How to Deal with Squeaky Car Door Hinges?

[SanLiam]

Car door squeaking noises mainly originate from the door hinges and limiters. The solution is as follows: 1. Use a cloth or tissue to wipe away dust from these areas; 2. Open the engine hood and pull out the oil dipstick, then use a cotton swab to absorb a certain amount of oil from the dipstick; 3. If one dip is not enough, reinsert the dipstick and pull it out again to absorb more oil; 4. If engine oil is unavailable, use cooking oil or grease as a substitute; 5. Apply the oiled cotton swab repeatedly to the marked areas (red circles) on the door hinges and limiters; 6. Open and close the door repeatedly while reapplying oil until the squeaking noise disappears. Hinges, also known as butt hinges, are mechanical devices used to connect two solids and allow relative rotation between them.
