I would be happy to help you determine the correct Bearing Buddy Bearing Protectors for your 2019 Keystone Cougar 25RES 1/2 Ton 5th Wheel but you will need to take a measurement to confirm the hub bore diameter of your hubs.

To do this you will need to remove your current grease caps, and use digital calipers like # PTW80157 to measure the inside of your hub where the grease cap installs as shown in the included picture.

With this measurement you will be able to determine the correct Bearing Buddy.

For example if you find that your hub bore is 1.98" you will need the Bearing Buddy Bearing Protectors in Stainless Steel # BB1980A-SS or Chrome # BB1980A.

For grease I recommend LubriMatic LMX Industrial Strength Grease # L11390 as it is a premium grease designed for heavy duty applications and is perfect for trailer wheel bearings. You will also need a grease gun like the # L30200 to apply the grease.

Since I am not sure what grease you currently have in your bearings, and since some greases are not compatible with others I recommend removing your bearings the first time to remove all of the old grease and start fresh with the # L11390. Moving forward you will be able to just add grease as needed.

I included videos for each of the products mentioned for you to take a look at.
