I just discovered that I've got an axle seal leaking on the full floater on my '77 F250 2wd. (dana 60 I assume?) I'm going to do both sides and inspect the bearings and whatnot. What type of socket do I need to remove the lock nuts and adjusting nuts on the hubs? The only socket I've got is for newer trucks with the 6 prong style. I would like the have all the tools I need before I begin tearing it apart. Thanks
I just did my '76 F250 rear brakes and seals last weekend. Mine's a Dana 60 rear axle. It's a 2 9/16" 6pt with rounded corners. Napa will have the socket and I think it's an OTC-1928. Search online and be sure of the part # please. Also, get the lock washers #635-1100 from Napa for the spindle lock nuts. You'll need them. I'd do the shoes while you're in there. Good luck.
I appreciate the help Mike. Napa's gonna love me. Aside from the 250, I've gotta do the axle seals and shoes on my '71 Chrysler and shoes on my Dodge Stratus. I'll be seeing drum brakes in my sleep.
Had to drive to a distant Napa to get the socket without ordering it. KD tools, $23 made in USA. Almost did the job in the parking lot of my apartment, but forgot to bring home my 1/2" to 3/4" adapter for the socket. VERY glad I took it to work. Water had been in there at one point, did a number on the inner bearing, it was stuck to the housing. It would have been quite a task replacing the bearing races in the drum without an air hammer and a shop press. I changed the gear oil too, so truck is still sitting on the lift allowing the RTV on the diff cover to dry. I also match mounted and balanced my crappy 16.5"s. One of them didn't have excessive runout, but took 8.00 ounces on one side! I had to use pound on and stick on weights! Can't wait to try it out on Monday. It roared like a lion and rode like it had square tires before. I'd be happy if it rode like oval, or even octagon tires now.
I told the parts man that they were heavy duty as a guess based solely on the fact that it has twin piston calipers up front. The bearings and seal he gave me were correct. Haven't replaced the shoes yet until I'm sure its not going to leak anymore. I'd rather pull it apart again and have to buy another $5 seal than waste a set of shoes. Did you find that the HD drums went with the twin piston calipers up front? That would be good to know for when I do buy shoes. I'm assuming its got the heavier duty stuff since it says F252 on the door tag.
did you check the seal surface, if there was a groove in the surface, it may still leak
I had to put sleeves (.010 thick standard bearing parts) on both of mine as they had grooves

You are correct that it's a heavy duty suspension setup. F252 = 7700 GVW. Ford considered F250s higher than 6800 GVW HD.
My mistake - I thought mine were an option. My 250SC has a 6600 GVW and a 4-bbl on a 360. I've been in the habit of taking in the old set or brakes (or whatever) with me when I get replacement parts.
I don't know if it is considered HD or not, but my '76 F250 SC with DP calipers in the front which is an 8100 lb. GVW truck has 12 x 2 1/2 shoes in the rear.
Thanks Jermafenser. That will be nice buying the right shoes on the 1st try! My sealing surface didn't have grooves, but it was kind of corroded. I cleaned it up with emery cloth. I've driven about 50 miles and so far so good. I didn't know about those sleeves though. Thanks brownfoot. I'm keeping an eye on it, and may have to get those sleeves before I do the shoes.
You may want to replace the locking plate that goes between the nuts. Reused one one too many times and it broke alowing the nuts to tighten to the point that the wheel locked up. Ended up with a hefty tow bill and a real mess to disassemble and repair.
