We picked up our 16 in Backus this spring. In climbing underneath I found the Lippert Axle sticker and see I have the easy (superlube) hubs. I found the Lippert axle owners manual on-line (Scamp provided none). The owners manual goes over major bearing and electric brake replacement items but never once mentions the super lube feature nor how to properly add the correct amount of grease. (I have a grease gun for other purposes but have never had to grease wheel bearings)
In reading other on-line searches for the answer I see where some people spin the raised wheel adding grease until its forced out the front cup and others add very little as routine maintenance to avoiding catastrophe and pushing extra into their electric brakes.
(The Lippert owners manual recommends "Lithium Complex" greases.)
(The Scamp owners manual says "Bearings should be lubricated every 5,000 miles....." AND "remove rubber cap ........... inside you will find a grease zerk.".) Not much help
I sent an email to Lippert but have not heard back.
So how much do you add? Sugestions most welcome.
