★ Top Answer
The 2005 Toyota 4Runner with a 4.0-liter engine comes with a timing chain, whereas models with a 4.7-liter V8 engine have a timing belt. The function of a timing chain is to synchronize the camshaft and crankshaft by using links. However, friction may cause the chain to shed small fragments into the oil drain pan, leading to a rattling noise. In more severe instances, the chain may break and necessitate a replacement, with the average cost ranging from $1,040 to $1,350 for the 4Runner, including labor costs of about $950 to $1,200. On the other hand, a timing belt in the 4Runner, which is made of rubber with teeth that interact with other parts' gears, requires periodic replacements unlike a chain. The average cost for replacing a timing belt in the 4Runner is approximately $530 to $760, with labor making up around $280 to $360 of that total.
