63 k10 rear axle seal inside drum

[Builtlikeatank634X4]

Hello
I'm new to this forum .. I'm finally starting to repair a truck I bought that was sitting under a tree .. 1963 k14 .. 90% original .. Was ordered from factory by a school district and was equipped with a snow plow .. Plow is gone .

I'm starting with the brakes so it will stop cause the engine runs strong .. I removed the rear drums and one side has a heavy syrup kind of glaze all over the shoes and inside the drum .

I looked behind the axle where the wheel mounts and inside the brake backing plate and there is a 1/2 inch gap compared to the opposite side axle .. I have the repro factory assembly manual but it does not cover brakes or axle diagrams ..

I took these photo's that show the gap in first two compared to the third photo of the other axle .. My concern is this a damaged part that is obsolete and will I have to replace the whole rear end ?

I'm finding out with the front brakes how many auto parts stores don't carry the correct springs or brake shoes and there inventory lists the shoes as universal front and rear .. But mine is the k10 with a Dana 44 with warn M8 locking hubs

Any help and advice would be greatly appreciated until I purchase a factory shop manual

With respect
Thank you

Rockauto carries just about all you need to rebuild the front (Dana 44-5F) and the rear (Eaton H033) brakes.

Well now I know why I got the truck for such a low price .. The differential pinion shaft locking screw is broken in half and it looks like it's gonna be a whole lot of fun trying to extract the broken half without removing the entire rear end .. Has anyone had the pleasure of this misfortune before and not put a stick of dynamite in the gas tank ?

Can I get a ray of sunshine in my now dismal truck adventure ?

Good news
I found online a broken pinion lock bolt extraction kit .. Straight up specifically designed to extract broken pinion shaft bolts .

Fabbriassociates.com

$35.90 includes new lock bolt

I was going to tell you to pull the cover and look, but you are a step ahead of me. As for the broken lockbolt, I just went through this, although much worse. http://67-72chevytrucks.com/vboard/s...d.php?t=679790 The lockbolt seems to be broken more often than not. Please do not start beating on the pin or trying to get it out until you get the rest of that bolt out. From what I have read the extractor kits work pretty well.

Not that you have the cover off do you have a c clip coming off, or can you tell why that one shaft is sticking out more than the other?

[Builtlikeatank634X4]

Oh man
Just looking at my broken bolt was a kick to my nuts .. I called 4 differential repair shops and not one of them said they've dealt with a broken lock bolt .. I spent 15 yrs machining production tooling .. Anytime there was an issue with retro fitting or fabricating I would go look for the old Grey hairs cause you know they've been there and done that and made a tool out of an old Allen wrench .. Lol

The second shop I called the guy said I should start beating on it till it sheared off .. WTF !!
I've ordered the extractor kit .. I can't pull any axles until I get the pinion shaft out so I'm gonna wait .. But it sure the shaft seal is wrecked and deformed from previous owner packing that gap with horse hair to stop it from leaking.

Truck has been sitting on the side of the house for almost ten yrs. Or you would have heard about a guy walking around with a rear differential hanging out of his mouth .. Lol

I'm gonna keep marching on

I've had some luck in the past welding another bolt onto the end of a broken bolt, then turning it out. However this may prove more difficult on gear oil soaked steel.

[rickywideglide]

had this happen on a chevelle bolt must of broke then pin that runs thru spider gears dropped out,when i opened cover all spider gears were in pieces

[63burban]

I would just replace front and rear axle assemblies with 1973-87 axles. They are more parts friendly and also better gear ratios

[Builtlikeatank634X4]

Funny thing
This morning I was cleaning up the back plate and just getting things all prepped for the busted bolt job and I notice I have 2 different axles .

The right side looks like it's the original cause the left side looks like someone welded a beverage coaster onto the end and put six lug bolts through it .. Lol

That explains the big gap .. Well after yesterdays kick in the nuts I must not have been paying attention but I am now

New Axles .. This is my first classic truck .. Can you shoot me some info on axles that are compatible with my differential ? .. One thing I liked about it was its stance .. Looked like a little pitbull

[63burban]

1973-87 axles will work great, front axle should bolt in, rear axle you may need to move the mounting pads. I believe Captn Fab is better versed at these swaps.

[MitchFloyd]

There are plenty of Eaton HO33's still around. I'd look for a C10 Eaton rear and just do a rear axle swap. that way you don't have to mess with the front. Plus, everybody that's modifing there C10 takes out the old rear anyways. So you may find one already pulled.

[argonaut]

Agreed. Swapping in a whole new rear axle assembly week be the least painful way to fix your problem.

[jdl71]

If you to swap just the rear make sure it is the same ratio as the front if you ever plan on puttng it in 4wd.

[Builtlikeatank634X4]

Awesome awesome and awesome

However, the bank / wife would be all over me .. And not in a good way .. If I pulled the whole rear end assembly .. I just want to replace the axle seals so I have a road worthy and full function truck so when I do my complete teardown and semi-pro frame off / up restore with some suspension modifications .. The wife will give a seal of approval .. After 30 yrs Of marriage its all part of my master plan

Like I said .. Its been on the side of house almost 10 yrs .. The engine is a 327 hi-po 1964 correct with Rochester 4-jet carb .. Not quadrajet .. Turbo 400 trans .. Many times it was like stormin Normandy beach getting her mouth shut .. So it must be love

So axle swap if I'm successful with the extraction kit .. If not .. Complete rear end

Sound good ?

I don't know what an extraction kit consists of but you can go down to your local automotive parts jobber and get an eze- out that would work for a 3/16 0r 1/4" drill bit or what ever size drill bit that the eze-out is designed for not much money. drill out the broken bolt to the right size and put in the easy out. tap it with a hammer to get it to bite . put a wrench on it and back it out. the trick is to get the hole centred properly. so start with a smaller drill to start just in case you are off a bit and then go bigger to take the largest easy-out that you can put in without drilling into the threaded part. apply some loosen all of whatever flavour that you have first before you satr. some times a little heat helps as does a CO2 fire extinguisher. Be careful on first trying to remove it that you do not break off the eze-out as that will take more skill to remove. when drilling the hole have the drill on slow and have a sharp drill bit. slow is advisable esp. if it was a hardened bolt. if all fails you can always drill out as close to the edge of the threads and go in with a small cold chisel and hammer and pick it out. just have patience and you will get it.
another thing about these rear axle seals or bearing is that they run on the axle shaft themselves and wear the axle itself. this was one of the reasons why I went to full floating axles on mine
stock drums frt and rear I believe are the same. brake shoes may be also . just compare frt and rear sboes.
removing broken bolts may look like a PITA but it is just a straight forward operation

The extraction kit comes with drill guides .. Basically some socket head cap screws with a hole drilled through the center .. If there is enough thread .. Screw in the cap screw bolt and now you have a centered drill guide .. Also need an extra long drill bit to clear the differential .. This way I don't have to remove the read end .. If it doesn't work .. I still have it all together and when I pull the whole thing off I'll have the new one to replace it .. I'm gonna video the whole operation and upload it ..

[argonaut]

I've never bought one, but don't they make reverse rotation drill bits? I've never had good luck with those extractors. They ALWAYS snap off leaving the tip in my bolt and then bad goes to worse.

I thought I saw a set of 6-lug axle shafts on craigslist in the IE. Might want to check so that you can swap them in after you figure out the broken bolt situation. Also check the surface of the axle shafts where the seals ride. Over time this area can get a little groove worn in it, and then they'll still leak even with new seals.

[argonaut]

I think these might just spin it out as you are drilling. Use a center punch.

The pinion bolt is bottomed out and the kit comes with everything in reverse .. For $40 some bucks I'll either extract the broken piece with a kit specifically designed and engineered to remove broken pinion locking screws .. OR .. I paid $40 admission to start looking for another complete rear end .. I'm doing all this on the RV storage rocks up the side of the house .. Whole lot of fun .. Lol

[jdl71]

I'm sure you've read all the same stuff I did about this, but I do remember reading where some have taken a dental pick and root around in the hole and got the bolt to spin backwards just by catching the edge of a broken thread. I'm curious to see how the extractor works also, when most people see "extractor" they are thinking easy out and there is a lot more to it than that.

[Builtlikeatank634X4]

That's way to scary for me .. Are you spying on me with a satellite or a drone ?.. Lol .. I let the dog out to the yard and for some reason I went into my cab and saw the little jewelers tool stabbed it in the hole with a counter clockwise rotation and SHAZAM !!!!! .. Hanging on by its final thread

Yes I'm sure it's an ez out .. Did you look at the website ?

www.fabbriassociates.com

They call it an extractor kit .. Thumbs up to the guy .. If I had a drill press I'd make the drill guides myself .. But with this locking bolt break he nailed it .. If I ever get a broken bolt with some exposed threads I'm drilling out a socket head capscrew as a centering drill guide.

Do you happen to have any dimensions for this shaft / axle seal landing ? .. Max / min O.D. ?
The surface itself doesn't show any deep wear lines and the lipseal just seamed to be packed up with mudfish debris causing a breach in the seal integrity

No drone, but that is funny.

Yes. I looked while I was fighting mine. What I meat was it's more than just an ez out. It has the drill guides and I thought it also came with an extra long drill bit.

No. I have a 12 bolt. I do have a factory shop manual for '63 though I will see if any of those specs are in there but I kind of doubt it. I'll let you know.

[Builtlikeatank634X4]

What is this splash guard looking thing called that's located on the back of the wheel flange held on by the lug bolts ??

Now I know why the inside of the brake drum was sprayed and covered in maple syrup

Please tell me still sell them or would I have to make one
