This is the wheel and hub on my 1982 GMC one
ton. This is a Dana 60 axle and I couldn’t really
find any awesome videos on YouTube showing how the hubs come apart.
So I’m going to show you. When you get inside, there are nuts, hub nuts
in there that you need a special socket for. This is one that I bought, it’s made by Lisle.
They seem to make good sockets. There are a couple of different styles so
you need to check it out before you get into your project really deep.
I’ll show you how you can check it before you have to lift the vehicle off the ground.
This particular socket is part number 29900. I bought it form RockAuto and they do have
several other models so make sure you get the right one.
I do want to tell you guys that I am not a professional mechanic.
This is actually the first time that I’ve gotten into a Dana 60 hub,
so make sure an do your research. There are several different kinds of Dana
60’s so this is just a general guideline. Turn the locking hub to “free” and then these
six allen head cap screws come out. It’s a 9/64 allen wrench.
On each side I had a broken allen screw. You can get replacements from Home Depot.
I was not able to find them at Lowes. It’s a 8-32 by 1.5″ stainless steel
You take out the six and the hub cap (lockout) just pulls off and that’s what’s inside.
Once you’ve got the cap off, you need to take this Phillips head screw out.
That just retains this center cog. This has a spring behind it so don’t let it
fly out on you. Once you pull the center cog out, you need
to take this snap ring, this internal snap ring out.
It just pulls out like that. Watch your eyes.
Wear eye protection. Next you need to take out this big snap ring
that goes around the whole circumference here. It holds this center part in.
It’s difficult to get out. Just use some flat head screwdrivers.
It’s a little bit frustrating but it will come out.
Starting to get the end out here… It’s difficult.
What I do is pry this first tip in towards the center and then pry the inside of the
ring up. It’s not easy.
Once you get it started, just kind of gradually go around the outside and gently pry the inside
edge out. You don’t want to bend this up.
And there it is. Finally. You’ve got to be patient with this.
That took about 5 or 10 minutes just to get that out.
Anyway, that ring comes out… And, then this center section should come
out. Easier way to pull it out is to take one of
the locking hub screws and thread it in to it’s original hole and
then wiggle it out. Everything that we’ve done up till now you
can do with the truck on the ground. You don’t need to remove the wheel and tire.
I took one of these apart a few weeks ago to figure out what hub socket I needed.
This is the axle. The spindle is right around it and then you can see the locking nuts around
that. My particular axle has the four notches on
the locking nuts. That’s where this huge socket comes in. It
fits in there. There are other sockets and nut styles.
I believe there is a six notch one so you might want to disassemble this just to this
point to see what socket you need before you dig real deep into this project.
This is the backside of the caliper. This is the bottom. Here’s the hub out here.
We need to remove this allen head bolt so that we can get the caliper off.
After you get that out, you can tap this plate out.
This plate will slide out that way. So this is the piece that came out of here.
This is the spring that sits on top and it slides between here.
We pounded it out this way with a hammer and chisel and that will allow the caliper to
come off. Back on the front side…
Since we took the plate and spring out from down here,
we can get the caliper off. Make sure you wire it up so it doesn’t put
a lot of tension on the brake line. We don’t want that.
So I’m just going to hang it here from the shock mount.
Now it’s off. You’ve got a little more access to the hub and brake disc now.
Now that we’ve go the brake caliper off we can work on getting the spindle nuts off.
You’ve got to take your big socket and fit it in the grooves in the nut.
I’ve already loosened these. They basically just screw off.
Well, the outer one is in there. Now you’ve got a locking washer with all of
these holes in it. It’s difficult to see but right up in here
there’s a pin. It’s a tiny tiny pin that sticks through that
locking washer and into the back nut. That keeps that back nut from moving.
We’ll take the washer out here. You can see all of the little holes.
There’s a little tang here on the inside and that fits in this grove in the spindle so
that this lock washer can’t move. There’s a little pin right there.
It’s kind of fragile. Just make sure you don’t shear that off.
Again, you take your socket….. Make sure it fits in the grooves in the nut
and just back it off. When you get the inner nut off you can see
the little pin sticking out. Sticking out right here.
Now that we’ve got both sets of nuts out, we should be able to pull the hub off.
The disc will come with it so it’s probably a little bit heavy.
There you go. It is a little bit heavy so just be careful.
You don’t want to scratch up the spindle or the drive shaft so be careful with that.
Here’s another shot of the spindle after the hub and disc have been removed.
You can see again, this is the slot that the locking washer fits in.
Just the surfaces that the seals ride on. Make sure they’re all good.
These nuts here should allow you to pull the spindle off.
I believe there’s another bearing inside the spindle that the drive shaft rides on.
Here are all of the parts again that we took off. Laid out.
I’ve got the other side started. Here’s the hub and the brake disc that we
just took off. You can see inside there
There’s a bearing on the front side and there’s also one on the back side.
I haven’t taken them out yet to inspect. If you’re doing a brake job, you need to separate
the hub from the disc by pressing these studs out, down through the
hub and the disc. That’s how they’re held together.
Here’s the back side of the hub and disc. You can see the backside bearing and also
a seal right on the outside edge here. And these are the wheel studs that have to
be pressed through in order to separate the two halves.
