Have a duramax with 4 wheel drive. I noticed this happening just this year more so than ever before shifting out of 4 wheel drive going from snow to more of a dry road i really get a vibration. I do like to drive it in 4 wheel drive in icy or unsafe conditions.

Obviously I know not to drive it in 4 wheel on dry roads wondering if U joints on my front drive shaft may be causing this. Just had the fluids changed and the problem persists. No problems shifting in or out

Thankis

Hi there,

I would certainly be checking the front uni's and the sliding yoke, also all the front end suspension support mounts are tight, start here.
