When you had the drums off, did you inspect the shoes for excessive wear? And How do the drums look? Are they grooved? Can you be more specific about the loud noise. Does it sound like a grinding noise, or a screeching or pulsating noise. Is it lower pitch or high pitch?

Are the shoes adjusted up close to the drums?

either the brake wheel cylinder froze or stuck under pressure, or the shoe pins or retainer spring broke, the adjuster fell down and wedged, and possible the wheel bearing seized or welded, which i don't suspect the bearing its last on the list

Brake Drums-They seem to be fastened with a nut and have bearings that need to be regreased based on the diagram found for replacing the shoes. Removal & Installation To Remove:

If you have rear drum brakes, a brake shoe may have separated from the metal brake shoe lining and is "tilting" in and out, making the noise when you apply the brakes. It is very important to remove the drum and inspect the brakes because if this is what happened the wheel could
"lock" unexpectedly and cause you to lose control of the vehicle.

Step 1. Remove the the brake drum from the vehicle. Step 2. Once you have the drum removed, it is a good idea to clean the area of dust with compressed air or brake wash spray. Step 3. Disconnect the Springs, removing the outer one first using the brake spring removal tool. Step 4. Remove the two springs from the brake shoes. Step 5. Lift up on the Auto-adjuster and disconnect the adjuster cable. Step 6. Remove the Auto Adjuster Cable From the upper retainer and remove. Step 7. Remove the two Spring Loaded Brake Shoe Retainers. Step 8. Remove the Auto Adjuster Arm by sliding it forward and pulling outward. Remove the Spring and arm as one piece. Step 9. Pull the shoes outward and forward from around the drive axle assembly.
Step 10. Allow the shoes to colapse together so you can now remove the lower spring and adjuster with ease. Step 11. You are now left with one shoe still attached to the Park Brake arm assembly by one lock ring.. Step 12. Use a flat screwdriver and twist to open the ring. Then pry up on one end and this will allow it to release and be removed. Step 13. Use brake wash and clean the all surfaces. Step 14. It is important to lubricate the 6 points that the shoes slide on to prevent any noise. Non-drying silicon brake lubricant works well for this. Step 165 Insert park brake arm pin in New brake shoe and install lock ring. Step 16. Install the brake adjuster and lower sping. Pull apart and slide the assembly over the drive axle. Step 17. Install Spring Loaded Retainers to hold shoes in place so you can install the adjuster arm/spring and adjuster cable. Step 18. Install the Brake Shoe Springs.

It is best to assemble the shoes and springs and only then fit first the one shoeto the backing plate and then the other. Don't forget to fit the handbrake cable before assembly

Do one side at a time and use the other side as a diagram They not hard to do

drum brakes or disc brakes ? if drum brakes. yes but first remove the drums to be sure there is enough shoe left to adjust and to be sure there is no dirt or broken springs back there. if disc brakes no adjustment.
