What is the reason behind the rattling sound produced by the Ford Explorer when it speeds up?

In the 2013 Ford Explorer, if you notice a rattling sound when you step on the gas pedal, it could indicate that your timing chain is worn out or failing. The timing chain in your vehicle is responsible for coordinating the movements of the crankshaft and camshaft(s), ensuring they operate in sync and allowing the engine's valves to open and close at the right times during each cylinder's combustion cycle. It is essential that the timing chain is well-lubricated by the engine oil to function properly, highlighting the importance of regular oil maintenance. The cost of replacing a timing belt or timing chain typically ranges from $300 to $500. If you visit an auto parts store like AutoZone, you can find timing chains priced between $30 and $100 or more. Additionally, there are timing sets available that include the necessary gears, which can cost anywhere from $20 to $250.
