Axle Dimensions

Hub Face and Spring Center Measurements on Standard Trailer Axle

There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle.

The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.

If you are replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.

E-Z Lube Spindles Make Lubrication Simple

The E-Z Lube spindles on this axle are meant to work with E-Z Lube-compatible hubs to make lubricating your bearings quick and easy. Each E-Z Lube spindle has a zerk fitting on the end. And every E-Z Lube hub comes with a grease cap that has an easy-to-remove rubber plug. Just pop out the plug on the cap to access the zerk on the spindle. When you inject grease into the zerk with a grease gun, the grease will flow to both the inner and outer bearings of the hub, lubricating the bearings and forcing out old, ineffective grease. Once you see new grease beginning to be pushed out, you know that your bearings are fully lubricated. This means that you can lubricate the bearings without the mess of taking apart the entire assembly.

Dexter Axles

Dexter axles are made of high-strength steel and come with spindles and spring seats welded on. The spring seats are attached to the underside of the axle so that the leaf springs (sold separately) can mount beneath the axle. This axle is also built with drop spindles, which will lower the ride height of your trailer to allow for easier loading and unloading.

Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer's tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.

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"

Do you have a question about this Trailer Axle?

  • Replacement Axle with Hubs & Brakes for Wells Cargo Tandem-Axle Enclosed Trailer FT85162
  • The Wells Cargo website indicates that their enclosed tandem-axle trailer model FT85162 has a GVWR of 7000-lbs so it has two 3500-lb axles. The specs did not indicate axle length. We have several 3500-lb axle kits with hubs and brakes that are shown on the linked page. All have 5-on-4-1/2 hubs and electric drum brakes. Two lengths are offered, the 89-inch size like # 35545E-ST-89 and the 95-inch length such as # 7359765-EB. These measurements are from hub face to hub face. Please...

  • Width of Dexter Trailer Axle With Electric Brakes and 4 Drop
  • The Dexter Trailer Axle with Electric Brakes - 4" Drop # 8327812-EB measures 89 inches hub face to hub face and about 92 inches if you are including the hub being on, or from spindle to spindle. That said, once the wheel and tire are on the measurement is going to be different depending the sizes of those. As a note, I did want to mention that to choose the correct axle size you will want to find the axle with the same spring center to spring center and hub face to hub face dimensions as...

  • 3,500 lb Axles Compatible With Timbren Silent Ride Suspension
  • Yes, we do have axles with electric brakes that are compatible with the Timbren Silent Ride Suspension for Tandem Axle Trailers w/ 2-3/8" Round Axles # TSR7000T04. A 2-3/8" round axle will be one with a 3,500 lb capacity and we carry a number of options, which I will list for you below. The only thing to be aware of is that in order to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center...

  • Where is Drop Measured From for Trailer Axle With Drop Spindle?
  • The Dexter Trailer Axle w/ Electric Brakes - 4" Drop - E-Z Lube # 8327812-EB has spindles that drop 4 inches from the center of the trailer axle beam. What this means is that you get an additional 4 inches of clearance from the center of the beam to the spindle.

  • Can Electric Brakes be Used on a Boat Trailer
  • Modern electric brakes such as those that come with Dexter axle # 8327812-EB can be used on boat trailers. However, I strongly recommend that before submerging the trailer in the water disconnect the trailer's electrical plug from the tow vehicle. No need to take any chances; safety first! If there was a problem caused by the water it would more than likely be the result of exposed wiring somewhere and not the electromagnets themselves. It is recommended to use heat shrink tubing or...

  • Recommended Replacement Axle for Snowbear Trailer
  • We do not have a Dexter axle with the 75-5/8 hub face and 64 inch spring centers. What I have that will work as a replacement are the Timbren Axle-less Suspension System like # A35RS545E which includes the brake assemblies, hub/drum assemblies, suspension, and EZ-Lube spindles. These are universal fit kits that mount directly to the trailer frame. All that is needed is a 2 inch square bar that is cut to the custom length (not included) that fits into the integrated holes in the assemblies....

  • Parts Needed to Switch Out Mobile Home Axles for New Axles with Electric Brakes
  • I have a solution for you, and it looks like you're aware that because these are mobile home axles, you will need to replace everything- the only caveat is that since the dimensions you provided are not standard, any axle you use will require some modifications. You will be able to use the Dexter # 8327812-EB which is an 89" long axle with 74" spring center to spring center; you will need to have the spring seats moved to match your 77" center on center location by a certified welder.

  • Can Spring Seat of Axle be Moved a Couple Inches to Allow Axle to Fit on Trailer
  • You can move spring seats by having them cut off and rewelded in the correct location so the Dexter axle part # 8327812-EB that you referenced would work for you as long as you'd be willing to do that step. With this axle being 1 inch shorter in length than what you have now you'd have 1/2 an inch less clearance from the inside of the tire sidewall to the frame of the trailer.
