You lost a trailer hub cap, and now dirt and water can reach the bearings. This 2" lube-style dust cap restores hub protection and provides grease access through the removable center opening during bearing service.


Highlights

  • Restore Hub Protection: Replaces a worn or missing dust cap to keep grease in and contaminants out of your hub.
  • Grease Without Removing the Dust Cap: Remove the center plug (sold separately) to access the grease fitting while the dust cap remains installed.
  • Match the Correct Hub Bore: 2" diameter fits a matching hub bore for proper replacement.
  • Drive-In Replacement: Press fit installation restores your hub with a direct replacement dust cap.
  • Lube Style Design: Removable center opening provides access for routine bearing service.

Features to know about

Restore Hub Protection

A missing or damaged dust cap leaves your wheel bearings exposed to dirt, water, and grease loss. Left unprotected, contamination can shorten bearing life and lead to unnecessary maintenance. The drive-in design installs as a direct replacement to restore hub protection while maintaining convenient grease access through the removable center plug.

Grease Without Removing the Dust Cap

Remove the center plug (TX85RJ, sold separately) to access the grease fitting while the dust cap remains installed. This lets you add grease during bearing service without removing and reinstalling the entire dust cap.

Measure the Hub Bore Before Ordering

Correct fit starts with your hub bore measurement, not the trailer model or the old cap's nominal size. This dust cap fits a matching 2" hub bore, and the package includes 1 replacement dust cap for restoring a worn or missing part.

Video Transcript for Review of Terran Industries Trailer Bearings Races Seals Caps - Hub Dust Cap - TX42RJ

Hi, everyone. Steve here with the etrailer. Let's take a look at our Terran Industries two-inch trailer hub lube-style dust cap. So, folks, this will replace a worn or missing dust cap and this is what keeps the grease in and the contaminants out of your hub. Now as you can see, this is just the cap only. As you can see, there's a spot here for the rubber plug.

The rubber plug is not included. If you need that rubber plug dust cap, it's item number DC-RP sold separately and this will fit inside of this 1.18 inch dust cap hole. So, again, that plug will fit right in there. Now you want to match the correct hub bore with this. So, again, we're calling this a two-inch trailer hub; that's because it fits a two-inch trailer hub bore.

Obviously this part here is a little smaller. It's about 1.98, 1.99. If you have a set of calipers and you measure the diameter, you get about 1.98 or 1.99 and that will match the hub bore, giving you a proper fitment. I do highly recommend a tool that we sell separately to seat these dust caps in place. If you don't already have one, some people use a large socket, and they go right over this lip to press it in slowly or a block of wood.

I recommend the tool because it's ensuring it's grabbing that lip and you're getting an even push in, you're not going to be denting or messing up the cap. You're going to get quantity one, and that's going to wrap up our time together. I'm Steven. Thanks for watching.

They are the exact same as the 1.99 dust caps or actually even a touch smaller. The 1.99 caps came with a rubber plug to seal them. The 2.00 inch caps don’t come with any cap to actually keep dust out. That’s kind of a problem. Not to mention there’s no picture to show what you’re purchasing. I wasn’t going to say anything but you keep emailing me for a review so here you go.
