Afternoon Scoobisteve That leakage looks awful high to be all from a final drive leak. Make sure that you don't have an engine or transmission leak that is allowing oil to blow back on the final drive. Otherwise clean the drive up squeaky clean then keep an eye on it after every ride. Any signs of oil dripping on the rear wheel rim after a ride? How much gear oil did you put in the drive? Link to comment
Scoobisteve Posted August 8, 2023 Author Share Posted August 8, 2023 it didn't take much...I took off the tire and changed it like like the manual says...just lowered the drive to drain, then put it back together and filled it up even with the hole...didn't notice any oil behind the boot when I did so...

I think there's a specific amount that goes in, not to the bottom of the hole as a measurement,......I could be wrong. Too much could cause too much pressure,.....I think Link to comment

Morning Scoobisteve You probably put too much gear oil in. That (early) 2005 final drive was designed around a higher oil fill but later BMW came out with a service bulletin to reduce the fill amount to 180cc. So you need to fill by a specific volume not to the bottom of the hole. (bottom of hole will over-fill it). Drain it overnight (drain hole straight down) then add exactly 180 cc of gear oil.
