If only life was so simple... According to Thule, all their trailer htich will not work with LX 470, 2004. Tire is in the way for the pin to fit and they do not support/recoomand using extenders. I also talked to Lexus, there is no other option so it seems. *sigh*
Hello,
If you have the hitch thats integrated in the bumper, then you're going to have to cut the Thule down until it does fit. If its the attatchment type of hitch and its "under" the bumper, then it should fit just fine. The problem is that the hitches integrated into the bumpers are to close to the spare tire causing anything longer than the hitch, to hit the spare. I had this same problem and had to actually cut down the Thule a bit so it wouldnt hit the spare tire anymore. I've had this for several years now with endless amounts of bikes hitched up, and its a 4 bike rack, so it does tend to get heavier than most, and i havent had any problems at all. Good luck!
