Grease slip yolk cluk how to?

[08grey]

Can anyone share what they did to grease or lubricate their slip yolk to solve the clunk?
I have searched and i cant seem to find specifics?
What i would like to know i....
what type or grease? how was it allpied? will it mix in the transfer case? what method did you use to get the grease in there? ect.... is there a difference in what should be used for the different transmissions and years?

help me please guys, i am going to do my brakes this week and this clunk is driving me crazy.

btw i have a 08 yukon denali

Anyone?

From what i`ve read there is a nickel plated slip yolk that solves the problem.

Grease will fix it for a while but the clunk will return and if you keep greasing it you will contaminate your fluid.

I checked around and advance auto sells them for about $170

I'd like some info on this as well. Our escalade has been having that clunking problem for quite some time, and i need to get it sorted out before i sell it.

Is it two of them I have to change? The front and the back?

Just the rear one will do it.

Do you have the proper part #?

 

[08grey]

So I have searched and searched. I found guys who did the bouncy ball. Guys who greased it. I can't seem to find a definite part number for the mickle plates yolk. Come on guys there are allot of denali's on here. What did you do to yours?

It looks like the reason you may be having so much trouble finding the part number is due to the fact that your truck is not part of the bulletin. At least not yet anyway. I am looking at the bulletin and the newest part numbers are 12479384 for the yoke and 12479126 for the u-joint you will need to go with it.
These may still fit your setup though.

Can you geese the 6l80 or will the grease mix with the tranny fluid?

Is the nickel plated yolk an OE part? If so PM the gm parts member in this forum with your vin # and they should be able to get it for you.

These part numbers are for NBS trucks

From what I found in the NBS trucks the tsb says not to grease the 4wd trucks. Which I am guessing May be the same for the nnbs awd trucks.

You are correct sir. Just noticed that. It came up on pro demand under his truck build, but didn't make much sense. Oh well.

I called the dealership I usually work with today to see if there was a OE nickle plated yoke for the 08. He says there is no listing, but I also didn't have a VIN to work with. Of course he was being an ass today and I was reciprocating the attitude.

 

[08grey]

Lol. Sucks to work on dead Presidents' Day. Can I pm you my vin?

 

[Mechahead]

Yeah, absolutely, I want to see if there is a way to fix it to. I will call another dealer I frequent as I don't think my business will be welcome there for awhile.

I am curious about this...

Can someone describe this "clunking"?

I have a clunking sound that seems to be associated with the vehicle downshifting upon stopping.

 

[Pockets]

Mine use to do it going over speed bumps. As soon as your back tires would come off the "bump" you would hear a clunk. What I did was take the drive shift out and just greased the yolk that way. That was over a year ago with no noises/problems since.
