I have recently purchased a 2005 4wd EX. When I back into or out of a parking space and turn the wheel sharply, there is a vibration noise coming from the back. An amateur mechanic suggested it may be from the transfer case. I am taking it to AAMCO tomorow and don't want to be "taken for a ride." Any experience out there? Is this a common problem with a simple fix? Glad to hear about this club and thanks!
