Grease Cap for a Harbor Freight Trailer with 2.037 Inch - 2.042 Inch Hub Bore

Updated 07/18/2019 | Published 07/16/2019

Question:

Do you have grease caps for this trailer. I think it is 2.037 to 2.042 depending on who measured it. Also was told 51.18

The hub bore diameter of 2.037" - 2.042" is a rather uncommon size but Harbor Freight Trailers generally do use some rather oddball parts in which replacements are hard to find. Although we do not have any standard grease caps that will work for you based on the dimension that you provided, I would be willing to bet the Bearing Buddy Bearing Protectors part # BB2047 will fit as it is for a 2.047" hub bore. It can be really hard to measure the inside of a hub accurately and the digital caliper you are using could also be off a bit. The Bearing Buddy Bearing Protectors are super easy to add grease too which makes them a nice upgrade.
