You'll want to check both the hub bore diameter and confirm if it is threaded or non-threaded as you select a Bearing Buddy grease cap bearing protector for your hubs. The best way to measure the hub's inside bore is with a digital caliper like # PTW80157. This will give you the precise bore dimension to ensure a proper fit. And if your hubs are the threaded type you'll want to use a threaded Bearing Buddy like # BB1980T-SS which fits a hub bore of 1.980-inches.

I also linked an article that covers the types of lubricating grease available for various applications. You will want to keep track of the grease you use since different formulations are sometimes not compatible with one another. This too is covered in the linked article.
