To check #9, lie on your back and crawl under the car. You may want to wear gloves because the service brake cross shaft will be greasy from U-joint leakage. Grasp the shaft at either end and shake it up and down. If the bushings have not been replaced, you will hear and feel a strong metallic rattle as the shaft knocks against the inside of the bushing. The noise will be louder than you think it could possibly be. The solution is not to force grease into the bushing. The shaft must be removed and the bushings replaced.
I would bet close to 100% of the worn out, unrestored or poorly-restored Model A's I have worked on had this problem.
