I’m looking for TSB info for a 2010 Chevy express. I’ve found very little info after hours of searching google. I did find a TSB describing the noise I have concerning the rear suspension. It’s a metal on metal clinck noise that I thought would be u joints, but the TSB I found leads me to believe it’s not the u joints. Anyone have all data access that can find more info and possible fix for the problem before I go ahead and replace the u joints?

whats the milage? U joints are covered under 5yr/100k powertrain warranty.
