Does the timing chain on a 1989 Toyota Pickup 2WD ever need to be replaced?
Yes, the timing chain can and does eventually develop wear/fatigue after so many years and miles. Other components of the timing system (such as the tensioner and guides) also wear out (and in fact are more likely to wear out sooner than the timing chain itself). The OE timing guides are made of plastic, so they tend to wear out relatively quickly compared to the metal components. There also are gears as part of the system. If the truck has over 200,000 miles, and the timing components have never been replaced, I would recommend buying a timing kit which comes with all the necessary parts (chain, guides, tensioner, gears, seal, gaskets). You can get a good quality kit for about $100.
