So I bring it to the dealership that I purchased from, the service technicians hear the clanking noise. Goes in for warranty, tech tears the rear and apart finds nothing wrong and puts it back together . now says I might have to pay for the diagnosis. Why would I have to pay for diagnosis for something they can't find that they definitely heard? Anybody else have this issue with clunking in their rear and while and 4 wheel drive ? So frustrated. Been without it for weeks so far.
