What is the Recommended Maintenance Schedule on a Trailer

Question:

After how many miles is it necessary to grease wheel bearings? I installed electric brakes which included the hub/bearing assembly with the axle-end grease fitting about a year ago and have pulled the trailer about 6500 miles.since. Thanks!

The recommended schedule to grease your wheel bearings is every 12 months or 12,000 miles, whichever comes first.

You can use the red grease # L11390 for trailer wheel bearings if you wanted. You can also use wheel bearing grease # L11465 which is designed for use on trailer running gear, including wheel bearings. It also has a slightly higher temperature rating, 520 degrees, compared to 510 degrees for the red grease.

When adding new grease you will need to make sure that the new grease is compatible with the old grease or remove the old grease completely. Incompatible greases can break each other down. I have included a link to the right to our help article on greases that should help. You will need to inspect the bearings and races before repacking them and replace the grease seals since they will most likely be destroyed in the process of removing them.

I have included a couple FAQ's and video for you too.
