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...

  • 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...

  • 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...

  • 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...

  • 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.

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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 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 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...

  • 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.

  • Sealed Trailer Bearing Availability
  • We have a few sealed trailer bearings. If you have a Neverlube bearing setup on your trailer then you would want the # 31-72-3 for a 35 mm bearing, #31-73-3 for 42 mm, or # 31-71-3 for 50 mm. The measurement that I mentioned for each bearing would be the inner diameter.

  • Availability of Metric ATV Hub Assembly With 4/110 Millimeter Lug Pattern

To help you identify your preferred bolt pattern I have linked an article at right. We also offer trailer wheels with pre-mounted tires to fit the axle kits we offer; a link is included for these as well. Bear in mind that the tires on your ATV may not be rated high enough...

  • Hub Recommendations to fit a BTR Spindle with 1.06 C and D Dimensions
  • Based on the C and D dimensions you listed you have a BTR spindle. The correct idler hub with a 5 on 4-1/2 inch bolt pattern that you would need would be the Trailer Hub Assembly # 8-259-5UC1-EZ. If you needed a hub and drum assembly for your spindle you would need the Trailer Hub and Drum Assembly # 8-257-5UC3. The # 34822545BX would not work on your spindle dimensions.

  • Can Trailer Hubs Replace Mobile Home Hubs
  • To positively determine if you can change your mobile home hubs with trailer hubs we will need to see if a trailer hub will fit your spindle. To determine this you will need either the bearing and seal part numbers from the bearings and seal on the spindle, or you can take some precise measurements to find the inner diameter of the bearings and seals. That being said, often times you will not be able to find replacement parts for a mobile home axle as they are designed for one time...

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...

  • How To Find Correct Replacement Bearings For Trailmaster Boat Trailer
  • I was unable to find any reference to a Dico 45264 hub. You will need to take some of the measurements to make sure you get the correct bearings and seals for your trailer. Trailer manufacturers use many different sizes when they build their systems and without precise measurements, we could not be 100 percent sure. Digital calipers are available at most tool supply stores. I have attached a drawing that shows where you can take the measurements. We would need to know the inner diameters...

  • Troubleshooting Uneven Trailer Tire Wear on Torsion Axle Trailer
  • The usual cause for trailer tires to wear more on the inside edges is indeed overloading. But if your 3500-lb torsion axle has not been overloaded then the most likely cause is a bent spindle (bent upwards, allowing the inside of the tire tread surface to make more contact with the road). If your bearings are not fully seated and if the hub is not secured with appropriate tension then this could allow enough play for the weight on the hub/spindle to tip the hubs/wheels/tires out of level. If...
