What is bearing repacking?
Repacking a bearing is the process of removing the parts of the wheel to access, clean and add grease to the bearings. Over time the trailer bearings will take a large amount of abuse and wear, although they are designed to last for a long time, they will wear out prematurely if they are not routinely taken care of.
What is hub bearing?
A wheel bearing is a set of steel balls held together in a metal ring, called a race. At the center of your wheels, there is a hollow piece of metal, called a hub. The wheel bearings fit tightly inside this hub, and ride on a metal axle shaft, helping reduce friction when the wheel spins.
What is a front wheel bearing?
A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction.
What is a serviceable bearing?
If a sealed bearing assembly is noisy or feels rough when the wheel is spun by hand, it needs to be replaced. If the bearings are the serviceable kind, they need to be removed, disassembled, cleaned and inspected. If the rollers, balls or races are worn, pitted, cracked or show any damage, replacement is required.
Should I repack or replace wheel bearings?
To avoid a wheel bearing failure, you should regularly repack your wheel bearings. If you have a large RV and travel regularly, you should do this every year or 10,000 miles. If you’re not taking your RV on extended trips and it’s smaller, you should do it every year or 2,000 miles.
Is hub bearing same as wheel bearing?
A major difference between the two is how they are assembled. Wheel bearings can be taken apart, lubricated and reassembled to be used again. Hub bearings are pre-packed at the manufacturer’s factory and are sold and installed as a complete unit. These cannot be taken apart for re-lubrication, but must be replaced.
How often should wheel bearings be replaced?
about 85,000 to 100,000 miles
Most serviceable wheel bearings need maintenance every 25,000 to 30,000 miles, or during every brake service. But, the average life of a sealed wheel bearing and hub assembly is about 85,000 to 100,000 miles, without the opportunity for a technician to repack the bearings.
How do you know your hub bearing is bad?

- Squealing, Growling.
- Clicking Sound.
- Wheel Wobble.

Did all wheel bearings used to be serviceable?
All wheel bearings used to be the serviceable type, requiring periodic maintenance every 24,000–30,000 miles (38,624–48,280 km), consisting of disassembly, cleaning, inspecting, reassembly, and adjusting.
What are sealed wheel bearings?
The bearings are packed with heavy grease to lubricate and protect them. A seal keeps the grease in and water and dirt out. It’s when the seal starts to leak that problems begin. The grease can become contaminated; causing the wheel bearings to overheat and ultimately fail.
