So it's pretty straight forward, I could do it in an hour or two with no special tools (just a jack and basic sockets/wrenches/screwdrivers to get the rotor off or the axle out)?
And lugs are available at <fill-in-the-blank> parts stores, right?
I just replaced two on the rear without removing the axle. After the drum was off I just used a hammer on the old lugs to remove them. There was enough room to get the new ones in after oiling the holes to reduce friction. Then I attached nuts and used an impact wrench to press them into place. Took about 5 minutes. And I was prepared to remove the axle and take all day. How often does that happen?
