Rear leaf spring mounts and frame rusting through causing a safety hazard. Chevrolet doesn't offer a repair part nor does the aftermarket. The internet is ripe with other owners experiencing this or similar issues. The consumer stated there is frame corrosion specifically rear frame shackle mounts and lateral supports. The contact believes that the failure comes from the frame being made with the wrong metal thickness or metal that is not rust-proof. The vehicle was taken to a specialty shop to weld the frame, but the contact believes that is not the best way to fix the issue.

I own a 2006 Chevrolet Colorado with 14,000 miles on it. I have taken my truck to the dealer on at least 5 occasions complaining of a terrible vibration. The vibration is horrible from 40-55+ miles per hour. The dealer has so far replaced the 2 front tires, replaced the air inside the tires, rotated the tires and most recently stated there is nothing else they can do. After the last visit, I said there is something wrong with the truck and you or GM are going to have to step up and do something. This is my only transportation and I am very nervous about driving the truck with this terrible vibration. Please let me know what else I can do. I think a recall is in the cards, either to replace the all the tires or make modifications to the truck frame, etc.
