When I bought the bike the original owner gave me a bottle of the 80/90 GL-5
so of course I used it!
Now to figure out "wheel slap"

Change out every 12,000 miles or once per riding season, regardless of miles.
Now, watch this get beat to hell on a public forum...
I have used BMWGear Oil 75/140. I no longer recommend it anywhere but in the transmission.
I have since returned to BMW hypoid gear oil 80/90 GL-5 in the final drive. 100,000 miles
GL-5 seems to be required
best wishes on your 01/02 they were the best build years
