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..
Keeping this in consideration, can you over grease a bearing?
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.
Furthermore, how often should you grease equipment? The manuals usually say grease every 50 hours, though I usually do every 25 hours because grease is cheap insurance against pin wear. Also, putting in a little bit of grease in every fitting frequently is better than putting in a ton all at once and then leaving it for ages.
Similarly one may ask, how often should you grease travel trailer wheel bearings?
Generally speaking, you need to inspect and grease your travel trailer wheel bearings once a year or every 10,000 miles, whichever comes first.
