When should the front and rear differential oils be changed?
What is your question?
The vehicle is a 2012 Lexus RX450h with 35,000 miles.
According to the the Warranty and Service booklet an oil change should be done on the front and rear differentials. The technician states that this vehicle does not have differentials, yet the booklet lists the differential oil change as a task to be done on this vehicle. The technician thinks the booklet is incorrect and this oil change is a typo. Is the booklet wrong?
What makes this problem better or worse?

Hello, the rear differential on the all wheel drive vehicle should be inspected every 30,000 miles per the "normal" maintenance interval. For "severe duty", it should be checked every 30,000 miles, and replaced every 60,000 miles. No idea why the differential is citing something contrary to your owners guide and the shop manual.
