My 2015 2500HD. 4x4 with 8 ft. bed came with Michilen tires and has been smooth as glass since new.

I have Michelin ATX A/T2. Stock tires that came on truck.

Batak, I basic have the same truck only it’s a 2015. Mine is smooth as glass at all speeds.

What?? Your driveshaft turns when your in neutral? Better get that looked into.

I wonder if this symptom is unique to short bed trucks. My 2015 GMC 2500 4 x 4 with Duramax Diesel long bed truck with 25k miles is smooth as glass. No vibes, best truck I’ve ever owned and I’ve owned all three brands.

Agree! I've had a couple Fords starting with a 1978, had a 1992 Dodge Cumins, but my 2015 2500 HD duramax is the best truck I've owned so far! No Vibs on mine. Mine is a club cab with full length bed, wonder if these vibs are confined to short bed trucks. Don't see many long beds on the road around here.

Not me have had Fords and Dodge Cummins. Now have a 2015 4x4 Sierra. Best truck I've ever owned. Absolutely love it. No vibs here.

Great explaination. We use the same thing on turbine engines. Like you said, every part has it own RPM, frequency etc. So it's pretty easy to nail down a bad bearing etc. Someone ought to start a speadsheet on this vibration problem, What year models, what type tires, 2 wheel, 4 wheel, crew cab long bed or short bed, see if there is common bond. My truck is 2015 2500 4 x 4 long 8 ft. bed 4 door Sierra and I have absolutely NO vibration what so ever. Best truck I've ever owned and I've had Fords, Chevy's and Dodges.

Well I understand the frustration. I wonder how many of us don't have the vib. issue? My 2015 2500 Sierra with an 8 ft. bed and Duramax runs perfectly and smooth as glass. Coming from a 92 Dodge Cummins this is a perfect truck for me. Sent from my SM-G900V using Tapatalk

My beauty, 2015 2500 HD 4x4 Duramax Long Bed
