vibrations

dick laberge · July 2, 2004

I have had this vibration since the truck was six months old. It has beeb to the dwaler four times for this problem. it's a crew cab. They replaced the center bearing on the driveshaft twice,shimmed the rear end to change the angle, checked u joints, and I don,t know what else. They called the gmc engineer and he said it was a normal thing for that truck, He told the dealer that they have around forty thousand out there that do the same thing. If I am pulling my fith wheel it goes away. he said that the truck needs to be worked. I told him that I have driven tandem dump truck and they didn,t vibrate when empty. Looks like gm is snowing alot of people My truck is a 2002 2500hd crew cab duromax,auto. I added a banks system,brush gaurd ,running boards,hard tonough cover, color pewter

Have you had the driveshaft professionally balanced? If not, I would try this next as it can make a big difference and they are not balanced that well from factory.

He is correct. Not that it matters but, Dodges are currently in a recall of driveshafts on the new 3500s because of a driveline vibration due to poorly balanced drive shafts. They are getting new ones.

He's a bold face liar! These trucks are not designed with a vibration. That's just the cheap and easy way to "solve" the problem; if they can't figure it out then pretend it doesn't exist (kinda like CSK).

I assume you have the two piece drive shaft? If so, there's a TSB out to have that replaced with a big, one piece unit. It's designed to solve a problem with -- are you ready for this? -- vibrations!

Just get the whole assembly balanced. Two piece drive shafts properly balanced run very smoothly, I would not convert it over. I would do at your expensive and send a copy of the results and the bill to the dealer and area rep.

Thanks for the info about the one peice driveshaft. Would you believe it I got a survey from GM today I did use the back page to tell them what I thought. Ilove the engine though, get 15.5 mph hauling my 5th wheel and 22 withoiut it

My 2000 2500 4x4 x-cab sht bed has vibration that starts @ 60mph & gets worse as speed increases. Dealer has balanced tires, balanced both drive shafts, turned rotors, ujoints, replaced torque convertor & control valve, replaced front cv joints. Truck has been in shop over 43 days and counting! Now they are looking into rear diff. ? Needless to say, have lost all hope dealer knows what they are doing.
