Location: Milwaukee, WI | Don't add grease until the round plate with the grease-fitting has moved noticeably inward toward the bearing.
The correct amount of grease has the b-buddy spring compressed about 1/2 of its travel distance.
I usually trailer about 2000 miles/year and I only add grease once per year. My gross trailered weight is about 2100 lbs. I use the black, molybdenum-additive grease, made for farm implements & construction equipment. It has a high tolerance to water.
When its all working correctly (b-buddy & inner grease seal) there is nowhere for the grease to go. It does not get burned-up. It simply becomes liquidy and flows around the moving parts. The inner seals should keep the grease from leaking out.
Check your hubs after trailering a dozen or so miles at highway speed. Use your fingers to try & feel if they are heating up. If they feel warm, and you can leave your fingers on them for like 15 seconds without getting burned, they are doing fine. I usually check mine when we stop for gas. |
