marbles 1965

Well went to another dealer and tech drove truck and said he heard clunk like I said but they "ALL CLUNK DUE TO DRIVE LINE SLOP"I asked why would a new truck have enough slop to make a clunk and what would it be like in 50k miles.NO ANSWER.But they would let me drove 1 on lot to see if it made same noise.Now this may sound dumb but isn"t there specs for the rearend that a engineer drew up and blueprints sent to the company to manufacturer the product.I AM AT MY WITS END AND RAM TRUCKS ARE LOOKING ALOT BETTER.Gm rep was to call me back this afternoon but no call this sounds like the dealer and everyone I have talked to about this new truck no answer on anything

Hello Marbles,

I own a 2011 Silverado, ext cab with 13000 miles, it does not clunk.

I had a Ford that I took to 4 dealers 7 times, and the steering still pulled
left. I filed lemon law and got a new truck for about 15 cents a mile that I had put on the one I had. The new one pulled left, but it got taken care of.

Get a new trans/drive shaft/rear end, or a new truck.

They (GM) should take care of this problem.

Good luck.

Try having the slip yoke greased real good. This is one area that causes clunks in the drivetrain. Mine did it real bad until I packed it with grease. It is worth a try.

tried grease on yoke, then a new put in nickel plate one,the play is in rearend.FROM past trucks I would bet 99.9% its in spider gears.Working with GM rep now hope we can get this Fixed.I do not think GM designed clunking into its design.On an other note check engine started flashing and it was dropping cylinders, on way home from work going to dealer tommorrow.
