The hubs are where the fun's at... Mine were easy but i've only ever heard of them being Whoures on other trucks.
Jackstand the truck.
Remove the tires.
Remove the Brake calipers and wire up (wire them or they WILL find a way to fall)
Remove the 4 bolts on the inner side of the hub. If you are lucky... your soul is righteous and you are on the path of salvation, your hubs will be loose enough to remove without excessive force.
If not, para military force is in order.
I left the axle attchatched through my hub and slid the hub, rotor and axle out of each side as one unit... 4 hands are helpful with this. Don't let the axle get dirty.
Once you have the hubs, rotors and axles out, pop the tie rod and then remove the nuts on the balljoints. Leave them loose on the ballstuds to keep the knuckle from hitting the ground.
I took a large pry bar (30 lb, 6 ft long) and loaded the knuckle,pressing down, while hitting the inner knuckles with a 5lb sledge... both sides popped after about 5 solid hits.
I got the old joints out by hand but had to have the new ones pressed in. You have that taken care of, if your press is large enough.
Installed the new knuckles, torqued the shiznit out of them.
As said before. . ANITSIEZE EVERYTHING... If it looks suspicious. . goop it with antisieze. .
Keep it away from the axle though. Put Goop around the circular flange on the hub where it engages into the knuckle.
Slide in hub/rotor/axle assembley
Goop 4 bolts
Reattatch tie rods (made accessing the 4 bolts easier without Tie rod connected)
Replace brake caliper. .
tires... jack stands... drive it. .
I think I was vaguely accurate.
Hope this helps
On Edit: I forgot this. . It will help on installing the Passenger side axle if you remove the CAD actuator to make sure the collar is on the center axle and the two axles engage correctly into one another. My passenger side is still leaking because I killed the seal.
