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"

Most mobile home axles are built with an odd sized spindle that do not have any available hubs with a traditional trailer wheel bolt pattern. The only want to be sure is to either get the bearing numbers off the old bearings or to measure the spindle diameters with a dial or digital caliper, at least to the 1/100th. Bearing numbers is by far the easiest. Check out the link to the spindle below. There is a diagram that shows the measurements that you will need to take in order to positively determine whether or not a hub is available.

Ask the Experts about this Dexter Axle Trailer Hubs and Drums

  • 8 on 6-1/2 inch Dexter Trailer Hub with 2-1/4 inch Inner Diameter Grease Seal
    Yes, the grease seal part # GS-2250DL would work in the Trailer Hub part # 8-219-4UC3 that you referenced. Or to order the same hub with the right seal for your application you would want the Hub part # 42866UC3 as this comes with the #GS-2250DL.

  • Number 42 Spindle Recommendation
    We do have a Dexter number 42 spindle. For a standard spindle you would want the part # R50642. For the EZ lube version you would want the part # R50342EZ. This comes with a brake mounting flange. The seal inner diameter needed for this would be 2.24. The bearing dimensions you referenced are correct.

  • How to Pick Out a 8 Lug Hub to fit a 5,200 lb Dexter Axle
    It is hard for me to say with absolute certainty, but most likely the part # 8-219-4UC3 would work for your 5,200 lb Dexter axle since this hub is designed to fit most 5,200 lb Dexter axles. But the only way to verify this would be to either pull your hubs and measure the spindles or get the bearing numbers. This is especially true since you said your outer bearing is a different number than what the # 8-219-4UC3 has. A lot of times the 4,800 and 5,200 axles are the same with the only...

  • Trailer Hub Stud Recommendation for 5,200 lb Lippert Hub
    I wasn't able to find your specific part number hub but if you have a 5,200 lb hub with a 6 on 5-1/2 inch bolt pattern you are going to need a 1/2 inch drive in stud. If your existing drive in studs are 1-13/16 inches long (measurement B in picture) you will need the Replacement Trailer Hub Wheel Studs, item # RG03-040. If your existing drive in studs are 2-1/2 inches long (measurement B in picture) you will need the Replacement Trailer Hub Wheel Studs, item # RG03-080.

  • Should Trailer Bearings Spin on the Spindle they are Installed On
    When installed properly the portion of the bearing that attaches to the spindle should not spin. Only the outer portion should be spinning. It's pretty easy to overtighten a spindle nut since they don't have to be very tight so that would be the most likely situation. When our installers replace a trailer hub, there isn't a set torque spec used when tightening the spindle nut. The hub is placed on the spindle, making sure the inner and outer bearings are correctly seated. The spindle...

  • Replacement Hubs and Drums and Brakes for Lippert 6,000 Pound Trailer Axles
    Since you have 6K Lippert axles with an 8 on 6-1/2 bolt pattern for the wheels and hubs I assume that the inner bearing is 25580 and the outer is 14125A. It would be worth checking just to be sure. If you have regular axles with no grease fittings at each end then you can use # 8-219-4UC3. If you do have EZ Lube axles with the grease fittings use # 8-219-4UC3-EZ. For either hub and drum assembly you can use right hand side brake assembly # AKEBRK-7R-SA and left hand side # AKEBRK-7L-SA.

  • How to Choose the Correct Replacement Hubs and Brakes for Keystone Montana Fifth Wheel
    Thank you for the information you provided. Based on the sticker on the brakes I can tell you that the replacement brakes you need are the Dexter Electric Trailer Brake Assembly - 12" - Right Hand # 23-106 and Left Hand # 23-105. The brakes are for 6,000 lb axles so based on that and the 8-219 you provided I was able to narrow down what hub you need, but there is still a bit more info to get the correct part - the bearings and wheel bolt pattern. For example, the Dexter Trailer Hub...

  • Wet Trailer Suspension Bolt for Tandem Axle 5th Wheel Trailer
    Yes! You are looking for what is called a wet bolt. We have different ones available depending on what you need. For a 9/16 inch wet bolt that is 3 inches long use # 126B2. This is the most common size and is likely what you will need. But I have also linked all of the suspension bolts (some are wet bolts and some are not) so you can see all the options.

  • Selecting Correct Bearing Buddy for 8-Lug Hub on 7000-lb Axle on PJ Dump Trailer
    Selecting the correct Bearing Buddy bearing protector for your 8-lug hubs requires that you know the hub's bore where the grease cap (or Bearing Buddy) fits. This requires using a precision digital or dial caliper and measurement to the nearest thousandth - 3 decimal points. You also want to note whether you hubs are threaded or non-threaded as we offer both types of Bearing Buddy. For example, we offer an 8-lug hub for 7K axles, part # 8-219-4UC3, and this hub's bore happens to be 2.720-inches...

  • Outer Diameter of Center Bore Trailer Hub and Drum Assembly 5,200-lb to 7,000-lb Axles - 8 on 6-1/2
    The pilot hole on a wheel would have to be 4.75 inches or larger for hub and drum assembly # 8-219-4UC3. It can be larger because this hub uses lug nuts to secure and center the wheel on the hub (lugcentric). If it just had holes for wheel bolts (hubcentric) then the pilot hole would have to be exact.

  • How to Correct for Extreme Stress and Bearing Damage on 5200-Lb Torsion Axle on Tandem Trailer
    If your axle castle nuts are backing off and shearing the cotter pin then this extreme force could be coming from one or more possible causes. I suggest you check your rear axle tire treads for signs of uneven wear. If you notice more wear on the inside edges of the tires this could indicate any of several possible root causes, an overloaded axle, damaged axle or bent spindles. Any one of these conditions could result in wheel misalignment. This condition could in turn lead to excessive...

  • Tightness Recommendation for Castle Nut on Trailer Hub
    I'd go on the tighter side of what you mentioned where there's no play yet you can still spin the wheel several times on one push. You might put your hand on the hub to feel if it's getting overly warm next trip you take but I believe that's the best spot you'll have.

These are 12 inch by 2 inch electric brake assemblies that will mount to the standard 5-bolt pattern brake mounting flanges. The way to determine what hub and drum you need is to remove the old hub and find the bearing and seal part numbers. These part numbers will be stamped into the metal of the bearings and most likely in the rubber of the grease seal. This will...

  • Proper Way to Tighten Trailer Spindle of Castle Nut
    After you've packed the bearings and assembled everything, carefully slide the hub assembly onto the spindle and install the outer bearing. Install the spindle and tang washer and run the spindle nut down finger tight, then rotate the hub back and forth then rock the hub side to side to make sure everything is seated properly. This will have had provided more room on the spindle, so run down the spindle nut with your fingers a bit more. The hub should spin freely, with a bit of brake lining...

  • What Could Cause Enlargement of Trailer Wheel Bolt Holes
    In order for the holes on your trailer wheels to become enlarged there would had to have been enough movement of the wheel on your hub's studs to allow the holes to be enlarged. The continuous friction from the wheel studs would wear on the holes in the wheel and enlarge them. Most likely the wheel was not secured to the hub with enough torque on the lug nuts or the wheel is intended for a hub that has different diameter studs. A bent spindle could cause uneven tire wear but not enlarged...

    From my research I found that the tires you have on your 2012 Keystone Raptor 377SE has 235/80-16 tires, and uses electric drum brakes. The first thing you will want to do is make sure your brake controller is adjusted properly. If you find it needs to be replaced I recommend the P3, part # 90195. This is one of our most popular because it is easy to install and operate. Since you are the original owner, you should have the brakes listed in the specifications for your trailer. I assume...

    We don't sell the hub/drum and the brake assembly as a kit, but I would be happy to make some recommendations if you could send me some more information. I'd need you to confirm the bolt pattern of your wheels (likely to be 8 on 6-1/2) and the reference number from your inner and outer wheel bearings. A 7K axle would typically use a # 25580 inner bearing and either an # LM67048 or a # 14125A outer bearing. A 7K axle would use a 12x2 inch brake assembly. I'd recommend using self adjusting...

  • What Is The Correct Oil Seal For A Dexter 9K Axle Pre-1989?
    The correct oil seal for the 9K axle pre-1989 is the Unitized Oil Seal # 10-63. It has a 2.250 inch inner diameter and a 3.376 inch outer diameter and is a dual action seal. The inner part stays fixed on the spindle and the outer casting rotates with the hub. This type of seal has less wear and tear to provide better leak protection.

  • Can Existing Grease Lube Hub Assembly be Replaced With Oil Bath Lubrication
    I would recommend that you install Trailer Hub & Drum Assembly, part # 8-219-9UC3, on your trailer. This hub is identical to the Trailer Hub & Drum Assembly, part # 8-219-4UC3, that you referenced except it is setup for oil bath bearings instead of grease bearing. These hubs have a 2-1/8 inch seal. The Oil Cap Kit, # RG04-270, is threaded and would only work on hubs that are threaded for screw in style caps. This would not work on the # 8-219-4UC3 as it takes press in style caps.

This assembly works with a 12 x 2 inch brake assembly like left hand electric brake assembly # 23-105, and with wheels that use 1/2 inch studs.

    Mobile home axles are designed for one time use and because of that we don't offer replacement hubs that will fit them since the spindles are usually very unique.

The Trailer Hub and Drum Assembly # 8-219-4UC3 that you referenced uses inner bearing number 25580, outer bearing number 14125A and is designed for 12 inch by 2 inch brake assemblies.
