Called gm customer service again yesterday and my case is still open at least. I really wanted to get them to say that they are hearing about this problem form other people than just me. I have talked to 3 specialist and they claim that mine is the first time they have heard about the vibration. They had talked to the sm at the dealer I am using and he has a plan to try and fix it on my 2nd trip after the road force balance. Talked to him yesterday and he wants to keep it for a full day to mount a different set of tires and wheels to try that out.

I had the road force balance done as well. They said that they were as in balance as possible, but rebalanced anyway and when I got back on the road at around 65 it immediately started back. Maybe worse than when I took it in. I'm getting ready to drive from South Carolina to TX, FL, and Mass in jan and don't want this problem aggravating me all the way.

Got my truck about 4 months and 9000 miles ago (double cab 4x4 5.3 w/3.42) and seem to notice that I only have the vibration when I have a trailer hooked up. I have tried multiple trailers and it's the same, so not in the trailer. Took it to the dealer with the trailer hooked up, they pit on the service ticket that it was possibly an overloaded trailer. 3000 lbs max, and I thought these trucks were supposed to have the highest towing capacity they ever had. They also had something to say about my leveling kit being on there. And then proceeded to tell me there was a difference in mine and the 10 they had sitting on the lot that they had installed.

Nothing to the rear. Gonna have to wait until I wear this set of tires out before I do anything there. Probably go with some 285s when I do get some. Would love to set it up like my 2010 6.2 , but the road miles I put on now won't allow. This picture is the 2010 with about 4in front/ 1in rear and 325/60/18 BFG All Terrains.

These kits are fairly simple to install. Got mine from EBay. It was made by summit mfg. got this on because it was only $49-59. Very pleased with the quality being machined aluminum. Mine is the 2.5 but they also have a 3.5 in kit. 2.5 leveled mine out perfectly. There is only about 3/8" difference from the back now. Sent from my iPad using Tapatalk - now Free
