Lu,
Done a bit more research and Boeing apparently changed to Royco11MS in 1997 from Aeroshell 7
"The truck beam pivot pin and the brake rod should only be lubricated with Royco 11MS grease. Royco 11MS grease provides better lubricity than the current MIL–G–23827 grease (Aeroshell 7) at these locations.
Royco 11MS grease contains molybdenum disulfide which is desirable for highly loaded movable Joints."
The greasing inteval has also been reduced from 2A to 1A.
