2005 Yukon XL differential gasket

[HaroldCallahan]

I would like to change the rear diff fluid on my wife's 2005 Yukon XL 1/2 ton today.

 

I checked at NAPA and autozone and they both say there is no part number listed for the gasket. I can see that there is a gasket from the factory.

 

I would like to do this job today, if I cant find a gasket then I will have to go to the dealer tomorrow.

 

I thought about reusing the old gasket, but it could tear when taking the cover off or maybe leak.

 

I went through this same thing with my 99 ranger. Nobody had the gasket listed, they said just use silicone. I did and it leaked. I finally found the part number for the correct felpro gasket for the ranger. I just give them the felpro number at checker now.

 

Anybody know what gasket works for 2005 Yukon XL 1/2 ton differential ?

Still didnt find a gasket yet, but found this interesting article about what can happen with the wrong gasket or silicone.

Found more on the missing holes -

I know that I use the RDS 55028-1 felpro gasket with the holes in my '88 Burb. I think that this must be the correct gasket for the 2005 Yukon as well. The rear end looks just like a 10 bolt to me.
