...Transfer Case Oil is located.Thanks There are 2 things I would like to learn to do it myself. 1- Differential oil change. 2- Transfer case oil change. I, however, have never done it before. If there are tips of how to do it yourself, that would be very helpful. I really appreciate your help. I live very far from the Lexus dealer, therefore learn how to do it would save a lot of time. Thank you very much.
