They showed me that the final bag alignment was the best they could do and that it was "in tolerance" for the bag. I believe them...as I've looked at other trucks with so-low...the bags are also leaning a bit.

The engineers rode with me to a local tire dealer who replaced another G647RSS on the rear...which had a bead that was never seated at GM. They double checked the alignment and balanced everything again. The manager there and the engineers at Monroe said that UPS or some outfit had given up on this particular GM tire because they had sidewall consistency issues. I begged them to take the new GY's back against 4 Michelins. No luck. At $300 a pop, I wasn't going to spend $1200 to fix GM and Goodyear's issues.

Unfortunately, the ride home was another exercise in avoiding 65 mph. Put a trailer on it at that speed...and it is undriveable.

Almost home, I also noticed that the fuel filler doors were resting on the torx fasteners and not the rubber stops. They were banging the body and chipping paint off the fuel door and truck all the way home. I have sinced removed a couple of shims to get them on the rubbers, but the bed vibration is to great, and the fuel doors are still getting out to kiss the body. Crap!

So 900 miles later...very expensive fuel bills...a hotel stay...I haven't gotten anywhere with the disabling vibration. All I can say is that it is worse on old asphalt roads and much better on concrete. I was going to alternate letting air out of rear tires to see if I could make it go away by partially deflating a rear. \\\

I'll say it again...Monroe should be admired for taking this time to work on GM's issues. They sent me a bottle of touch up for the fuel doors, but I have much more work to do.

The GM dealer is ignoring my emails and never paid for the alignment and tire swap that he promised to pay for.

And they wonder why they are in trouble.

I don't know why you continue to bash GM for Monroe and Goodyears problems. They should give you touch up paint for the fuel doors considering it is their issue not GM. The box sides and everything attached to them are Monroes responsibility not GM. Tires are warrentied seperate from the vehicle warrenty, so try and get a Goodyear dealer to warrenty them. I own one of these trucks so I know who is responsible for what. If your going to be a GM hater go some where else to do it .
