Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.

In this regard, can you over grease bearings?

A common and costly problem in grease application comes from over-greasing bearings. Over-greasing bearings can lead to abnormally high operating temperatures, damaged seals, and in some cases, such as electric motors, energy complications and failure.

One may also ask, how often grease RV bearings? Time Frame. Wheel bearing maintenance frequency depends on the trailer type, wheel size, and average load weight. Some manufacturers recommend inspecting and greasing an RV's wheel bearings once every season, or at least every 10,000 miles. But boat trailers with small wheels require re-packing every 2,000 miles.

Is Lithium Grease OK for wheel bearings?

Typically lithium-based, it's usually not water-resistant or waterproof, nor is it rated for use in bearing applications. While it would work in a pinch for boat-trailer bearings, it's not the best grease for this application. White lithium grease is a popular multi-purpose grease.

How does the rear wheel bearing get lubricated?

Re: Rear wheel bearing lubrication? The oil seal keeps oil from leaking out of the hub. The seal is between the hub and the axle housing so keeps oil from leaking out behind the hub. There is plenty of room between the axle housing and the half shaft for oil to get through to the bearing.
