Finally found the right Bearings - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Nima** · 10-14-2006, 07:46 PM

Well, after lots of delays and assembling and disassembling I learned in a hard way that I have to test fit every single part before putting things together. Finally I found the right bearings, race and seals for my truck. I am gona write some part numbers for those who may looking for these parts.
outer bearing: (comes with race)KB-11630-Z
Outer bearing race alone: NAPA 362-A
Inner beaing: (comes with race)KD-11786-Y
Oil seal: NAPA 28426
By the way, as usual I am confused about inner/outter bearing. I call the one close to the rear diff inner which are bigger. They are right under the seal. If I am wrong please somebody correct me.
Thanks for the people who helped me along the way.
Oh by the way these are close to final pics. Now I have to challange myslef ,again, by trying to bend some break lines.

Got to admit that's the first 3/4 ton rear disk brake setup I have seen. Very nice!

Nima - Spill the beans about the rear discs.
1. What rear end - Eaton or Dana
2. A kit or your own engineering
3. Pictures or diagrams of the caliper brackets

That sure looks good - Bob

It is eaton 3rd member on y 67 3/4 ton. It is the original axle. It is a kit from blackbirdscustom. I wanted to put the parts together myself but after getting prices and reading other threads, it would make more sense to get the kit since everthing is new or quality rebuilt. There should be a picture of brakets somewhere in my computer, I'll try to find it but you can also find it on the blackbirdscustomtrucks.com. My main problem was finding the bearing which are finally done. Also othet thing came to my mind, when I changed my front drum to discs the wheel studs changed to 9/16". My originals rear hubs had 1/2" holes. Instead ot drilling the hubs ( I am mechanically challenged

), I made a trip to j yard and picked up a pair of 71-72 rear hubs which have 9/16" holes. Now I have 9/16" all around
