8 3/4 hard to rotate wheels

One side should have an adjuster to set bearing pre-load. Usually I believe this adjuster is on the passenger side but it is not exclusively designated to that side, especially if someone has gotten their hands on it and "modified" it in some way. I would pull axles and grease the bearings, install them back in and tighten adjuster so there is no end play.....some say to leave a couple thousands of end play....I figure with a freshly packed bearing, that will be a couple of thou when you get rolling.

I have also run across with new drums hitting the backing plate when wheel is torqued. Grind off a bit and try again.

thas all I got.
