Packing bearings is going to involve filling them with grease to ensure proper lubrication.

Follow these steps to properly pack bearings in a hub assembly:

• Clean the bearings and the hub thoroughly.
• Apply a suitable high-quality bearing grease.
• Place a generous amount of grease in the palm of your hand.
• Press the bearing firmly into the grease while rotating it.
• Continue rotating and pushing the grease into the bearing until it emerges from the other side.

Signs of a worn or damaged trailer bearing:

• Excessive noise, such as grinding or humming
• Wheel play or wobbling
• Uneven tire wear
• Vibration
• Overheating

If you notice any of these symptoms, it is important to inspect and service the bearings as soon as possible.

To determine the correct size and type of trailer bearing kit, you need to know the specifications of your trailer's axle and hub assembly. This includes the bearing part numbers, axle weight capacity and hub dimensions. Refer to the trailer manufacturer's documentation or consult with a professional, if you are not sure.

Follow these tips to extend the lifespan of trailer bearings:

• Perform regular inspections and maintenance
• Keep bearings clean and free of contaminants
• Avoid overloading the application beyond its capacity
• Use the appropriate lubricant and follow proper lubrication procedures
• Monitor operating conditions and address any issues promptly

Trailer bearings should be inspected and serviced, at least, once a year or every 12,000 miles, whichever comes first. However, if you frequently tow your trailer or operate in harsh conditions, more frequent inspections and maintenance may be necessary.
