Expert Answers about Dexter

  • 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.

  • 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...

  • 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...

  • 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.

  • 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...

  • Can Taskmaster Modular Wheel LT589DMPWX be Mounted to a Dexter Hub with Flange Nuts
  • Yes, you could use flange nuts with wheel # LT589DMPWX but the hole size on this wheel is 5/8 and the hub and drum # 8-219-13UC3 has 9/16 inch studs. For a similar hub and drum with 5/8 inch studs you can use # 8-219-18UC3. It has the same bolt pattern and uses the same bearings and seal. It just has the 5/8 inch studs instead of 9/16.

  • 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...

  • 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 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.

  • Axle And Suspension Recommendation For Utility Trailer
  • I think the easiest way to get the parts you need for your trailer is to buy an axle kit that comes with the idler hubs, bearings, races, seals, grease caps, wheel studs, and lug nuts. For the weight you are saying you will be carrying I recommend starting with the Dexter Trailer Axle w/ Idler Hubs, part # 20545I-EZ-72-15. This system has a 5 on 4-1/2 bolt pattern so the tire/wheel combo I recommend is the Karrier ST205/75R14 Radial Trailer Tire with 14 inch White Wheel, part # AM32153....

  • Installation of Nev-R-Lube Bearing
  • You do not have to press the bearing in place when installing. You can use a dowel to tap it into place, this will help prevent damage to the bearing when installing. What's great about the Nev-R-Lube bearing # 31-71-3 is that you do not have to worry about seals, races, or repacking the bearings. I have linked the above mentioned Nev-R-Lube bearing to this page for your purchasing convenience.

  • Replacement Drum Brakes For A 89 Tandem Car Hauler
  • The axle part numbers are generally placed on a sticker located at the center point of the axle shaft. The part # 8-247 stamped into the hubs tell me that you have a 3,500 lb axle. To replace the drum brakes on your 3,500 lb Dexter axle you will have a few options. The two options entail the use of self-adjusting or manual brakes. The self-adjusting brakes will move the adjuster screw outward as the pads wear down to ensure optimal wearing and performance of the trailer's brakes, whereas...

  • 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...

  • 5 on 5 inch Bolt Pattern axle Hub to Replace a 5 on 4 1/2 inch Hub on Trailer
  • You will need to remove an existing wheel and hub. Once this is done clean the bearings and seal off and record the part numbers, be sure not to mix up the numbers for the inner and outer bearings. With the bearing part numbers and seal part number we will be able to cross reference the correct hub with a 5 on 5 bolt pattern to replace your trailers 5 on 4-1/2 bolt pattern hub. If you find that you have a # L68149 inner and a # L44649 outer bearing and a # 10-19 or # 58846 seal then...

  • Replacement Wheel Hub Recommendation for Carson Trailer with 5 on 5 Bolt Pattern and 3500 LB Axle
  • If your Carson trailer uses a standard spindle, you will need the Dexter Trailer Hub Assembly, # 84550BX. This hub assembly includes lug nuts, L68149 inner bearing and race, L44649 outer bearing and race, grease cap and grease seal. If you have a grease zerk at the end of your spindle, you will need our E-Z Lube Trailer Hub Assembly, # 84550UC1-EZ. This assembly also includes lug nuts, L68149 inner bearing and race, L44649 outer bearing and race, grease seal, but this kit includes an...

  • Replacement 72 Inch Long 2,000 Pound Trailer Axle
  • Trailer axle # 20545I-EZ-72-15 could fit in place of an axle with spring seat center spacing of 57-1/8 to 57-3/8 inches. At the very most the spring seats will have to be cut off and new ones, # TRSS175, welded on by a qualified professional welder for a nominal fee. Another option is an axle-less system, # A20RS545, which is rated for 2,000 pounds and comes with idler hubs. The suspension is built in. With this type of system you will not have to worry about replacing worn suspension parts.

  • Replacement 60-Inch 3500-lb Dexter Axle with 5-on-5-1/2-Inch Bolt Pattern
  • We do offer 60-inch replacement trailer axles from Dexter and both can be seen on the link provided. Note that both of these are rated for 2000-lbs. The 5-on-5-1/2-inch hub you referenced, part # 84555UC1, is intended for 3500-lb axles. The most important measurements for selecting a replacement axle are the hub face-to-hub face measurement (taken with the hubs in place) and the spring center-to-spring-center distance.

  • 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...

  • 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...

  • What Trailer Dimensions would the Dexter Trailer Axles # 20545I-EZ-72-15 Fit
  • The Dexter Trailer Axles # 20545I-EZ-72-15 that you referenced will fit a trailer that has the following dimensions. The axle it replaces will need to have a hub face to hub face dimension of 72 inches, you will need to measure the distance between the spring centers of the trailer, if that dimension is 58 inches it will connect to your suspension system. The wheel bolt pattern of your wheels will need to be 5 on 4-1/2 inch, and the capacity of this axle is 2,000 lbs. I attached...

  • 72 inch Long Trailer Axle Recommendation with 2,200 lb Capacity that can Fit 14 inch Wheels
  • The difference is the mounting flange on the hubs. Axles that have larger mounting flanges like the part # 20545I-EZ-72-15 can fit the larger wheels, whereas the # 20545I-EZ-72-10 has a small flange that doesn't match up to the bigger wheels. What you would want to do is go with the axle part # T20BTR-EZ-7258 that does not have hubs with it and then use the hubs # 8-258-50UC1-EZ that has the larger mounting flange on it and will give you the 2,200 lbs capacity you want in the correct size.

  • 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...

  • Recommended 72 Inch Axles And Brakes For Tandem Trailer
  • The 72 inch axles we offer have all got a weight capacity of 2,000 lbs. Also, none of the 72 inch axles have a brake mounting flange attached. You would need to have the components for a brake assembly installed on one of the axles. I recommend the Dexter Trailer Axle w/ Idler Hubs, part # 20545I-EZ-72-15, for the axle that you said you want free rolling. This has an EZ-Lube spindle with a 5 on 4-1/2 bolt pattern and has the bearings, races, seals and hubs included. This axle will work...

  • How to Choose the Correct Axle for a 2,000 lbs EZ Loader Trailer
  • We can most certainly help you to replace your axle and hubs on your 2,000 lbs trailer. If you are wanting to go with a standard axle you will need to pick one out that is the same length as the one you have now and that has the same hub-face-to-hub-face (A) and spring-center-to-spring-center (B) measurements of your current axle. I have attached a picture that demonstrates how to find these measurements. You will also need to pick if you need idler hubs or if they need the brake flange...

  • How Long Would an Axle have to be to Use 15 Inch Tires on a Trailer that is 60 Inches Wide
  • An ST205/75-15 tire will be about 8 inches wide. Assuming the wheels you use have a zero offset the minimum length of the axle, measured from hub face to hub face, would need to be 70 inches. The axles that we have that are 72 inches long are all either 2,000 or 2,200 pound axles.

You will also want to pick up a U-Bolt Kit # APUBR-10 for mounting your axle. Please check out the attached installation video for additional info. I was able to track down the specs for your trailer on-line and found that it uses slipper springs, so you'll want to go with one of the following. Choose...
