The front hub assembly includes sealed bearings with no grease fittings.
There's no way to grease them.
The USA SKF (OEM) hub kit BR90056K includes the nut and a protective cap
The EU SKF (OEM) hub kit VKBA 1435 includes only the nut.
The nut is a keeper nut, not requiring a cotter pin

I had poor gas mileage with my 1995 850: 15-16 mpg city driving.
The similar sealed OEM hubs had 220,000 miles on them and were not making noise.
I replaced with cheap Chinese hubs that were worse than the old OEM Hubs
and in less than 5K miles, they started to grind. Then I replaced the front hubs
with German FAG hubs. The city driving mileage went up to 23-24 mpg.
I couldn't find German FAG hubs for the 940, and FAG (Schaeffler) is out of production for many 940 parts in their catalog.
Good luck, Bill
