1998 LS400 Diff Oil

[Razor61]

Hi, has anyone changed the diff oil on their LS400? If you have then what diff oil did you use or recommend?
Any advice would be appreciated thanks.

Any gear oil that is GL5 and SAE 75W90 or SAE 80W90 will do.

Every 27,000 miles I think is the service schedule. I used Redline synthetic last time and it's due again soon.

Don't forget to make sure the fill plug can be undone before draining the diff.!
