E-Z Lube-Compatible Hub for Simple Lubrication

The grease cap on this hub is specially designed to work with your Dexter E-Z Lube axle to make lubricating bearings quick and easy. Just remove the plug on the grease cap, attach a grease gun to the zerk fitting on the end of the spindle, and inject the grease. It will flow easily to both inner and outer bearings. Not only does this make lubricating the bearings easy, but it also helps to prevent corrosion of the hub. This is because you can lubricate the bearings without the mess of taking apart the entire assembly.

Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Carrie did an excellent job in establishing exactly what I needed, and the installation of a new axle and hubs went perfectly. One note I would make is that the nut lock for both of the spindles remained lodged in the plastic spindle protectors and I almost missed finding them. A note in the packaging might be helpful.

- 84550UC1-EZ

I used these for a trail trailer that gets hammered on behind a highly modified Jeep and these hubs have no runout or issues of any kind. Great hubs for the money.

Great service !!!!

The Curt Trailer Hitch Receiver arrived, took about a week with free shipping. It was well packaged and the other items (Cotter Pin, 1/8" x 1-3/4" - 165649, Mounting Bracket 4-Pole Flat – 18144, 4-Pole Trailer Connector Cover – 20112, and Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 5 - Pre-Greased - 84550UC1-EZ) in my order, which arrived without any issues. I am an avid shopper online, always looking for the best deal not only on price but also total cost with shipping. This is not my first order, and most likely will not be my last. The hitch receiver was well made and has a good paint job. It fit my 2003 Toyota Tacoma snugly, however, I was able to mount it by myself in approximately a little more than an hour. The stock bumper had a towing capacity of 3,500 lbs., however it always had me worried since it is a 17-year old bumper with a few dents from previous owners. Now I do not have to worry about it and have a great place to connect the safety chains without having to get under my truck every time I connect to a trailer to secure it correctly. Read, who needs to read with a great installation video on; although the instructions were easy to read and refer to if I had any questions. After installation, the hitch receiver looked cleaner, sharper than the rest of my truck, which forced me to wash my truck!

Replaced all 4 hubs on an old flatbed trailer with these hubs. They arrived in 2 days, installed easily, and the price was great. I have bought from etrailer many times and they are always excellent to deal with.

Excellent as usual from etrailer.

Excellent replacement axel. All parts were in kit and fit like they should. Extra long spindel makes it a good choice of any axel repair. Fast shipping.
