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"

by:

These Dexter trailer hub and drum assemblies fit perfectly, just like the OEM one's I am replacing. Original brakes lasted over 10 years and 26K miles (with life still left on the brake shoes)!



by:

Promptly shipped and received. Minor problem, the bearings, nuts, dust cover and seal were all just thrown loose in the box with the hub resulting in the seal being bent and unuseable. No big deal. Otherwise great service.

Thanks etrailer.

what drum and hub assy do i need to convert my house tralier axles to use regular tires and wheels? im having trouble finding tires for them. bearing, outside 1.25, inside 1.75, 2 brake drum, 5 or 6 holes wheel.

Patrick B.

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.


by:

Easy lookup, detailed information, and lightning fast processing and shipping made this transaction very satisfying. All this, combined with great prices guarantees my future purchases. Thank you!

  • Is Dexter Trailer Hub # 8-219-4UC3 Sold Individually or in Pairs
    The Dexter trailer hub and drum # 8-219-4UC3 that you referenced is sold individually so if you needed a pair you'd need to order two of them.

  • Correct Hubs/Drums with Modern Bolt Pattern for Trailer with 1-3/4" Inner and 1-1/4" Outer Bearing
    Yes, we have options for both a 6 on 5-1/2" bolt pattern using the Dexter Trailer Hub and Drum Assembly part # 8-201-5UC3 and an 8 on 6-1/2" bolt pattern using the Dexter Trailer Hub and Drum Assembly part # 8-219-4UC3. These both use a 2-1/8" grease seal as well.

  • 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...

    The Dexter Trailer Hub and Drum Assembly # 8-219-4UC3 comes with 1/2" wheel studs. For extra wheel studs you need the Trailer Hub Wheel Stud # 7-122. If you need extra wheel lug nuts you can use the # CE11051.

  • Availability of Extra Nuts for 1/2" Wheel Studs on Dexter Hub and Drum Assembly
    For extra nuts that will fit the wheel studs on the # 8-219-4UC3 you can use the CE Smith Trailer Wheel Lug Nut # CE11051. These will fit the 1/2" wheel studs on the hub and drum assembly.

  • Bearing Buddy Fit For Dexter Trailer Hub 8-219
    Yes we do; for a Dexter 8-219 trailer hub such as the Dexter Trailer Hub and Drum Assembly for 5,200-lb to 7,000-lb Axles # 8-219-4UC3 the Bearing Buddy that fits is the Bearing Buddy Bearing Protectors - Model 2717SS - Stainless Steel (Pair) # BB2717SS.

  • 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.

  • Does Hub and Drum 8-219-4UC3 Come Individually or in a Pair
    Hub and drums do come individually, so you will need to order a quantity of two of the Dexter Trailer Hub and Drum Assembly for 5,200-lb to 7,000-lb Axles # 8-219-4UC3. For use with this hub you will need 12" x 2" electric brake assemblies, which do come in a pair, the Electric Trailer Brake Kit - Left and Right Hand Assemblies # AKEBRK-7-SA. You will also need the Mounting Bolts and Hardware for 12" Brake Assemblies # BRKH12. I have added links to a video review and installation of...

  • 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...

  • How to Lift a 1971 Airstream Sovereign Trailer
    The best way to identify a trailer axle is to look on the center for a tag or sticker with the serial number. If there is none present then there aren't really many other options save for the trailer manufacturer having a record of this. In order to lift the trailer I recommend you measure the distance between the two mounting holes on both the axle and frame. The top axle mounting holes will need to be spaced 9" apart on center and the frame mounting holes will need to be spaced 9.5"...

    The Dexter Trailer Hub and Drum Assembly # 8-219-4UC3 fits a standard #42 Spindle # TRU57FR. While the Dexter Trailer Hub and Drum Assembly # 8-219-4UC3-EZ fits a E-Z Lube #42 Spindle # TRU37FR. You will need to select the appropriate assembly based on your 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.

  • Replacement Hubs And Brakes For A Sure Trac Trailer With Lippert 7,000 lb Axles
    Generally the 7,000 lb Lippert axles are going to use standard sizing. With the brakes being the 12" x 2" with a 5 bolt backing plate, and the hubs being an 8 lug, and using the standard 1.25" Outer and 1.75" Inner bearing. While I do not know exactly what model axle you have, or when it was made, it should use this same sizing. Since trailers are not completely standardized, we do suggest that you measure to confirm fitment prior to ordering. Provided it is standard, you can use the following...

  • Determining the Right Brake Assembly and Hub Drum H and H Cargo Trailer
    To get the correct brake assembly, you need to know the axle weight capacity, the backing plate bolt pattern, and the dimension of the drum. A 7000 lb axle would typically use a 12 x 2 assembly with a 5 bolt backing plate. Parts # 23-464 and # 23-465 are a good example. For replacement drums, we would need to know the wheel bolt pattern (which is typically 8 on 6-1/2) and the reference numbers off of the existing wheel bearings. Part # 8-219-4UC3 would be a typical hub and drum for a 7000...

  • What Size Wheel Center Hole Will Fit on Trailer Hub 8-219-4UC3
    The pilot hole on a wheel would have to be 4.75 inches or larger. 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.

  • Replacement Hub and Drum Assembly for Dexter 008-219-04
    You are correct, the # 8-219-4UC3 matches your existing hub and drum assembly. I'm assuming you're referencing the difference in the grease cap when you say the grease is different. This has a standard grease cap, but you can use your existing E-Z lube grease caps in place of the caps that come with this assembly. If you want new ones you can use the # RG04-080. The grease cap and plug is the only difference between a regular and E-Z lube hub and drum assembly.

  • Trailer Wheel Pilot Hole Diameter is Too Small for New Hub and Drum Assemblies
    If the pilot hole on the wheel was larger than 4-3/4 inches, and the wheel is center on the hub using the lug nut rather than wheel bolts, it would not matter. But since the wheel pilot hole is smaller, you will not be able to use the hubs you purchased without also replacing the wheels. I went out to the warehouse and measured a Trailer Hub and Drum Assembly, # 42866UC3, to determine the diameter of the center portion that goes through the pilot hole of the wheel. Using some digital dial...

  • 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...

  • Is Loctite Required for RV Wheel Lug Nuts
    In regards to trailer wheels and lug nuts, you should not be using any sort of thread locking compound such as Loctite. It's not needed and would make getting the wheels off for maintenance very troublesome. Instead, you would simply need to torque the lug nuts to the wheel specifications using a torque wrench like the 1/2" Drive Torque Wrench part # PTW3001C. I have attached for you below a wheel lug nut torque chart.

  • Replacement Bearings and Seals for Dexter Axle 8-219 Hub and Drum Assembly
    Thank you for all of that information, it really helps boil down what you're needing. If you're wanting to replace the entire hub and drum assembly then you can use part # 8-219-4UC3 for a standard spindle or part # 8-219-4UC3-EZ if you have an EZ Lube spindle. These come with grease seals for a 2-1/8" diameter spindle so if you have a grease seal that uses the 2-1/4" inner diameter you'll need to swap out the grease seal with part # RG06-070 so that it fits properly.

  • 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.

  • Hub and Drum Assembly Needed for a 1979 Featherlite Horse Trailer with 6000lb Axles
    It sounds as if you will need the trailer hub and drum assembly # 42866UC3, which has an 8 on 6-1/2 bolt pattern and uses the # 25580 inner bearing (1.75 inch inner diameter) and # 14125A outer bearing (1.25 inch inner diameter). 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.
