Expert Reply:

Since the Vault Hybrid Lubrication System uses a specific hybrid oil which you did not use when re-greasing your bearings, you will not want to reuse the Vault bearing protectors.

Instead I recommend going with the Bearing Buddy bearing protectors, but the correct one will be depend on the hub bore of your hubs.

I recommend using digital calipers like # PTW80157 to measure your hub bore as shown in the included diagram.

For example the the Bearing Buddy Bearing Protectors - Model 1980A # BB1980A-SS fit a hub bore of 1.980". If this matches your hub bore this would be a great replacement option.

If you can let me know the hub bore dimension of your hub I would be happy to recommend the correct bearing protector for you.

I included a video of the # BB1980A-SS for you to take a look at.
