Corrosion Resistance for Marine Use

This trailer hub assembly has a zinc coating that resists corrosion, making it ideal for use on your boat or snowmobile trailer. All GAL-DEX hubs undergo a test in which they are sprayed with a 5-percent salt solution to determine corrosion resistance over time. These products are able to withstand 500 hours of constant exposure to the saltwater mist. This 500-hour salt spray rating indicates that a product is not only durable enough to last in freshwater environments, but it can also be used on trailers that come into contact with saltwater.


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"

Just what I needed to replace the original worn out hubs on my small trailer. Parts arrived quickly in great condition and were a direct replacement. These hubs are actually better than the original hubs, they are galvanized not painted and will better protect from rusting, they also came with 1/2-20 threaded studs compared with threaded bolts on the original hubs. The idler hubs also came with all the required components to repair my small trailer.

I have not yet installed them but have unpacked and took measurements. The only issue I have is the grease seal ID is .25 to large but that is most likely my fault during the order, I have the right size grease seals coming. The hub is solid and the bearings fit real nice, no slop. This is for a boat trailer which goes back and forth to a very rural camp so it gets bounced around a lot, time will tell how these hold up. The original hub and bearings are ok and will be my field spare should I need it, slip one hub off and the other on, tighten and go. I like the stud with lug nut to hold the rim rather than original bolt into the hub, easier for tire mounting and I can put a locking lug nut on as well, personal preference. This seemed to be the most cost effective means, all one package, just watch the size of the individual parts to make sure you get all the parts the correct size. etrailer.com packed the parts well, nothing flopping around or damaged. No complaints, now the dirty part, replacing the old with new.


Comments
Still on the trailer and working out well. I have put some hard miles on them and they seem to be holding up. Just shot some grease in them before the next trip.

These are very well constructed and etrailer does a good job at putting together a kit that contains everything you need. You will have to keep though your old washer, nut, and pin. Make sure you are ordering not only the right size of bearings, but also the grease seal. Some not-so-standard hubs have mismatched seal sizes. Measure your spindle and your seal seat. If your spindle is larger in diameter than the 1” (1.058”) this is the right kit for you. But also measure your seal seat. This kit shipped with a seal that fits a seat that’s 1.5” in diameter. If Yours is closer to 1 ¼” you are going to need a different seal. etrailer quickly rushed out those for me!

I received my hubs last week, shipping was nice and fast, and I installed them over the weekend. Kits were complete and everything fit perfectly. The only negative comment I would make is that the hubs do not look like they do in the video or picture. Instead of a "round" shape hub, they are a "star" shape hub, which made me think I had received the wrong ones. Once I pulled off my old ones and checked all the measurements I realized the difference between the two was purely cosmetic. Very happy!

  • Selecting Replacement Hubs for 1963 Travel Trailer
    Thank you for the information from your vintage travel trailer's existing hub assembly. This is likely a casting number and will not give us what we need to find you correct replacement hubs, but it is not hard to determine correct new hubs. You will definitely want to replace both hubs. Things you need to match up are the hub bolt pattern, the axle weight rating and the bearing numbers. The linked article will help you with identifying the bolt pattern, the axle should have a sticker...

  • Replacement Hubs for 1994 Coleman Destiny Pop-Up Camper Trailer
    Thank you for providing the details about your 1994 Coleman Destiny's axle and hubs. It is often a lot easier to just replace the complete hub than to pry out the old bearings and races and to re-install everything. New hubs also give you the confidence that comes from knowing all your components are new and in good shape. On the page I linked you can view all compatible idler hubs in your 5-on-4-1/2 bolt pattern that are rated for a 2200-lb axle. All of these idler hubs use your L44649...

    Thanks for the information you gave. I recommend the Trailer Hub Assembly for 8" to 12" Wheels - 5 on 4-1/2 with GAL-DEX Coating # 8-259-50UC1. These Dexter assemblies have a galvanized coating to assist since your trailer is going to be used in water. You may also want to consider the Bearing Buddy Bearing Protectors - Model 1980A-SS w/ Auto Check - Stainless Steel (Pair) # BB1980A-SS which will protect your bearings while submerged in water or salt water. These have a built in grease...

  • Replacement Hub for 1989 Ranger Trailer
    Judging by your photo, your trailer would use an idler hub, not a hub drum. Assuming you have 5 lug on 4-1/2 inch bolt circle wheels that use an # L44649 inner and outer wheel bearing, you have a few choices. Rather than the painted hub, I'd recommend going with a galvanized hub for greater corrosion resistance. Dexter hubs are manufactured in the US, which is what I'd recommend. For an 8, 10 or a 12 inch wheel, use # 8-259-50UC1 for a standard spindle or # 8-259-50UC1-EZ for the EZ...

  • 5 Lug Hub That Can Fit Spindle with BTR Dimensions
    Thanks for the picture you included that has the dimensions of your spindle. Based on that you do have a BTR spindle so for a hub with the 5 lug bolt pattern you wan you'd need the # 8-259-50UC1 and you'd be set. Your spindle not having a grease fitting is also not a big deal at all. That does not affect the fit of the hub to the spindle at all.

  • Looking for Replacement Hubs for Boat Trailer with 1.06 Inch Diameter Spindles
    Since you successfully measured your spindles, it sounds like you might have a digital caliper lying around somewhere. Measure the hub bore (inside diameter of hub where grease cap sits). If this diameter is 1.98 inches, your existing bearings are # L44649, in which case the # 8-258-5UC1 hub you referenced would indeed be a correct replacement. Since the hubs are going on a boat trailer, I'd recommend you use galvanized hubs like part # 8-259-50UC1. The hubs are identical to the ones...

  • Where To Find Numbers For Replacement Bearings On Utility Trailer
    Since the axle you have is a Dexter Model 8259 you can choose one of the hub assemblies we offer from the attached product page. If you have an EZ-Lube axle on your trailer you may want to check out part # 8-259-5UC1-EZ, or part # 8-259-50UC1-EZ. If you do not have an EZ-Lube axle take a look at part # 8-259-5UC1 or part # 8-259-50UC1. I have attached links to some product review videos for these kits you can take a look at.

    In order to spec the correct replacement wheel studs, I'd need the dimensions from one of your existing wheel studs, as shown in the provided diagram. I spoke with the nice folks at Triton Trailers to find the specifics about your existing hubs. For a replacement hub, I'd recommend part # 8-259-50UC1 which is compatible with a 2200 lb axle.

A galvanized version isn't offered, but there's one available in a 5 lug on 4-1/2 bolt circle, part # 8-259-50UC1 for 8-12 inch wheels or # 8-258-50UC1 for 13-15 inch wheels.

  • Replacement Hub and Bearing Recommendations for Trailer Hub with L44649 Bearings
    Since both of your bearings are # L44649 you would want a coated hub like the part # 8-259-50UC1 since this is for a boat trailer. This hub has a Gal-Dex coating to fight corrosion. This hub has a 5 on 4-1/2 inch bolt pattern. If instead you have 4 on 4 inch bolt pattern you would want the part # 8-91-05UC1-EZ. Or for just the bearings you would want the part # L44649 that I mentioned. Or for a bearing kit with new seals and races you would want part # BK1-150. The included seal is...
