got a replacement for my '00 diff with the "death whine" what should I use for gear lube? how long before I can run LE607

any 80w90 or 75w90 hypoid gear fluid should be fine. the manual recommends straight 90 but that depends on the climate at your location.

i'd just stick with mobil 1 75w90. readily available and receives nothing but good reviews.

600 miles should be good enough for almost any part but personally i'd wait at least till 1000 miles before dropping the clutch,etc...

thanks for the info. have you seen the test info on LE 607 or amsoil series 2000 gear oil? why do you like mobile gear? now I do use mobil 1 in both my toyotas so please dont think I slamming you. just curious.

Mobil 1 has a history of "working" in this car, backed up by fluid analysis. LE is also building up a history but to date, have not been backed up with reported analysis out of this car. My philosoply is to go with what has been proven till you find something else that's just as good or better. Trying new stuff based on "what you hear" is a choice that only you can make since it will be you who will have to buy another part if the results don't pan out.
