Trailer Hub Grease Cap, 1.988" OD Drive In
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today, we're going to take a look at the trailer hub driving grease caps. These have a 1.988 overall diameter. This part is for a quantity of two of them. These grease caps are used for your trailer hubs. They're commonly used on 3500 pound axles. These are made of a 22 gauge steel construction.
They are a drive-in installation. They have a corrosion resistant zinc plating to them. This is for a quantity of two. The two important measurements will be the flange diameter which is the overall diameter from this edge to this edge. If we put a ruler on that, it's going to come out to about 1.988 inches. The overall height from the bottom to the very top, that's going to be right at 1.156 inches.
That should do it for the review on the trailer hub driving grease caps with the 1.988 overall diameter, and it's for a quantity of two.

fITS GOOD
AAAAAAAAA+++++
These fit extremely tight. HIGHLY recommend the driver tool.
I ordered the product and it was shipped the next day. That was great as i wanted to get the trailer i was renovating out of my shop. I will use etrailer again because of the competitive pricing and the fast delivery. THANKS ETRAILER.
I order these parts every year when I repack my wheel bearings. They work well and with e-trailer it is easy to order.
Correct size replacement. Good quality and sturdy material.
The parts I need at a fair price
Overall experience with Paula with my over the phone ordering experience was fantastic. Unfortunately, none of the caps fit with my application. All were ever so slight too large.
Their just grease caps that cover your spindle nut, nothing special

It’s been great haven’t had any problems
as described.
Purchased to repair/replace Bolen's HT-20 tractor front wheel bearings.
Easily installed by driving into hub with scrap wood and hammer.
Affordable, relatively quick repair completed in between snow storms.
Thank you again eTrailer!

Worked great for my 1980 Bolens HT-20, thanks
I'm very pleased. The item was shipped and received quickly, and the diameter of the dust caps' diameters measured exactly what they were nominally listed as (1.98"). They were also cheaper with etrailer than anyplace else, in my online search.

I ordered the wrong size. I just tried to install them, and found that the bore is substantially larger. I have a Haul Master trailer from Harbor Freight. Do you have the right grease caps?

Does the job!
Thought these were right for the 3500lbs. drop axle with the EZ lube hubs but they were just a hair too big, had to bend the flange in a bit and then beat the hell out of 'em but they work. My old dust covers from my old axle were not deep enough and the EZ lube grease zerks would hit the inside of the cap.
I replaced all the bearings races seals and brakes on a small travel trailer. Bill P.at etrailer took my order and three days later I had everything in my hands. Great job Bill ! All the parts were exact replacements and the install went very smooth. There is video help on their website to show how to make the install easier. I have been dealing with etrailer for several years and have never had a bad experience. I was completely blown away by the pre assembled brakes . Backing plate, shoes, actuators, self adjusters and wiring all ready to bolt on. How much easier can it be? With the best prices, fast shipping and great help on line etrailer is the way to go.
Used these on a homemade flatbed reusing an old camper axle from the 50's the numbers on the old bearings did not cross to anything current, fortunately E Trailer has the specs online a few measurements with a caliper and you are in business. Thanks E Trailer
I was having a hard time finding this item and I am glad I looked on line.

Very well, My trailer is used on a weekly basis and this item has keep my trailer in road ready condition
Can't say enough good things about etrailer knowledge, service and speedy delivery. It's a regular encyclopedia for trailer parts. Ricky knew exactly what I needed, me being a first-timer on wheel bearing replacement and repacking. These grease caps took some pounding (with a rubber mallet) but went on my 8-91A Dexter hubs nice and tight without a dent.
Fit nice and snug
Well made. It gives a finishing touch to wheel hub. It is better than the hammered cover from previous owner.
Replaced the existing caps that had access to the grease fittings with a rubber grommet for a cover. I don't think greasing the bearings from the end of the axle is the way to go. I took some steel wool and roughed up the outside and painted them with black paint to match the hub.
Both caps flew off my trailer on the freeway. Had to get something different.
I ordered new wheel bearing kit’s, extra cotter pin’s and hub end cap’s because one fell off going down the road. All the parts were right and came in good condition I just installed them part yesterday everything went really good and easy. Thank you for having all he parts I needed.
The grease caps had a very snug fit on my trailer, so it took a lot of tapping to get them on, but that is a good thing. The old grease caps were apparently loose enough that one fell off. Great product, thank you!
Have them for about a year, no issues. Bought multiple for extras. True to size. I did need to lightly tap into place. I advise to buy a cheap micrometer to measure your original caps for proper sizing. Will buy again when needed.
Do you have a question about this Trailer Bearings Races Seals Cap?
