2011 EB Screw 3.73 locker 18k miles. Makes a noise I can only relate to ABS kicking in except I'm accelerating. Happens only when "stuck" or at least when forward momentum is stopped and restarted. I turned off TC and Advance Track with no change. I was trying to overcome some ice at the bottom of my driveway (stupid curbs.) I locked the diff and she scooted right up despite the noise. This isn't the first time I've noticed it.

Also, I get a vibration in 4WD at ~40MPH when accelerating moderately. This too can be felt in the pedal.

Thanks,

-Brian

The ABS noise is the AdvanceTrac system coping for wheelspin. No way to turn it all the way off except in 4WDLO.

The vibration could be a driveline imbalance. I'd take it in to the dealer.

Cool, thanks guys. I'm going to crawl under the truck and make sure there is no snow or anything causing the imbalance and go from there.
