My 470 lives outside all year in the desert and I've got several hoses under the hood that are showing cracks. Going through the usual online parts suppliers I use for OEM Lexus/Toyota parts doesn't seem to be working for all these various hoses. I've been doing Google searches like crazy and just can not seem to find complete hose diagrams with names much less parts numbers. Anyone have a good source so I don't have to pay the dealer? Any help is greatly appreciated.

Mine is a baby with only 126K on it. My mom bought one new in '05 and put just over 422,000 miles on it with no engine issues other than normal maintenance parts and a new alternator. Now the interior is a different story. IMO the interior quality overall is really lacking for a Toyota and while garaging helps it doesn't stop the inevitable degradation.

The sunroof on my GX 470 has been noisy for awhile now but seems to be getting worse. I was on a slightly washboard road the other day and it was awful. Rattles like crazy. So bad that I'm afraid to really take it offroad. I tried to see if I could find screws or anything else that seemed loose and did snug a couple screws but it didn't do any good. Anyone else had this issue and know what the fix is? Parts numbers? Any help is appreciated.
