Chevy AWD- lifetime, clearance and reliablity?
Looking at a 2006 Chevy Express HD1500 AWD Van here, but I don't know anything about the Chevy AWD systems. Main question is how long are they expected to last? I can find plenty about the 5.3L engine, but nothing about the lifetime of the AWD- that's either good or bad.
Second, what is real-world clearance and capability? I'm of course used to massive tires and transfer cases, but my wife's Volvo is extremely capable. In the Chevy van, what can one really expect to make it through?
