Trailer Hub Grease Cap, 2.44" OD Drive In with Plug
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to take at look at the trailer hub drive-in easy lube grease caps. These have a 2.44 overall diameter. This part is for a quantity of two. These grease caps are designed for trailers that have easy lube axles. If you notice it has a center rubber plug that pops right out. This plug is removed to access the grease zerk fitting that is usually on the end of an easy lube spindle on an easy lube axle.
It saves you. You don't have to take your whole hub off to grease the bearings. What you can do is with this on the end of the hub, you just pop the center rubber plug out. It gives you access to that zerk fitting, put your grease gun in there and pump the grease in. These are commonly used on 4,400 pound to 6,000 pound axles.
The caps are made of a 22 gauge steel construction. Again the plugs are rubber. These are a drive-in installation and they do have a corrosion resistant zinc plating to them. Again the quantity is for two of them. Two critical measurements on the center cap are going to be the flange diameter which is measured from here to here and the overall height from the bottom to the very top. On this cap our flange diameter is 2.44" and the overall height from the bottom to the top is right at 1.52".
When this is installed onto the hub, all you have to do is pop off your rubber plug to access the zerk fitting. When you're done greasing the bearings, just put the rubber plug right back in. That should do it for the review of the trailer hub drive-in easy lube grease caps with the 2.44 overall diameter and for a quantity of two.

Fit perfectly
After purchasing several other hub grease caps I was finally able to find the correct one at etrailer.com. The price was very competitive(less than several others) and shipping was free and fast. I have always had positive experience while purchasing from etrailer.com
Easy ordering, fast shipping, and exactly what I wanted.
Great experience!
Ordered 15 Dust Caps 2/ rubber plug, all different sizes. I had 15 Dust Caps and plugs, thrown in 1 box. Not one is labeled, basically useless to me. Not happy at all.

Yes, unfortunately the grease caps do not typically come with individual labels. The easiest way to distinguish between them will be to measure the outer diameter to determine their sizes.
Excellent service with super fast deliv ery!
Great thanks
Over a year ago I had a used trailer given to me. It needed end caps, you call them grease caps. I bought, I installed, and now the trailer sits. ( haven't used it ) I'd send a picture but trailer is under a foot of ice and snow.
Exactly as Described. Dust Caps fit perfectly and the shipping was fast!

Works great!
After ordering the 2.44 size, twice, from another website, that I thought would be faster. Both orders showed up measuring 2.46 and would not fit the trailer. The time I thought I would save, turned into two returns before ordering from etrailer. Which of course fit perfectly. Don't trust the many vendors that ship through [online vendor]. I should have gone to etrailer for the correct parts the first time.

I am glad to hear that we could fix their mistake!
The parts were a fit for my rv. Lauren was very knowledgeable.
Fits like it should, seems to be the correct size
Replaced axles, new had EZ-Lube spindles and reused older drums and needed to retro fit with these Grease fitting access, dust caps. Worked perfectly
Good looking product, good tight fit. When installing the first time you'll need to file the burr off the edge and chamfer it slightly to get them started. They're still tight but you can persuade them with a wood block and hammer, without damage. They need to fit that tight and all four were uniform in fit, Thanks.

They keep the water out and the grease in!
