The bearing will "roar" when they go bad. We had one in a 73 Dodge that got water in it and basically rusted out. The bearing should spin freely and cleanly as a front wheel bearing. They are lubed with grease and not the gear lube in the rear, so both the inner and outer seals must be good to keep the bearing sealed. On an 8-3/4 the spec I have for 68 model year is 0.013"-0.023" end play which is adjusted by the spanner on the passenger side of the rear and locked by a clip mounted to one of the backing plate studs.

If you have never done it before you are in for a treat. Multiply the time allocated by 4 and you might be close. It is a real PITA. I actually like using a Dremel with the smaller reinforced cutoff wheels as it gets closer to the "cheek" of the axle when cutting the race and splits easier. It is hell on a Dremel though...
If this is a street car you might want to get some opinions on using the "green" bearings. They aren't meant for cornering so you might be repeating this process. It depends on how much you drive it (I wouldn't use them on a street only car).

the oe tapered ones do get loose in the race. If yours NEED replacement I would get some new tapered Timkens rather than the greens

In my car it sounded like I was driving over the steel grating of a draw bridge- or rumble strips. Very attention demanding growl.
Keep old mopars alive.
