Can anyone please help with clunk Tsb

[08grey]

So while getting my bbt right with Justin I realize my slip yolk clunk is getting bad. I have read allot about it and it seems there are two fixes.

Grease the yolk which eventually makes the grease mix with the fluid which I have read is not advised.

Get the nickel plated yolk by which there is a service bulletin for.

Does anyone know where I can find the Tsb for a 08 denali 6 speed for the slip yolk clunk??? Truck is under warranty for only two more months.

I dont know if TSBs will help as well. Im in the same boat as you with my 07 Nali. I am trying to find the specs for xfer case back lash. I seem to have a good amount of play.

"Do these service bulletins describe the issue?

08grey,

I am sorry to hear that you are experiencing an issue with your vehicle. Private message me your VIN and I can check to see exactly when you are still in your warranty by date and mileage. Also, I can check to see if you have any open recalls.

Safe travels,

I'm actually back on here looking for the thread I started with the exact same issue. From what I understand and what was replied to me on here, it's the slip yoke that needs greasing. I just had my truck in and asked them to do mine and it's still not fixed. Still trying to figure out if they even fixed it to be honest. Or tried to fix i should say.

When I first mentioned it to the service advisor, he told me that my truck doesn't have a slip yoke. he said they stopped using those a long time ago when they stopped using two piece drive shafts. I was automatically leery of this comment since my truck does have one. hahahaha. Needless to say the TSB's posted in this thread look good to me and I will print them out and take them with me when I go to pick my truck up.

Good luck.

tights24,

If I am reading this correctly, I see that you have a concern with your dealership. I am interested in this concern and what exactly brought you into this dealer. Please private message me the details.

Thanks,

When I am accelerating from a stop, my truck feels to slip for half a second. Best way I could describe it is like putting the truck in neutral (while stopped), foot off the brake pedal, and shifting into drive. That happens each time I accelerate some-what hard from a stop. Could it be the slip yoke?
