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.

No problem with this hub since replacement.



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.

  • 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...

For 1/2" studs with a grease cap you'll want # 8-219-4UC3, For 1/2" studs with an E-Z lube cap you'll want # 8-219-4UC3-EZ, For 1/2" studs with an oil bath hub you'll want # 8-219-9UC3, For 9/16" studs with a grease cap you'll want # AKHD-865-7-1-K, For...

  • 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.

    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...

  • Lug Nuts Shearing off Hub and Drum of 7,000 lb Dexter Axle
    I can only make a guess and can't know for certain, but generally speaking, the two main reasons that lug nuts shear off is that they are overtightened - though you can rule that out if you are sure they were torqued to the manufacturer's specs - or that your wheels have elongated, wider holes. This would make the wheel have excessive movement on the lug nut and cause enough vibration for it to shear off. If you need to replace the hub and drum on your 7,000 lb Dexter axle you can use...

  • 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.
