I have been looking for gx470 and 4runners for the last 6 months now, today i think the found one! 2008 4runner sport 4x4 v8 with 56k miles, clear car fax and their asking $18500. I think its pretty good deal considering the miles. I took it for a 1hr test drive and i did notice one problem, when driving in town i felt and heard the infamous rear end clunk once. Should i be worried or is it worth getting? Anything different the 4x4 system's in 2008? thanks for the help
