I believe the recommended interval is 15k miles.
My opinion. 1st is right when you buy it if used. 7-8k if new. For used, go to start from new schedule, new 2nd one after another 10-15k. After that you can let it go longer. Another 30k is fine, oil will still be clean. Each change should have significantly less metal shavings on the magnet. After the 3rd there should be next to nothing on the magnet. Same goes for the tranny.
If you have a clutch style LSD, cut everything in half.
