Why does the ford explorer make a rattling noise when accelerating?

In the 2013 Ford Explorer, if You hear a rattling noise when accelerating that may mean Your timing chain is worn or going out. A timing chain synC-HRonizes the rotation of the crankshaft and camshaft(s) ensuring proper timing and allows the engine's valves to open and close during each cylinder's firing. The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well.The cost of replacing a timing belt or a timing chain is generally anywhere from $300 to $500. If You head to AutoZone right now You can find timing chains that cost You anywhere from $30 to $100 or more. There are also timing sets which include the gears You need that can cost anywhere from $20 to $250.
