It's debatable when the a chain and gears need to be replaced on these I4 and I6's. There are several thing to consider. If you have a 4 or 6 cylinder (the 6 tends to be stronger longer), if you off road in it (at all) and also how many "hard" miles you have on it. If you have 250,000 miles on it, but only drive it to the store and back at 35 mph, that set will probably last forever. If you have over-sized tires and have been off-roading for the same 250,000 Miles, you probably should have changed them 150,000 miles ago... But to answer your question, changing them at 150,000 miles seems to be pretty routine. My 2.5L has 170,000 on it and it needs one bad, and plan to change my timing set next week.
ALSO!!! Get an Pan gasket too, because you have to remove the pan to get to the chain tensioner bolts.
Gear set, gasket sets and oil your looking at about $200 in parts; and for amateurs like me, a nice uninterrupted 18hours to do it; correctly.
BTW: Look on Ebay for the Gear set, the Zone had the best deals on gasket sets, Advanced have the best oil w/ Filter deals, and the best part... they all take PayPal! Hope this helps.
