I'd forget the manual that was written for a product over 30 years ago. Use the instructions from the manufacturer of the current product you purchased. They may use different materials for their seals, etc......
I have a 60 Pontiac with grease fittings everywhere. If I bought a replacement ball joint today and went by the cars manual I'd be hard pressed to grease it since they have no grease fittings anymore. They're factory lubricated for life, so they say.

"Kilgore Trout once wrote a short story which was a dialogue between two pieces of yeast. They were discussing the possible purposes of life as they ate sugar and suffocated in their own excrement. Because of their limited intelligence, they never came close to guessing that they were making champagne." - Kurt Vonnegut
