New Owner- 2009 Lexus GX470 one owner with 39,000 original miles (documented dealer service completed every 5,000 miles - car lived in Newport California) . I took the car to Lexus and had it thoroughly checked out. They gave me a list of items to do and some to watch and wait. The to do list includes new CV boots (EARLY leaks on both sides) and rack and pinion unit (small leak on both sides). Both of these considerations we disclosed before I purchased and I am good to have them done. The surprise was that they did NOT recommend the TB/WP. They appreciated my research highlighting that TIME and peace of mind was the trigger for me (and not the 39,0000 original miles). They will do it if I ask them to, but they think I am a bit over zealous and it would be a waste (quoting that car and other components just look too new including drive belt as a surrogate marker) - recommendation was to wait till at least 60,000 mile or a couple of more years. Any thoughts?
