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.
