Corrosion Resistance for Marine Use

This trailer hub 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"

  • Replacement Trailer Hub with Inner Bearing L44643 and Outer L44649 with 5 on 4-1/2 Bolt Pattern
    Actually the Dexter Hub part # 8-259-50 uses the same bearings you have and would work well for you. This also has the 5 on 4-1/2 inch bolt pattern you need as well.

  • Is Race Installed In Dexter Trailer Hub Assembly
    The race is pre-installed on the Dexter Axle Trailer Hub, part # 8-259-50. A separate tool is not required to use if you need to install a race. I am attaching a helpful article that explains how you can remove and install bearings, races, and seals in a hub. It is actually pretty easy, but you will want to use some caution to keep from damaging the new race.

  • Reasons for Wear on Inside of Trailer Tires
    Having the inside edges of your tires wear more quickly than the rest of the tread could have a few different causes. Trailer axles are arched, so that when the trailer is loaded, the tire contact patches sit fully on the ground. If the axle is overloaded, the axle can flex, placing the inside edges of the tires more in contact with the pavement than the center or outer edge of the tread. As you mentioned, it's also possible that the axle is bent. You'll also want to make sure that the...

  • How to Select Replacement Hubs for Utility Trailer
    Axle capacity is usually noted on a sticker or plate on the axle itself. The linked article includes a table with typical axle capacities based on their diameter; this information appears in the first column. Selecting new hubs requires you to match up some keys features. You need to match the axle capacity, wheel bolt pattern and the bearing set used inside the hubs. This matching of bearings is critical to ensure the new hub will fit on your spindles.

  • rebuilding boat trailer
    If both of the bearings on the existing hub are LM67048 then we will not have a match. This is likely an older hub design or an agricultural hub that is not used much any more. The best solution at this time is to replace the axle which surprisingly isn't as expensive as many people think. I have included a link below to the axles we carry.

  • Can Jayco Camper Trailer Swap from 4 Lug Hubs to 5 on 4-1/2 inch Hubs
    Pull one of the hubs off of your trailer and measure the diameter of the spindle where the bearings ride. If the diameter for both is 1.06 inches then the correct 5 on 4-1/2 inch hub would be the part # 8-259-50. If instead you have a spindle with a diameter of .99 inch you'd instead want the # 34822545BX.

  • Replacement Hub Recommendation for 2,200 lb Motorcycle Trailer Axle with 5 on 4-1/2" Bolt Pattern
    Thanks for all of the info! From the information you gave me it sounds like you're needing the Dexter Trailer Idler Hub Assembly for 2,200-lb Axles - 5 on 4-1/2 # 8-259-50UC1, but I do recommend pulling your hub and checking the part numbers on the bearings and seal or measuring the spindle where the bearings and seal ride to make sure it fits. Here are the bearings and seal used for this hub: Inner and outer bearings - L44649 (1.063" inner diameter) Grease seal - 10-9 (1.5" inner diameter...

  • Recommended 2200 lb Hubs For 12 Inch Wheels
    On your boat trailer with 12 inch wheels, if you want to install 2200 lb hubs that show a 13-15 inch wheel capacity, your ride may be effected or you may have difficulty installing the wheels as the face of the hub is sized differently. I recommend using 2200 lb hubs that are a fit for your 12 inch wheels like the Trailer Hub for 2,000-lb and 2,200-lb Axles - 5 on 4-1/2 - 8" - 12" Wheels - Galvanized # 8-259-50 or # 8-259-50UC1-EZ for an EZ Lube axle.

We already know your is 5 on 4-1/2 inch. Next thing you will need to know is what spindle you have on your trailer.

  • What is the Torque Rating for the Castle Nut to Hold on Trailer Idler Hub # 8-259-50UC1-EZ
    I checked with Dexter and on light duty hubs such as # 8-259-50UC1-EZ they recommend the castle nut be tightened to 50 foot pounds. If that makes it too tight then back off the nut some until it is no longer overly tight and the hub can be spun by hand.

This will allow you to replace the hubs with the Dexter Trailer Idler Hub Assembly # 8-259-50UC1 as long as your axles have not been modified or replaced from the time they left the factory.

  • Hubs for 13 Inch Tire with 5-1/2 Hub Flange Diameter
    I spoke with an engineer from our hub manufacturer, Dexter, and they do not recommend using a hub for 8-12 inch wheels with a 13 inch wheel. However, they said that they do not make a hub for 13 inch wheels that has a hub flange diameter of smaller than 6-1/2 inches. The best option that we can recommend is to replace your wheels to fit the hubs we offer. The hub designed for smaller tires with a smaller hub flange will technically fit but, there may be no warranty support if something...

  • 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 you...

  • Can The Capacity Of An Axle Be Determined By Looking At The Hubs?
    Though it is sometimes possible to identify an axle's capacity based of the hub, it is not always 100% accurate. Due to this, I tell people to not rely on just this alone. As a quick example, if you look at the Dexter Hub # 8-259-50BTUC1 and # 8-259-50UC1-EZ, they will both use the exact same 8-259 hub. However, the # 8-259-50BTUC1 will use the # L44643 inner and outer bearing and is rated for use on a 2,000 pound axle. The # 8-259-50UC1-EZ will use the # L44649 inner and outer bearing...
