Remove 1 ton rear brake removal
 

Need to replace some leaking wheel cylinders and get the brakes buttoned up. Anyone have a tutorial on how to remove these rears? 39 tonner

!st, place a small drain pan under the end to catch the bearing oil. Next, take off the 8 bolts around the end of the axle. A good whack on the end will usually pop the axle loose. Inside you will find two large nuts with a lock tab holding them. Often times there is not clearance for a normal socket in there so then you need to get one of the thin steel sockets just for this. You may find the last guy took it off with a chisel. Once those nuts are off, the bearing falls out, and the drum slides off.

Should be 3 screws holding drum to hub. If you can't take those out, remove rear axle shaft, bearing retainer nuts, bearings, and slide whole hub/drum off. The axle flange has cone washers, which require you to pound on flange to get them out. May have to back off shoes if the drum has a lip.

Better to focus on removing flathead screws and slide drum off. Panther pee and an impact screw driver will be your friends

Ok, got it to this point. I'll need to get a socket that fits this nut. Is it a common size? Largest I have is a 36mm from a Dodge Ram but its no where near large enough. Also, is there a torque spec when reinstalling the nut?

Also, I assume the gear oil is normal as its a free floating setup or is there a seal that should be replaced while this is apart? I'll also need new gaskets for the axle to hub, where can those be sourced?

This is what the socket looks like.

awesome, I'll run out in between the rain showers and get a measurement for size. THX

2 3/8 sound correct?

Re: Remove 1 ton rear brake removal
 

When you get the tab bent up and can get the nut off & the lock plate off, could go tighten the inner nut to observe the amount of adjustment, probably less than 1/4 turn. Then if cone and cups look good know what the adjustment should be. I always went snug and back off 1/3 turn, but that was big trucks.

Re: Remove 1 ton rear brake removal
 

I had one of those large sockets that I used for the full-floating hubs on my vintage dirt modified. I got it from Speedway Motors, but that was almost 30 years ago.

Re: Remove 1 ton rear brake removal
 

Ford actually supplied these sockets in tool kits. Hard to find. I have one and traded one to a friend. Had the M for Moore forging.

Re: Remove 1 ton rear brake removal
 

years ago many of the auto parts stores had a variety they would loan out to get the job done. Probably not any more in this world today. 4x4 guys always have them, any of those in your neighborhood ?

Re: Remove 1 ton rear brake removal
 

Small world, I'll bet this looks familiar

Re: Remove 1 ton rear brake removal
 

I should have a NAPA number for the rear oil seal. I will be in the shop in a while and look. I usually make a gasket from a cereal box for the axle flange. Smear both sides with your choice of sealer.

Cool beans, hope it’s happy there, this best place to get info, & van pelt sales.

Re: Remove 1 ton rear brake removal
 

Got it all apart and found the rotted wheel cylinder. I'll clean everything up before assembly. Do you recommend painting anything ? What type of lubricant goes on the moving parts, can I use disc brake lube that I have?

Re: Remove 1 ton rear brake removal
 

I used to use Lubriplate #110 brake lube. Not sure whats in it but a small can has lasted me most of my life.

Re: Remove 1 ton rear brake removal
 

I have a can of brake lube, was bought and used for disc brak backing plates and glides but I assume it should work.

Re: Remove 1 ton rear brake removal
 

Its probably similar to what I have here, "Sil-Glyde" , a napa product kinda like vasolene but silicone based I assume. Good stuff to have around.

Re: Remove 1 ton rear brake removal
 

That's correct. See attached photo of Ford OEM socket

Re: Remove 1 ton rear brake removal
 

Attached are the pages from the 1939-48 Shop Manual that describes the procedure for removing the Brake Drum and resetting the loading on the bearing after the removal. My apologies for the upside down page 2 image.

This is the socket needed

Re: Remove 1 ton rear brake removal
 

I looked for the piece of the cardboard box with the seal #, but couldn't find it. I remember it covered a lot of years.

Re: Remove 1 ton rear brake removal
 

Thanks guys, you've been a big help. I was able to pull everything apart and get the needed part numbers from the wheel cylinders. Have all new wheel cylinders and flexible lines ordered as well as a new master cylinder. hard lines look to be in good condition, but I may blow some brake cleaner through the lines to get out any gunk that may be in there. Time to get cleaning and painting! I may order one of the bearing sockets to ease in the assembly but I was able to remove the nuts with a slight tap and a punch.

Re: Remove 1 ton rear brake removal
 

@expavr, Thank you, those scans helped with my question about tightening the hub. I did order myself a copy of the manual for future use.

I see that Fel Pro makes rear axle gaskets, but their online parts ID system only goes back to 1960 vehicles. Anyone have a part number for them?

Re: Remove 1 ton rear brake removal
 

Those gaskets for the axle shafts are darn near universal. If you have local parts store with some in stock for nearly any 3/4 ton pickup axle, like a modern dana 70 or dana 80 they might fit. bring a paper tracing along with you, or just make them

Re: Remove 1 ton rear brake removal
 

great idea. I have one that's in decent enough condition, I'll take it to Napa and see if it will mate up to something they have.

Re: Remove 1 ton rear brake removal
 

Got her all cleaned up and ready for installation.

Re: Remove 1 ton rear brake removal
 

Looking to replace these axle end to hub gaskets but not finding anything in the shop manual. Anyone recognize?

Re: Remove 1 ton rear brake removal
 

I think the part number is 61-1144.
That gasket looks home made.
Did some more searching and Ford changed the number to A8TZ-1001-B,
old NAPA # J26253, Fel-Pro 2931. Looks like most parts housed have them.
