This post covers the steps, tools and details of changing the transfer box oil in a Land Rover LR3. Changing the transfer case oil is very easy. The transfer box uses Land Rover part #IYK500010. The transfer case oil capacity is 1.5 US Quarts. I buy the oil from Land Rover Merriam Parts at $30.91 a quart (June 2018).

Special note: If you wish to replace the copper washers, you must use the correct washer, Land Rover part # IYF500030. Generic, off the shelf copper washers are too big in diameter and will not fit.
