    Recently purchased a 2015 1500 sport. I tested all the drive options when I purchased the vehicle, but apparently didn't test it enough.

    This week I put it in 4 high due to some poor weather. I now notice that when I roll to a stop, and as soon as the speedometer hits zero there is a pretty pronounced clunk and jarring coming from under the vehicle. It feels as though something is slipping or disengaging (not sure if that is what's happening or not) . If I stop quickly the clunk does not occur, and it also does not occur in 2w or 4wd auto. I have not yet tried it in 4 low. There is no issue with acceleration, only with slow braking. Any ideas as to what the problem could be or recommendations would be appreciated. Thanks!

    I've heard of this over the years on many different vehicles that the driveshaft front splined yoke that mates the the trans output shaft binds up. The fix was to remove the shaft & apply some teflon impregnated grease to the splines. Of course the 1st thing you waht to do is check the rear trans mount and make sure its not bad.

    Yeah, never run it in 4x4 on roads unless you have auto.

    It's only in 4wd high that it happens. We've been getting a bit of snow, and was also out back behind the house when I had it in 4 high. Then basically forgot to switch out of it while doing a little bit of stop and go driving when I noticed it. It does not occur in 4 auto... I'll keep it there. Thanks for the input... I'm far from a mechanic, so any lead as to if it is actually a problem I should be concerned with is appreciated.

    There is no problem at all turning. It's only when coming to a stop... Thanks again!

    No problem. Certainly sounds like wind up to me. 4WD High should only be used on loose ground where the wheels can spin at different speeds.

    Cheers
    John.
