4WD Front hub question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BigRed76 · 05-25-2015, 04:09 PM

Earlier today I tore down the front brakes/hubs on my K2500 to replace the rotors, and when I got everything apart I noticed that the right side had a shim on it that the left side did not. The shim was underneath the outermost piece with the dial in it. I'm assuming that both sides should have this shim correct? And are there supposed to be any gaskets or seals between the sections of the hubs? The last person to have this apart just put a thin layer of silicone, which worked fine, I'm just curious about the correct way these should be sealed up. Thanks for any info

(And no I don't have an assembly manual to look this stuff up)

That is one of two gaskets per side the factory used.
In this case the assembly manual would not be of any help but the service manual will be.
If you don't have it here is a link to a usable free copy.

Thank you for confirming that Tim. I suppose nobody reproduces these either huh?

#1 is the metal gasket shown in the pic and #3 is the missing paper gasket. Neither reproduced and difficult to find.

I was able to get the metal & paper gaskets on eBay. Thanks for the heads up DeadheadNM.
