Aqua The best way to pull/replace that oil is with a suction gun (pepboys) necked down with a small tube , there a very small amount of 90 wt oil (3 oz) in the bearing cavity and the "milk" suggest that the "mechanicl shaft seal is seeping. Seal leakage is often due to fishing line our weeds etc . The seals dont generally fail on thier own. Replace it and drive it again to see IMO, caution don't over fill it too much oil can cause the bearings to overheat ! Tom
Ps Check out our Modification kit for that drive if you haven't lately , uses all Berk style bolt ons (droops Place diverters etc) A/T internal parts ,17 4 race shaft ,HD Dominator bowl etc etc
