How often should you repack the wheel bearings on a travel trailer?

It is recommended that the wheel bearings be inspected and then greased at least once in every season. Another recommendation is one greasing after every 10,000 miles covered. However, the smaller trailers that have smaller wheels will need repacking after 2,000 miles.

How often should you repack caravan wheel bearings?

Wheel bearings get a workout on any caravan and should be checked and re-greased every 10'000km or 12 months. Don't forget you'll need a new split-pin and a bearing seal for each axle, and be prepared to replace the inner and outer bearings if they are pitted or worn.

What happens if a wheel bearing fails?

It may become more pronounced during turns as the car's weight shifts and a different load is placed on the wheel.

Can you put too much grease in a bearing?

Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures. This can result in accelerated wear of the rolling elements and then component failure.

How can I tell which wheel bearing is bad?

You can test this by gently swaying your car while driving slowly. If the noise lessens when you sway right, then the damaged bearing is likely on a left wheel bearing. If it lessens when you sway left, a right wheel bearing is likely broken.
