Starters are a momentary use item, life depends on how much they are used. A person who does alot of stop and go driving is going to need a starter sooner than someone who drives the freeway more often. 70K is not unusually short for replacement. If the battery had 1 weak cell for a while and was not supplying enough voltage to the starter for it to turn over efficiently it could have contributed to the problem.
