Default differential fluid change

80k mile son 2010 RX350 - dealer said i should change differential fluid. The invoice at the end said "customer requested fluid change" - inaccurate statement, so i want to know - when do i need to change that fluid?

Check your manual it will tell you. Believe mine says 100k initial change for regular interval 50k initial change for severe duty. I did mine at 70k when I bought it. Really easy to do, just 2 plugs and no need to jack it up, just get under the rear and do it. Check the 3rd Gen forums. This is the 2nd Gen. Similar drive train, but yours is different.

BlackLexRX is spot on, my pro tip is to always take off the fill plug first before draining the fluid just in case you for some reason can't get it off or strip it.
