Trailer bearing and seal maintenance

Checking your trailer bearings isn't a quick process, but it's something worth setting an afternoon aside for every 10,000kms or 12 months, but what exactly are you looking for?

After removing the wheel and hub, remove and clean your bearings so you can have a proper look at them. If you notice any visual damage to the rollers, roller cage, bearing or bearing race or any discolouration or evidence of excessive heat and friction, it's time to fit some replacement trailer bearings. Make sure to use quality grease when reassembling the bearing assembly. The more care you take now, the less likely you'll need to repair or replace on the side of the road, should something go wrong.

When taking the assembly apart, it is important not to overlook the seals. If they are damaged, dry, brittle or cracked in any way then they must be replaced to ensure the assembly stays lubricated. It's worth taking into consideration that all of these components are relatively inexpensive and can be replaced before the due date to prevent any future damage or breakdowns.

If you tow regularly or subject your trailer to extreme conditions, bearing protectors are a great idea to maximise the service life of your bearings and seals. These handy little accessories protect your bearings and seals from dust, dirt and water which can break down bearing grease and damage seals. They also add a greaseable point for quick service without dismantling the entire assembly.
