Truck is a 2006 2500HD with the LBZ Duramax.
I bought the truck at 178k, now at 193k. I did notice this when I test drove the truck, but didn't really think anything of it. When I get to a stop, I feel a jerk or clunk. Then when I get on the gas from a stop, I feel a clunk again. It's almost as if there might be slack in the driveshaft somewhere. Shifting into gear is fine, normal driving is fine. It's just on starts/stops. Transmission is fine, shifts perfect, etc.. Wondering if anyone else has had the issue before? I've been driving it since 178k with it doing this but for whatever reason haven't thought anything about it. Want to get it fixed. Ideas?

Motor mount, maybe? I've never had a Duramax, but I've had broken motor mounts on a few vehicles with similar symptoms, more on the taking off than the stopping. Good luck with it.

Check your suspension, sounds like ball joints, worn out bushings, differential, or u joints.

Lot of trucks have axle wrap that causes similar symptoms.

Might check to see if its a 2 piece driveshaft. Sometimes they make a bump feeling when stopping or taking off from a stop! Grease the joint if it is a 2 piece!

Grease the slip joint or joints on the drive shaft. You Tube has plenty of how to videos.

If the u joints are making that sound REPLACE them. They are too worn out and No amount of grease will fix them. They are cheap and easy to replace.

I'll get under there and grease everything up today to see if that makes a difference.
Something I forgot to add though.. If I pop it into neutral rolling to a stop, it doesn't do it. Just stops normally, put it into drive fine, hit the gas, bump. I also noticed that it only is noticable at operating temp. When the truck is still cold, it's very very minimal or not even noticable

You will have to remove the drive shaft and grease the yoke or yokes on the inside. Don't put too much grease in them, just a light thin layer of grease.

I looked up what you mention and they describe what mine is doing. Only thing is, I read that greaseing them will only last you 20-30k miles and it will come back.. I guess the only way to fix this for good is to just a new slip yoke? I don't want to pull the driveshaft every 20k miles or less

That's a crummy solution, unless they're offering it as a free replacement for owners, which I'm sure they're not...

I know it's not hurting anything, it's just annoying.
