Re: Closed knuckle D70

The closed knuckles are designed to be filled with either grease or 140W oil to lube both the u-joint (remove the u-joint's seals) and the knuckle pivot bearings. There should not be any mud in the closed knuckle. With good seals, it would be better for mud than an open knuckle.
