New to Lexus. I have just purchased a friend's 2004 RX 330 AWD with 237,00 miles on it. (Original from USA) He hit a road construction site in the rain and the rear driveshaft fell out doing damage to the transfer case etc. After huge estimates to fix by the Toyota dealer in our area, I chose to take to a trusted mechanic and see it repaired more reasonably! No luck on a driveshaft from used so have ordered from Lexus Online: 1600 plus freight. and a used transfer case 710 plus freight. Any advise appreciated. Where to purchase parts etc. Thanks Car is loaded with Nav, DVD player with wireless headphones etc.
