Can someone tell me how I replace the brake discs, aka how do I remove the old ones? Do I need to dismantle the bearing hub, or is it just to remove the caliper and carefully knock the disc free from the hub with a rubber hammer or similar?

The brake disk is part of the hub assembly. The two of them are held together by the lug bolts. Pull the hub and disk together. Drive out the lug bolts and the hub and disk will separate.

 

Ok, thanks.

But is it diffecult to remove the hub assembly? Do anyone have a write up?

Here is a write up on a 1/2 ton but it is essentially the same:

You need to be careful knocking out the wheel studs so as not to damage them or just buy new ones.

You will need the special "hub" spindle nut socket to remove the retainers, while doing this it is a great time to clean, check or replace and repack your wheel bearings and seals.

Remember to follow the factory service manual with regards to re-torquing the spindle nuts - remember the specs in the above article are for a standard D44 not your Dana 60\61

 

I always thread a lug nut on the stud to protect the threads.

It is not a very good idea to compress the caliper piston like that. I have seen the back of the piston separate from the piston walls. Place something flat across the face of the piston and use a c-clamp or large pliers.

 

Thank you both for your fast reply. This looks aprox plain foreward.
My hub looks different than this one, I have a sort of wheel to engage the front axle, but maybe that doesn't matter.

Whats the size of the socket used om he retainer nut?

As I mentioned the procedure was written up on a 1/2 ton where as yours is a 3/4 ton so yours is going to look different.

As far as the special socket it isn't specifically a "size"...they have prongs on the socket to engauge in the retainer. Here are some examples:

Which one you need depends on which axle you have; your truck could have either a D44HD or a D60 dependin on the options.

 

The socket does not have a size designation like most sockets. It is a special socket that has four **** inside that fit in the four notches on the round nuts on the axle. The pictures show the nuts. This site shows the socket, I prefer the sixth one down because it is self centering.

The sockets are sold as 1/2 ton or3/4 ton at orielly auto part stores. 3/4 ton is bigger diameter. It's a lot like a spanner lock nut but theres no way to get a spanner in there

 

When I did mine, I had to use a little penetrating oil to get my wheel studs out. Like SEAL said, thread a lug nut on the stud as much as you can without having any threads come through... You do not want to mushroom out the threads on your studs. Use the same lug nut for all of the studs, that way if it gets ruined, you only have to buy one. Also, there are two different rotor options, one has a taller hub than the other. At least that was the case for my '85 1 ton.
