There’s no such thing as too much grease for bearings! It should be a tight fit to where you would have to use a tool or block of wood to get the grease cap in place. If one side is in further in the hub than the other side of the same cap then eventually it will work itself free.

Is it easy to replace a wheel bearing at home? Replacing a wheel bearing that comes as an assembly with the hub and bolts to the spindle or steering knuckle is not very difficult if you have proper skills, tools and the manual. Of course, the large axle nut is very tight and can be difficult to remove.

The axle manufacturers recommend that you repack your trailer bearings once annually or every 12,000 km….How can you tell when your bearings start to fail?

1. SOUND. You will hear a screeching, grinding or roaring sound coming from your tires in motion.
2. TIRE MOVEMENT.
3. STEERING ABNORMALITIES.

Expert Reply: When you use the Bearing Buddy Bearing Protectors like # BB2441, so you do not need to take apart the wheel hub and repack the bearings. As you maintain the grease in the Bearing Buddy, it continues to fill the bore, so your bearings and spindle stay properly lubricated for proper function.

The best grease for travel trailer wheel bearings is the Lucas Oil 10301 Heavy Duty Grease. It lasts 4X longer than regular grease, is virtually waterproof, and is stable in all temperatures. It’s the ultimate grease for high-speed bearing.

Lucas Red ‘N’ Tacky Grease is a smooth, tacky, red lithium complex grease fortified with rust and oxidation inhibitors. It has good water resistance and washout properties. It has excellent mechanical stability and storage life….

For example, lithium grease can be applied both in chassis and wheel bearing applications of transport vehicles. Calcium-based greases have been rated high for water resistance but poor for elevated temperatures.
