Since we have the fuel tank mounting brackets painted and installed on the frame, I thought it would be a good time to start getting the fuel tanks ready (Also I knew one of us was going to walk right into one of these brackets and whack their ankle… ) So we started working on the passenger side fuel tank we got from Stan…

This tank is in great shape so all we had to do was clean the back and bottom of it, so my Dad went to work…

We finished by cleaning the tank with hot soapy water and some SOS pads and this is what we wound up with…

I found a guy locally who polishes wheels and fuel tanks, so the next day I met him to have him look at it and see what he thought… Over the phone he was concerned about the diamond plate, but after looking at the tank he felt it was in great shape and would polish out great. So I decided to have him do the tank.
The night we finished cleaning up the tank, Bigdogz posted a handful of parts for sale in the Classified Section. He listed a set of bud hubs for a Rockwell axle, so I got in touch with him to see if he had S cam brakes to go along with the hubs. Sure enough he did, so I decided to pull my axle in to check the bearing numbers.
If you remember, I bought a front clip from Stan a while back for the power steering. This was from N760TL-90680 and had budd hubs but no brakes. We planned on using this axle, but I left it outside covered up until I needed it…

I used the forklift to set it at the edge of my driveway but with the snow there was no way I was going to get it out of there with the forklift… So with the help of my Wife’s Yukon I drug it up to garage door!

And with the help of some large bars and my new wheel dolly’s, I was able to bring it in the garage…

Fortunately there was still a tag on it but it was hanging on by a thread…

After a quick Google search, I found two pages that decoded the Rockwell number…


So based on my tag which reads FF931 RDA X5, the first ‘F’ is for front axle, the second ‘F’ is for 12,000lb, the ‘9’ is for series, the ‘3’ is for large centers and knuckles, and the ‘RDA’ is for Wedge Brakes, Dual Air Chambers. I found a quick release valve on the front cross member, so I thought someone may have removed the front brakes, and sure enough they did! They had installed a ring to keep stuff out of the seal area, and you can see how the rust was buckling it, so they must have been removed quite some time ago… I also checked some of my factory paperwork for 760’s, and the FF931 was the stock axle in the truck. So after reading the code, we removed the hubs…

And then I drew a quick sketch of the spindles with the bearing and seal info…

So that’s it for now, more to follow…
