Your trailer works hard for you—hauling heavy loads, traveling long distances, and braving Alaska's rough roads. But like any hardworking piece of equipment, it needs regular care to keep running smoothly. One of the most important (and often overlooked) maintenance tasks? Repacking your wheel bearings.
So, what exactly is a bearing repack? It's the process of removing the wheel assembly, cleaning the bearings to get rid of old grease and debris, inspecting for wear or damage, and then applying fresh grease before everything is reassembled. It requires the right tools and know-how, which is why most trailer owners leave it to trained technicians, like our service team here at Alaska Trailer.
If your bearings are already making noise or showing damage, don't wait. Bring your trailer in right away before the problem gets worse. Here's why bearing repacks are so important and how to know when it's time.
Why Do Trailer Bearings Need Repacking?
Wheel bearings let your wheels spin freely with minimal friction. Without proper lubrication, they can overheat, wear down, or even fail—leaving you stranded. Over time, bearing grease breaks down and can get contaminated, losing its ability to protect your bearings. Water, especially from driving through rain or snow, can also seep into the hub, causing rust and accelerating damage.
How Often Should Bearings Be Repacked?
As a general rule, trailer wheel bearings should be repacked with fresh grease at least once every 12 months or every 12,000 miles, whichever comes first. If you use your trailer frequently, haul heavy loads, or drive in wet or dusty conditions, you may need service more often.
Signs Your Bearings Need Attention
Not sure if your bearings are due for service? Look (and listen) for these signs:
- A whining or grinding noise from the trailer wheels while driving
- The hub feels hot to the touch after a trip
- Rough or uneven wheel rotation
If you notice any of these, schedule maintenance right away before the bearings seize up completely.
