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?

I thought that issue was solved by putting in a thicker spring pad . The plastic inserts that snap into the springs anyway .

Thanks for posting the info. I’ll take a look at the spring shackles before I attempt u joints. U joints are easy and cheap enough to do at home, it would cost me more in fuel to go to the dealer and back.

GM u joints are much higher quality then the 10 dollar part store option. Ours are almost 100 bucks over the counter, plus if you damage something doing it yourself the warranty on the part is voided. My .02 would be if it has less then 36k on it take a ride to the dealer.

Im not sure if GM still does this but a lot of their U-joints are set in hard plastic instead of c-clips. Unless you have oxy-acetalyne at home than the leafs will be easier and the u-joints pretty much impossible.  
The ambulance I ride in everyday had the shackles replaced under warranty. Its an 09 with 80k and weighs 8k pounds before patients, paramedics, passengers. It is a 3500 Duramax diesel and still has the factory U-joints. She gets driven hard too!

I do stop and go, forward to reverse without coming to a dead stop. Not to the point where the tires lock up. Just hit 89k today, and I know for a fact it’s the u joint now. For the first time it started making the “eee-err-eee-err” at slow speeds. I’ve google how to replace the u joints and people have been doing them with a small propane torch. From what I’ve read it’s just a nylon retainer.

like John said it’s easy just burn the nylon out first then I like to use a balljoint press to push the caps out. Like I said before if it’s the joints they are going to be free at the dealer and a higher quality part then what you get from advanced or NAPA.

I might end up bringing to the dealer but not just for the u joints. I’m pretty sure the g80 locker is fucked, I haven’t felt it engage at all this winter, and I’ve been on some icy driveways. Last year you could deft tell when it locked, it would bang then you could hear the tires scuff when you turned onto pavement. I know the diff is drivetrain, it should be covered right?
