Title: 1973 to 1977 1/2 wheel hubs
Post by: nickpc87 on July 30, 2019, 07:18:36 PM
I have a 1976 k10 with one piece hub and rotor assembly. I cant find new hubs anywhere and my rotors are shot. Has anyone else dealt with this?

you should be able to get those at any parts store that is all one piece while you are at it get new bearings and seals.

The hubs for 73 to 77 1/2 are not the same as late 77 to 87. The dimensions and bearings are different. I learned the hard way because i bought parts for an 86 k10 and they didnt fit right. Then i got the numbers off the frame and its a 77. 73 to the first half of 77 is different then the second half of 77 to 87.

I havent seen one piece rotor and hubs anywhere. I can get rotors for a 2 piece setup but ive only found one place that has hubs available  and theyre used and 200$ each. I cant be the only one to run into this problem

Havenít seen any early small bearing hubs out there either other than used.
Canít say I even knew there were one piece 4x4 hubs out there.
Guess they were available as a replacement at some time.
My 74 has the original hubs and are 2 piece.
Youíll need the spindles and hubs from a the later larger bearing setup.
The inner bearing is slightly larger IIRC.
