Overheating wheel bearings are one of the most serious trailer issues we see — and one of the most ignored. Many customers only realise something is wrong once damage has already been done.
Bearings usually overheat due to old grease breaking down, water entering the hub, or incorrect installation during previous repairs. Boat trailers are especially vulnerable, but any trailer that hasn’t been serviced regularly is at risk.
The warning signs are clear if you know what to look for. If a hub is too hot to touch after towing, that’s not normal. Burning smells, vibration, or rumbling noises are also red flags. We’ve seen trailers lose wheels on Tasmanian highways because these signs were ignored.
Once bearings start overheating, continuing to tow can cause serious damage. Axles, hubs, and even wheels can be destroyed, turning a manageable repair into a major failure. This is why we always advise customers to stop towing immediately if they suspect bearing issues.
What people often get wrong is assuming bearings will “cool down” or that a short trip will be fine. Bearings don’t self-correct — they fail progressively and often suddenly.
We inspect and replace bearings in-house and carry common bearing sizes and seals in stock. During business hours, we can usually assess the problem the same day and advise whether it can be repaired immediately or needs further work.
If you’re unsure, don’t risk it. A quick inspection can prevent a dangerous and expensive breakdown.
