Good time to check for rust on the lips of the drums .... gotta hate that on/off squeak sound
(This setup as on my car (1992 Dodge Colt 200 Hatch 1.5L)
Type 1 (1991-2 Colt Hatchback and sedan)
If you have the integral bearing hub/drum setup you will have to tighten the nut to a final torque of 108-145 ft/lbs while turning the drum to seat the bearing(s) properly. You will need a 30mm socket to get the nut on/off. You will also need a press to remove the races as "mykelmirage" noted previously.

Type 2 (1991-2 Colt Hatchback and sedan)
[2 options I've found]
This setup is a non-integral hub to drum assembly.
The drum comes off after you pull your wheel off. Your hub is bolted down separately.

(Option 1)cotter pin model
You will have to deal with a different torque specification of 14 ft/lbs, then rotate drum to seat bearing. Back off nut and retighten to 89 in/lbs and replace lock cap and cotter pin.

(Option 2)non-cotter pin model (see type 1 above for torque spec)
