to take off the rear drum there is a 1"1/8 inch bolt on the rear
end. undo and straight towards you. if u pull side to side you may

to do and will cost around 95 bucks to replace the bearing and then
u gotta get the old one pushed out so just pull straight off. its a
30 mm bolt just to save sopme one the trouble of two trips to the

NOTE: this answer assumes you are working on a front wheel drive vehicle in regards to how to stabilize the vehicle prior to jacking.
1. Remove hub caps, or if hubs are held on by lug nuts, crack loose the lug nuts with the car on the ground.
2. Using a jack, lift up one side of the vehicle and place on a jack stand. Then raise the other side and again place on jack stand. Be sure not to lift the front tires off the ground as they are holding your care from rolling.
3. With the parking brake set, remove the lug nuts and pull off the rear tires.
4. Release the parking brake. Attempt to freely rotate the drums and slide them off. (this is not likely to be the case, but if they slide off luck you.) If they didn't just slide off, you can try pounding on them with a hammer to try to loosen them, but that is also not always effective. You may need to use 2 pry bars, or large screw drivers to attempt to pry them off. Some vehicles have holes in the backing plates that allow access to the star adjuster so you can crank the shoes in and release the pressure on the drum.
On some vehicles like the early 90's Toyota's you may notice that there are 2 threaded holes near the center of each drum. They appear to be an 8mm or so diameter bolt. These are the key to removing those type of vehicles drums. With 2 bolts in those holes you are able to alternate tightening them into the drum and they will bottom out against the hub and slowly they will push the drum free of the brake shoes.
5. Once you have the old drums off of the rear brake assemblies, you can clean the assemblies with a liberal application of "Brake Kleen" or a similar spray can type evaporative cleaner.
6. At this point you need to decide if you are just going to install the new drums, or if you need to replace the pads (cracked or worn), or the hardware / springs, and of course check the wheel cylinders for leakage.
7. If everything looks okay, then you will likely need to adjust the rear brake shoes in order to fit them into the thicker new brake drum. Turn the "Star Wheel Adjuster" in order to allow the rear shoes to come closer together. They should be adjusted to where the drum can slide over them into place, and if you spin the drum you should feel a very slide drag from the shoes.
8. With the new drums in place, go ahead and reinstall your
wheels and seat the lugs. Then drop the car back onto the ground
and torque the lugs to the manufacturers specs. Then reinstall your
hub caps and you're good to go.
BFH, squirt WD 40 on the hub and around the studs. Tap outward on the inner edge of drum while rotating it.
