How do I. Change the front wheel bearings on my 1984 rx 7

The 84 RX7 has a hub/ rotor assembly. Pull the front wheels, take off the calipers, remove the grease cap from the rotor, take out the cotter pin, take off the nut, pull the hub/rotor off. It may be difficult but pry the old bearings out, there is an outer and an inner, the inner has a seal on it. Clean out the space where there old bearings were, and press in the new ones, this will also be difficult. Make sure to use a method that puts even pressure on the bearings; I like to use a screwdriver that will fit through the hole in the bearing but the handel will catch, then I tap on the back of the screwdriver until the bearing seats in place. Be sure to pack the bearings with plenty of grease, you will make a mess. Then installation is just reverse of removal. When you put the hub nut back on, tighten it down, then back it off just a tiny bit so that it lets the bearing spin but doesn't have any play. As always, double check all of your lug nuts when your put your wheels back on. Hope this helps!
