GMC Yukon Vibration Problems
I have already poured over the forums and found several other threads involving what seems to be my same problem; however, I'd like to pose my problem and get a firm grip before visiting the dealer.
I have a 2007 GMC Yukon SLT with 17 inch factory wheels, P265/70/17 tires--no aftermarket additions, totally stock. I am having annoying vibrations after I get over about 71 mph(it also seems to have some float/vibration problems around 45-50 mph). It does seem as if the vibration is coming from the back but I cannot be for certain. The vibration occurs whether in 2HI, auto, or 4HI. The odd thing is that when I have a full load of people in my Yukon (i.e. 5 or 6) the vibration seems to completely go away. I took it to the dealer today and had them do a road force balance and it did seem to help but only in the slightest sense. From reading the forums it appears this does not seem to be an isolated problem--has a solution been tagged or at least the problem isolated? I greatly appreciate any and all help.
