hi there,

 

I'm new to the forums but I've been reading them for a few days doing a bit of research. I've got a 2003 Silverado 1500 with the electronic switch on the instrument panel to engage the 4 wheel drive. I'm noticing what I would call a grinding noise coming from the drivers side front when I activate either the auto 4WD or 4 hi. Its very noticeable when I make the switch on the move and will persist until I switch back to 2DW. I could not hear it when I engaged the 4WD and drove in reverse up my driveway...its a pretty long driveway so I think I would have heard it but I can't be sure.

 

From other posts on the board concerning similar problems, I'm leaning in the direction of the wheel bearing on that side but I wanted to pick a few brains here to be sure.

 

 

Thanks,

 

Ken
