Double Cardan Constant Velocity (CV for short)joints allow power transfer through higher angles. My '76 Pantiac had one near the differencial giving it the appearance of 3 U-joints (one at front, 2 at rear) and no hanger. It failed in about 2 hours of actual driving time (on our way to a cottage), I sure knew there was something wrong.

By the pic of your truck sitting there not sagging and by the pic of that yoke, You had an oil starvation or a major balance problem. Since you should of felt a vib. way before that amount of damage was done my guess is enough oil wasn't getting to the rear bushing or There was a burr or nick on the surface of the yoke to tear it up. There should be some kind of warranty help on this. Maybe not full coverege but at least a percentage. That looks like a HD. 4l80E tranny. I've been out of the auto bus. for some time but the rear bushing and yoke material and set up have been unchanged for years. I've never seen damage like that before. Tell them I said it should have some warranty coverage, it should make a difference
There's TREACHERY AFOOT!!!
Thanks MCR. Forgive my ignorance but what is supposed to get oil, what kind of oil, how does it get it?

As the trans is operating a small amt. of oil is SUPPOSED to get to the once smooth surface of the yoke that is now torn up. Either by pressure from the trans oil pump thru a small hole in the bushing(like the main & rod brgs. in an engine), or by splash from the innards spinning.I find it hard to believe that oil wasn't geeting there. Was any work ever done to the truck previously? I'm still thinking something got in between the yoke surface and the bushing it rides in. Either from the outside from a sloppy previous repair,somehow some grit getting past that seal from a dusty road ect. or a chunk of metal from the inside.

Update: Service Manager called today and offered me 1/2 of my $800 back....covered under the "good will warranty". I said I want to know what caused the failure. He still insisted on my liftgate as being the problem. I told him that was not good enough and he got pissy with me and said he would request a technical evaluation. He called back shortly and said the GM engineer told him there was no way the tailgate caused the problem.
Now he wants the parts back to give me 50% credit under warranty.
Here is how I see it. I bought those parts, they are mine. I bought the new parts, they are mine. If he wants them he can buy them back from me.
He already lied to me once when he said that he has seen many other liftgates cause this problem. He said, "it happens all the time".
I don't do business where people are dishonest with me.
I need GM's number and I don't mean the local rep. I want Mr. Motors number himself.

Steve, Tell him he can have his parts back when he replaces them and puts a new transmission in your truck UNDER FULL WARRANTY. It is obvious by his response that he knows it was a factory issue. You have them by the balls brother, all you have to do is squeeze!
squeeky wheel gets the grease pardon the pun
don't give up fight it all the way Steve

"GM engineer told him there was no way the tailgate caused the problem."
That is EASY to see by the pics you posted...I doubt your truck dropped an inch from that thing, they better stand by their gvw and tounge weight claim, they are in enough **** already!
Steve, you should have asked the idiot to please explain to you how a two piece drive shaft will cause stress at the tail shaft of the transmission from the rear of the truck when the saddle bearing, which is "BOLTED" to the frame creating a permanent and non-movable location, keeps the front piece of the two section driveshaft always at the correct angle.

Tell him they can see the bad parts at the trial when your lawyer admits them as exhibits one and two for evidence.
The only way that gate can damage that yoke is by twisting the splines from the wieght, which it did not. Let this guy lie some more. You'll have full warranty coverage before you know it.

The service manager is paid to lie to you. They tried to change my dad's power steering fluid at 20,000 miles until I went down there. I'd take the 50%,have it repaired, then trade it. Those two piece driveshafts are crap.....the weakest link.
If everything was always done "by the book"....the book would never change.
Looks to me like MadeinUSA has it right...Looks like the only reason there's a U-joint behind the transmission is because of engine torque, bounce or vehicle flex, since the other end is bolted to the truck.Originally posted by MadeinUSA

There have been some changes to this story. So far I have recieved my $842 back that I paid to the dealership. GM paid half and the dealership paid half. But the promise of future goodwill warranty coverage has been denied.

Sight unseen the technical engineer from GM has determined the cause of failure to be lack of lubrication to the sleeve in the tail piece which caused the wear rapidly outside of the warranty period.

You will be losing the tranny in a very short period of time after the metal shavings have a feast on the clutches. The front pump will not be cheap to replace either when it goes. Either demand them to replace your whole tranny or rebuild the whole tranny. They are hanging you out to dry for a factory defect which by delaying longer gives them more room to deny your future claim being you will accumulate additional mileage.
Demand the number to the district rep and tell him you will not stand for a factory defect to not be fully and properly repaired. Tell him you know as well as he knows the clutches and the front pump are on barrowed time and are toast now with all the metal shavings circulating in the tranny.
Ask him how he plans to make this right.
Yea and that ain't even a trick question I sure would like to know what is answer is on that one.Originally posted by MadeinUSA

As I said earlier in this thread, and others have backed my diagnosis..You will need a new trans in the near future due to this ADMITTED factory defect. I would make them replace the transmission too while you are still ahead in the negotiation. If they refuse, Threaten to sue them, I guarantee you will get a new trans.
hey Steve I read all the replies and if the problem was lack of lubrication as they say I didnt see where they removed your trans to solve the lubrication problem. get ready to buy trans! you wouldnt replace a compressor that failed due to flood back with out solving problem would you?
