How Often to Repack Trailer Wheel Bearings?

IMO the first repack should be done within two years. Once you are certain the pack was done properly I would go at least 5 years or 30,000 miles. Just did mine at 10 years when installing disk brakes... all was fine.

I'll have to agree with this strategy. IMO every year is just silly, and either mostly wasted labor and/or money.

Unless you immerse them in water, pull the cap once a year. Leave it alone if the grease looks reasonably fresh.

My DW says I own too many trailers...more than 10. In the last 10 years I can only remember doing one...maybe because it was last month and only on one side of a boat trailer. I do remove the caps and it t grease has hardened I fill the cap with 90 weight gear oil and put it back on quickly. If the trailer is to heavy to wiggle the tire I will jack it up so I can check the bearing adjustments.

On the subject of tires...I only buy used LT takeoffs (5-7 tread left and less than 3 years old) for my smaller trailers.

PS: I've only been doing these things for only 40+ years so time will tell if it works.:B

How often do yOu repack your car bearings

The shop I use said it is more of a function of use. Contrary to what you might think he said that they should be re-packed if the RV has been sitting a long time. He didn't define long time....

I do my own. Some years we only do local trips. I always do them during the years we have a big trip planned.

I keep a spare set of bearings and seals in my RV toolbox....
