Expert Answers about Dexter

  • How to Determine Axle Position when Building a Trailer
  • There is an easy way to determine axle placement on a trailer. Take a look at the picture I have included. Just plug in the numbers and complete the formula to determine the axle placement. The other factor that is going to come into play is the springs that you are going to use. Once you have the measurements all figured out you can determine which springs are going to work with that set up. I have also included a link to our double-eye suspension FAQ article to the right.

  • How to Measure for the Correct Replacement Trailer Axles
  • Are they really bent, or do they have an arch in them? Most trailer axles are specifically designed to they're arched. When weight is applied to the axles, they'll flatten which will give the tire tread full contact with the pavement. If the axles weren't arched, the tires would contact the pavement with the inside edges once weight was applied to the axle. This would cause uneven tire wear. If you determine that the axle is indeed bent, you'll need the following information to get the...

  • Can a Different Axle be Installed on a Harbor Freight Trailer Frame that is 48 Inches Wide
  • Yes, you could use axle # 20440I-EZ-60 for your trailer project! The width of your trailer is the same as the spring seat center to center measurement on the axle (48 inches). The hubs on this axle will accommodate up to 12 inch wheels with a 4 on 4 bolt pattern. I have included a link to a video review of the axle for you.

  • Troubleshooting Overheating Hubs on a Trailer With New Bearings and Grease
  • Hubs will heat up when driving, but if it feels like they are getting too hot, then you will want to look at a few things on your hub. My guess is that the spindle nut is too tight and the added stress on the bearings is overheating the bearings and hub and could be causing damage to the bearings. When you install the castle nut you will want to tighten the spindle nut while turning the hub. When there is a slight bind on the bearing, the parts are seated correctly. Back the nut off...

  • How to Determine The Correct Replacement Trailer Hubs by Bearing Numbers or Spindle Size
  • The best way to determine which replacement hubs you need for your trailer would be to remove one of the hubs and retrieve the bearings. Find the numbers stamped into the bearings and with those we will be able to get you the correct hubs. If you are unable to retrieve the bearing numbers, you can take measurements of the spindle. I have included a link to our spindle main page. At the top of the page is a diagram showing all of the measurements we would need to find the correct hubs...

  • Parts Needed to Install Electric Trailer Brakes on a Pop-Up Camper
  • You have compatible hub and brake assemblies selected. The brake assemblies, # 23-48 right hand, and # 23-47 left hand, will mount to a 4 bolt flange that has bolt holes 2-7/8 inches apart on center. You will need to make sure your existing bearings and seal match the bearings and seal in the hub and drum you selected, # 8-257-5UC3-EZ, and that the wheel bolt pattern, 5 on 4-1/2 inches, matches also. The trailer hub and drum # 8-257-5UC3-EZ is designed for use on an EZ lube axle with grease...

  • Replacement 3500 Pound Trailer Axle for a Travel Trailer
  • All of the 3500 pound axles that we carry that also have electric brakes are too long for the measurements you have provided. But we do carry just the most popular sizes. One option is to instead use a Timbren axle-less system, # A35RD545E. Or you could visit a local tractor or trailer supply store and order a custom axle to your specifications.

  • How to Determine Hanger Spacing for Tandem Axle Trailer Suspension with 26 Inch Springs
  • Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are based on our preassembled kits, so we will use that as a foundation for your setup. First, I would either replace all of the front and rear hangers with 2-1/2 inch tall hangers like part # 115918 or replace just the center hangers with 2-1/2...

  • Replacement Dexter 8-258 Hub Recommendation
  • The hub part number # 8-258-5UC1-EZ that you referenced would be the correct hub for you as it would be an exact replacement to what you currently have. It comes with a set of matching bearings to fit your spindle. The spindle nut/washer kit you would need would be the part # RG05-100.

  • How to Find the Overall Width of an Axle with Tires for an 8ft Trailer
  • The final width (with tires) of the Dexter Trailer Axle, # 35545I-EZ-89, will depend on the wheel and tire size you intend to use. You would simply add the width of one tire (assuming your wheels have a zero offset) to the 89 inch hub face dimension of this axle to find the total width. For example, if you have 6 inch wide tires, then you would add 6 inches to 89 which gives you a total width of 95 inches. When choosing a replacement axle, it is important to choose an axle that has...

  • Replacing a Lippert 3,500 lb Leaf Spring Axle with a Dexter 3,500 lb Leaf Spring Axle
  • The Dexter Trailer Axle, part # 35545E-ST-EZ-89, is similar to the Lippert LC135-SB-85.0-68.5 axle, but it is not a direct replacement. Both axles are 3,500 lb leaf spring tubular axles, but they are different lengths. The Dexter axle is slightly longer, which means the wheels would stick out further and the spring center is wider. Your axle has a hub face measurement of 85 inches and the Dexter axle has a hub face measurement of 89 inches (see photo). The wheels will stick out about 2...

  • Selecting a New Axle, Wheels and Tires for a 4 x 8-Foot Utility Trailer
  • An easy way to replace your axle is to use a complete kit such as Dexter # 20545I-EZ-60-15. This kit consists of the 60-inch axle, idler hubs, bearings, seals, lug nuts and grease caps - and even grease. This axle is rated for 2200-lbs and its spring centers are at 48-inches. Its hubs have the same 5-on-4-1/2-inch bolt pattern as the wheel/tire you referenced, part # AM31985 from Kenda. This kit will work with 13-inch wheels. Note that you will need to weld on new spring seats on top of...

  • Adding Modern Hub/Drum/Brake Assemblies to 1965 Vintage Trailer
  • Because it can indeed be a challenge to find replacement parts for trailers like yours that are of a substantial age, your easiest route will likely be to replace the axle along with your hubs/drums/brakes. This way all components will be fresh and known to be in good condition. They will also have the same working life. Replacing the axle/spindles will also simplify the process of finding the other items and of maintaining the updated trailer in the coming years. You will need to determine...

  • Replacement Trailer Axle Recommendation for an EZ Loader Boat Trailer
  • You will need to measure your axles first though. The axles we offer are 89 inches from hub face to hub face and 74 inches from spring center to spring center. If your axles match these dimensions the part # T3584F-EZ-8974 would be a great choice for a hubless axle. If you wanted an axle that came with hub/drums that have a 5 on 4-1/2 inch bolt pattern you would want the # 35545E-ST-EZ-89. If you need axles with different dimensions you will need to check with your local trailer...

  • Difference Between Idler and Braking Axle
  • A brake axle would have brakes, either electric or hydraulic drum or disc brakes while an idler hub would have no brakes. Many times, a tandem axle trailer will have one braking axle and one idler axle. The 3500 lb capacity # 35545I-EZ-89 axle you were looking at comes with idler hubs, but because it has brake mounting flanges, brake assemblies and hub/drums could be added at a later date if necessary. To find a replacement axle, you'd need to measure the hub face to hub face dimension...

  • Replacement Axle for Constructing Teardrop Trailer on Utility Trailer Frame
  • We sell axle beams alone and also complete axle kits that also include hubs, bearings, seals etc. The key is to confirm the weight rating of the existing axle (check it's safety sticker) and it's dimensions so you can choose a replacement with equal capacity; changing the axle to a higher-rated one does not increase the trailer's weight capacity since this is determined by many items, not just the axle itself. Please refer to the linked image for help with axle dimensions.. I have linked...

  • Recommended Axle Replacement For 5200 lb Dexter Axles With Electric Brakes
  • The only axles we carry that are that 5200 lb capacity are the Timbren Axle-less Suspension System. For your application, I recommend the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03. This will replace your leaf springs and your axle. It has a brake flange and is compatible with standard hubs and drums. If there isn't a crossmember where you install your axle, you will need to use a 2 inch by 3 inch steel tubing to connect the...

  • Converting 3500 lb Axle from Idler Hubs to Electric Brakes
  • The brake mounting flanges, whether they be 4 or 5 bolt, have a standard hole spacing to fit their appropriate brake assembly. No worries about the brake assembly matching with the existing one on your axle. A 3500 lb axle like what you have will use a 4 bolt flange. You will need to get the numbers that are stamped on your existing bearings, in order to confirm the fit of the # 84557UC3. Your current bearings will need to match the bearings of the replacement hub. The # 84557UC3 uses...

  • Recommended Replacement Axle For Carry-On 6 X 12 Utility Trailer
  • To make sure you get the right replacement axle on your Carry-On trailer you need to know a couple thins. First you need to know the spring-to-spring measurement. Then you need to know the hub face to hub face measurement. The Dexter Trailer Axle w/ Electric Brakes, part # 35545E-ST-EZ-89 has a spring-center-to-spring-center length of 74-inches and a hub-face to hub-face measurement of 89-inches. If these measurements match your trailer then this would work great for you. If the...

  • Replacement Trailer Hub for Dexter 8-259 Idler Hub
  • We will need to go by the bearings used in your current hub. If your bearings are L44649 inner and outer then you can use hub # 8-258-5UC1-EZ. It and hub # 8-259-5UC1-EZ use the same bearings, both have a 5 on 4-1/2 bolt pattern, and both are for 2,000 pound axles.

  • Replacement Hub and Drum Assembly for a Dexter 10K General Duty Axle 387A Inner and 25580 Outer
  • We have exactly what you are looking for. If your axles were made before 07-01-2009, then you have the old style 2-piece hub and drums, so you will want the Complete Hub Assembly, # 8-288-3UC1. Keep in mind, this does not include the drum. If you also need the drum, then you will want part # 9-44-1 for a non-ABS drum or part # 9-44-3 for a drum with the ABS exciter ring installed and 8 drum mounting bolts, # 7-245. The hub assembly comes with the races already installed and it includes...

  • Replacement Trailer Hub for a Reliable Hub BT-150A
  • I was able to find the bearing information for your Reliable BT-150A hub and it looks like it used inner/outer bearings of L44643 so the trailer hub part # 34822545BX would be the correct hub to use. This hub also has a 5 on 4-1/2 inch bolt pattern.

  • Recommended Clearance Between Trailer Frame and Axle
  • The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. You should have sufficient clearance with your loaded trailer, as leaf springs only tend to deflect 1-1/2 inch when carrying a load.
