Hub rebuild resources 72 K25
 

Hello, I am looking for resources to show disassembly / assembly of the 4x4 hubs on my 1972 GMC K25. I have searched all topics here, or so I think, to no success.
Work completed on the front end so far is ball joints, pitman arm, drag links, and power steering box, tie rod ends all replaced.
Next on the list are the wheel bearings as it definitely appears they are in need of replacement, and obviously hubs need to be removed and replaced to do so.
thanks in advance for any help!

Those hubs are the Dana Spicer external type face tooth design used from 1970-early 1977. The K/5 and K10 hubs are the internal type face tooth design used from 1968-1980.

They are easy to take apart. I don’t have any exploded views but basically all it is to get them apart is a snap ring or two and the Allen bolts. There’s really not to much to it once once you get the dial housing pulled off. Lube them up with a light film of gear oil and not grease when you put them back together. That will help to keep them from getting stiff in the winter.

Awesome thanks guys for the info!
Exactly what I'm looking for. Everything I've seen on these it seemed a bit intimidating but reading the attachments it doesn't look too bad.
Assuming once the hubs are dismantled and callipers removed the wheel bearings should be fairly straight forward? I've done bearings on other trucks so I'm aware what that's about.

Yes. You'll need a spanner socket to get the large nuts off. Other than that, pretty straightforward.

Correct and my local oriely auto parts sells the socket you need for less than $20, hopefully you’ll have the same luck.
