I have a 2007 2500HD single cab, long bed, 2wd, 6.0 V8 with about 28k miles on it.

I have experienced a vibration since the truck was purchased new a little over a year ago. Selling dealer has balanced and rebalanced the tires more times than I can count. The owner of the dealer finally told the techs to stop working on the truck and advised me thats they way these trucks ride because of the frame. He advised me that it would not vibrate with a load either in the bed or behind the truck.

With three horses in a steel trailer behind the truck, it vibrated just as bad, no improvement.

Went to another dealer who had the tires/wheels road forced balance. This determined that two tires and two wheels were out of "spec". Put 4 new steel wheels and 4 new Bridgestone tires (a different brand from what was on originally) 80% improvement. Still had a little shimmy, but compared to what I had been riding with, it was perfect...of course I said I was happy with the improvement, which I guess I should have not.

2 weeks ago I had a routine service including a tire rotation. The vibration is back with a vengeance. It carries over into my horse trailer and the seat belt locks up the shake is so bad. Starts at about 40mph and gets darn right unbearable at 65mph thru 75mph...starts to dissipate around 80mph. Of course my typical cruising speed with the trailer is 65 to 70.

I would like to know if anyone else has had this experience with this truck and/or has any ideas. I have an appointment to go back to the dealer tomorrow, and am being told again its a tire balance issue.

I haul with this truck at least once a week and love the way it pulls, but this vibration is getting REALLY old after a year!

Thanks.

 

i have the same setup you have with 13,900 miles mine is starting run very rough but for me its not tires its gotta be motor or trans cause it does it at idle. does pull pretty good though.

 

Motor runs fine. Drive train was checked by putting it in neutral while cruising down a hill around 60mph, still vibrates.

This doesn't rule out any rear end problems, but I have not had a tech look past the wheels and tires at all....and that would seemingly be the problem.

With as much as I have spent on tire balancing I could have probably purchased a nice new set of machined wheels.

 

you don't by any chance get water in your tires do ya?? you ever air up your tires at home and have maybe water in your air tank?? the water will lay at the bottom of your tire until going fast enough that the water will start to rotate with the tire, a tire balancing machine will not spill the tire fast enough to get the water to rotorate, thus the machine would say it tire is balanced, and it is untill the water starts to rotate with the tire. the only way to find out would be to take the tire of the rim, from what you write it can't be very much if this is your problem. if it were a lot of water you would not be able to keep the truck on the road it would shake so bad.

 

I have not messed with the tires either at home or with any sort of air tank anywhere. since this has been going on from almost day one I have been very careful about "doctoring" it myself. I want GM to figure it out.

Went in today and the tech drove it...yep, you have a bad vibration. Tires balanced fine...3 of them deliberated for about 45 minutes. At one point I heard the tech say..."It has a bad vibration, I can feel it, its very bad, but I am not convinced its the tires. It could be the RF tire, it could be, but, I am not sure".

So, they think the RF tire is "bad", so they have ordered a new tire. I was told that the problem with that is that Bridgestone does not offer this model number anymore. So, they are going to order what they think is comparable, BUT, if this fixes the vibration is may make the truck pull to one side because of the difference in tread pattern. Theres only one way to find out I guess.

 

you could try getting a different set of wheels and tires whether stock or aftermarket and put those on and drive it and see what happens. im not saying go buy a set just to do this. im sure the dealership has a set laying around they could throw on it for a test drive.

 

Thats what I tried to talk them into doing today to just see, before we ordered more tires. I was told they did not have any 8 lug wheels with tires laying around, and there were no 3/4 ton pick ups on the lot.

The set of 4 wheels and tires that are on it now are a whole 6 months old, they were to replace to set put on the truck at manufacturing, that were apparently out of "spec". So, it has had 2 sets of wheels and tires in a year and a half. Still vibrating...

 

I had the same problem with my brand new 2009 2500HD Silverado. I purchased the truck with 100 miles on it and had the tires replaced with 265 75 16.. I've also had the tires reblanced several times. After dealing with the tire dealer and calling Goodyear I was informed and backed it up by checking there website that they were correct.. The tires I purchsed were the right size for the rim but needed to be mounted on a rim 7 to 8 inces. The OEM rims are only 6.5" and are causing the tires to "buckle" while driving and actually moving the tire.. Ordered new rims (8") problem solved!

 

If it was better before they rotated and worse after it almost has to be the tires. Have them rotate them back if it get better again it is the tires for sure. What is the road force number? At my work anything with a road force number of 15 or higher we match mount. We have found anything much more than 15 will hop (vibrate). I very rarely find bad wheels but bad tires quite often. Most of the time with Bridgestones we see high road force numbers but can match mount more than half down. Goodyear is the worst. Next time you buy tires I recommend tirerack.com and have them sent to a recommended installer on their web site. They will replace any tire that has a roadforce over 15 and can not be match mounted.

 

maybe your driveshaft is out of balance. In my 89 I pulled a driveshaft out of the junkyard and it caused a bad vibration, got it balanced and was good to go.
