What Causes the Ticking Sound in the Car?

[MacColton]

Here are the reasons and solutions for the ticking sound from the wheels: 1. Small stones in the tires: If there are only a few stones, you can use a screwdriver to remove them from the tread grooves yourself. If there are many stones, during maintenance at a 4S shop or repair shop, ask the mechanic to deflate the tires and tap them to dislodge the small stones stuck in the tread grooves. For slightly larger stones wedged inside, gently pry them out with a screwdriver. 2. Engine noise: Replace the engine mounts to prevent engine vibrations from transferring to the car body, reducing vibrations and eliminating the noise. 3. Severe wear: If the "ticking" sound from the valves persists even when the engine is warm, it is necessary to open the engine valve cover to inspect the wear on the camshaft and pushrods. If obvious wear marks or damage are found, replacement or repair work is required.
