That question was asked at the rally when Lippert did its vendor presentation. They passed out several different manuals. The recommended greases are:
- Mobil Oil's Mobilgrease HP
- Exxon/Standard's Ronex MP
- Kendall's Kendall L-427
- Ashland's Valvoline Val-plex EP Grease
- Pennzoil's Premium Wheel Bearing Grease 707L
Basically look for the following specs:
- Thickener type - Lithium Complex
- Dropping point - 230 degrees C (446 degrees Farenheit) minimum
- Consistency - NLGI No 2
- Additives - EP, Corrosion & Oxidation Inhibitors
- Base Oil - Solvent Refined Petroleum Oil
- Base Oil Viscosity - @40 degrees C (104 degrees F) 150cSt(695 SUS) Min.
- Viscosity Index - 80 Minimum
- Pour point - -10 degrees C (14 F) Minimum
I'm an accountant, not an engineer, so I don't really know too much about what I typed - just copying from the spec sheet.
Make sure the bearing is clean, but don't leave it dry for very long as it oxidizes rapidly.
- Tighten spindle nut to approximately 50 ft-lbs and rotate hub.
- Stop hub, back off nut so you can tighten by hand.
- If spindle hole aligns with slot in nut, install cotter pin or bend over locking tab of tang washer.
- If it doesn't align, back nut off until it does, never go in the tighten direction.
