Why is wheel bearing repacking important for my boat trailer?

Wheel bearings support the trailer's weight and let the wheels turn smoothly. Repacking them with fresh marine-grade grease helps prevent overheating, corrosion and bearing failure, especially after the hubs have been dunked in salt water.

How do I know if my trailer wheel bearings need service?

Common signs include grinding noises, wobbling wheels, excessive heat at the hub, grease leaks, or vibration while towing. If you notice any of these, have the hub checked before you tow again.

What is included in a wheel bearing repack service?

We remove the hub, clean and inspect the bearings, races and spindle, repack the bearings with marine grease or replace them if worn, fit new seals, and set the nut to the axle maker's end-play spec. Then we spin the wheel to check that it turns freely without wobble.

When is hub replacement necessary instead of repacking?

Hub replacement is required if the hub shows scoring, corrosion, heat damage, or if the bearings spin inside the hub. Replacing the hub prevents repeated failures and unsafe towing.

How often should trailer wheel bearings be serviced?

We recommend once a year for trailers that go in salt water, or sooner if you hear grinding or a hub runs hot. For mileage, follow the axle maker's schedule.

Can worn bearings cause a trailer breakdown on the highway?

Yes. Failed bearings can seize, overheat, or cause wheel loss while towing. Regular repacking and hub inspection significantly reduce the risk of roadside breakdowns and accidents.

Do you inspect other trailer components during bearing service?

Yes, we also inspect seals, spindles, hubs, lug studs, and brake components when accessible. Any safety concerns are documented and discussed before further repairs.

Trailer Wheel Bearing Repack & Hub Replacement

Without regular boat trailer maintenance, a seized bearing can leave you stranded on the side of the freeway. We disassemble your hubs, inspect the spindles for damage, and hand-pack new bearings with high-temperature marine grease for safer towing.

About this service

Trailer Safety

Don't Lose a Wheel
on the Freeway.

Saltwater immersion followed by highway heat destroys trailer wheel bearings. We provide complete hub service, repacking, and trailer hub replacement, so your trailer is ready for the road to the ramp.

The Physics of Failure

When you tow, your hubs get hot. When you dunk them in cold water at the ramp, the air inside contracts, creating a vacuum that sucks saltwater past the seals. That water rusts the bearings.

Hand-Packed

Using a grease gun on a "Bearing Buddy" isn't enough—it often blows out the rear seal. We disassemble the hub and hand-pack the bearings to ensure grease penetrates the roller cage.

Hub Replacement

If your bearings have seized and spun, the hub surface is destroyed. In these cases, the boat trailer repair includes replacing the entire hub assembly with a new, galvanized marine-grade unit.

Service Protocol.

Dirty work done with precision.

Jack & Strip

We lift the trailer, remove the wheels, and strip the old hubs. We clean all old, contaminated grease from the spindle.

Inspect Spindle

Crucial step: We check the axle spindle for scoring, pitting, or cracks. If the spindle is damaged, new bearings will not last.

Pack & Seal

We pack the new tapered bearings with marine wheel-bearing grease, install new double-lip seals, and seat the races fully.

Torque & Spin

We tighten the castle nut to seat the bearing, back it off, then set the nut to the axle maker's end-play spec so the wheel spins freely without wobble.

Roll Smooth.

Preventive maintenance helps you avoid tow bills.

Common Questions

How often should I repack?

For saltwater use, we recommend an annual inspection and boat trailer bearing repack. At minimum, it should be done every 2 years or if you hear any grinding noises.

Can I just add grease?

Adding grease pushes out water, but it doesn't remove the sand or rust already inside. A full disassembly and cleaning is the only way to know your bearings are safe.
