Exploded View

Note: Some axles rated at 2,000 lbs require a different seal and bearings. Be sure that the bearings in the hub being replaced have L44649 stamped on them. If the bearings have L44643 stamped on them, use 34822BX trailer hub.


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"

Video Transcript for Dexter Trailer Hubs and Drums 8-91-05UC1 Review

Today we're going to take a quick look at the Dexter Axle Trailer Hub Assembly part number 8-91-05uc1. This idler hub is designed to fit 2,000 pound axles. It's got a 4 on 4 bolt pattern. If we're able to measure from the center of one lug, or one bolt, to the center of the other we get a measurement of 4 inches. Now included with the idler hub are the races, which are already pressed in inside the hub where they need to be. You'll also find the inner and outer bearings, in this case they're both number L44649; a grease seal, in this case it's 10-9; a grease cap that will go on the outside; and you'll also find the four conical lug nuts to go with our studs.

Now each of these idler hubs has a capacity itself of 1,250 pounds. When you pair it with the other you get a total of 2,500 which puts us at the range for a 2,000 pound axle. And that's it for a quick look at the Dexter Axle Trailer Hub Assembly part number 8-91-05uc1.

Purchase a pair of hubs and leaf springs plus assorted hardware for an old trailer restoration. The pricing was great and the quality and shipping were equally as good. The trailer is a 1999 Haulin which seen it's better days. Thanks to Etrailer, I was able to order everything I needed at one time. 102776

My old trailer hubs were made of cast iron and the cup portion was machined and impossible to keep smooth. The new hubs were machined for the cups and were already installed. Next time when I need to repack the hubs and inspect the bearings I will have the option of putting in new cups and cones making them new allover. Thanks for a great product at a great price!! Bill 152676


Comments

With almost 1500 miles on the trailer I have had no issues with the hubs or bearings. I did learn to keep a log of the miles on my trailer so I can keep track when to do maintenance on the bearings.

Comments

Working well. I am very pleased with the Dexter products. I have used enough axles, hubs, bearings over the years to know it is worth it to seek out quality name brand components like Dexter.

Product was exactly as advertised and quality was quite good. Fit was perfect to specs. Only had a couple issues with how it was packaged with the bearings, seals and caps taped to the outside of the hub. One bearing cage was dented. I was able to pry back with a screwdriver and it rolled fine. Also, one of the seals was dented on the OD. Doesn't seem to affect the fit. Both seemed to be dented prior to shipment because the shipping box was perfect. Overall 4/5 stars for the product! 214185

I am converting an old Coleman camper into a one room toy haler (model airplanes). The bearings in the wheels were shot. This pair of new hubs and bearings were cheaper then I could get the old hubs rebuilt locally. Also the old hubs had break drums I no longer needed. So the new hubs were lighter. Hubs look great and worked great. The new dust covers were not so great but my old caps worked. Shipping was unbelievable fast. All good stuff. 85935

Ordering was fast and easy, shipping was quick. The Dexter hub kits were a good replacement for the boat trailer I put them on but the grease seals included in the hub kit were not the size I needed. I knew it when ordering so I just ordered the correct size seals at that time. I've ordered from etrailer several times......never had an issue. Good customer service and support. 218047

by: Woody09/17/2012


The Hub Assembly for me was easier to buy new than rebuild as the original was thirty years old. The new hub was great and at a fair price. The only negative comment is that the new Dust Cover is not stong enough to hit with a rubber mallet without denting it- so I used my old ones which were made of heavier material. 54875

perfect fit I got all new parts the hub bearings races and lug nuts for $5.00 more than I paid for the 2 sets of bearings and nothing else my only complaint would be the hub cap didn't fit no matter what I did .great service I had to ask some questions and Jena was a real help great store and thank you Jena 178600

Good product, only thing keeping it from a 5 star review is that one hub has just a hair too much clearance for the O-ring, yes I've tried multiple different rings, that allows a small bit of grease to ooze out. The opposite hub has no such issue. Other than that can't beat it for the money. 407355

Ask the Experts about this Dexter Axle Trailer Hubs and Drums
Do you have a question about this Trailer Hubs and Drum?


  • Does a Trailer Wheel Center Hole and a Hub Bore have to Match
  • The expert answer you have referenced is correct. A wheel that secures to the hub using bolts instead of lug nuts actually centers on the hub so the pilot hole of the wheel has to be exact. If it is too large the wheel can easily be off center and lead to all sorts of problems. Hub # 8-91-05UC1 has a center bore outer diameter of approximately 2.4375 inches; very close to 2.5 inches but not quite. If you use this hub and the wheels you are using have a pilot hole that is larger, it will...

  • Availability of Trailer Hub That is 4 Inches Long, Has 1-1/16 Inch Bearings, 4 on 4 Bolt Pattern

With those numbers, we can find which hubs would be a correct fit. I am including a link to a video that will show you how to remove, inspect, and reinstall trailer bearings, races, and seals. I have the Dexter Trailer Hub Assembly, part # 8-91-05UC1 which has a 4 on 4 bolt pattern. It uses the TruRyde Bearing,...

  • Replacement Bearings and Seals for a Dexter Hub with 8-91A Stamped on Back
  • If the spindle that was on your trailer axle previously had 8-91A stamped on the back of it your spindle should require inner and outer bearings of # L44649 like you used. The part # 8-91-05UC1 that you referenced would be an exact replacement. Grease seal # 10-9 is the correct replacement seal also. It has an inner diameter of 1.5 inch and an outer diameter of 1.987. The double lip version of this that is sold in pairs is our part # RG06-020. # 10-9 is sold individually. Double...

  • Do Trailer Hub Assemblies Come Assembled, Greased and Ready for Installation
  • The Trailer Hub Assembly - 2,000 lbs Axles - 4 on 4, item # 8-91-05UC1, does not come assembled. You will need to work grease into the bearings and hub and clean the spindle on your trailer before installation. You will also have to install the seal in the back side of the hub once the inner bearing is greased and installed. I like to use a small piece of 2X4 and lay the seal as straight as possible on the hub and tap the 2X4 with a hammer spinning it as I go around the seal, until it is...

I have included a picture that shows what measurements are needed. The difference between bearing L44649 and L44643 is only 0.063 inches but for bearings, it is critical to get the correct size. This is also why you cannot measure using a ruler or tape measure. It has to be dial or digital calipers.

  • Replacement Hub Assembly For Utility Trailer
  • We do have the parts you need for your trailer. I recommend the trailer hub assembly, part # 8-91-05UC1. This is a hub assembly that comes with bearings, races, seals, and the grease cap. The bearings included with the assembly will work fine. The seals in the assembly will not work for your spindles as the inner diameter is too large, but we do have a solution. These are 4 on 4 hubs and include the bolts on the hub and also include the lug nuts. You will need to order part # RG06-010...

  • Hub, Rim and Spindle Recommendation for 13 inch Wheel with 4 on 4 inch Bolt Pattern
  • For a hub with a 4 on 4 inch bolt pattern that can fit 13 inch wheels with the pilot diameter of 2.5 inches the part # 8-91-05UC1 would be what you would need. For a white rim to fit this the part # AM20222DX would work well. Then for a spindle for the hub to fit on you would want the part # R104BTREZ.

  • Trailer Hub Recommendation to Replace Hub with L44649 Inner and Outer Bearings
  • For a hub that fits your spindle we have the part # 8-91-05UC1. This hub uses the same bearings as what you currently have of L44649 and has the same 4 on 4 inch bolt pattern you have as well. This cap that comes with this hub does not have the EZ lube opening either.

  • Looking for Galvanized 4 Lug Trailer Hub Compatible w/ # T20BTR-6048 Dexter Trailer Axle
  • The # T20BTR-6048 Dexter 2K axle you referred to is compatible with a L44649 inner and outer wheel bearing. The # 8-91-05UC1 hub assembly has a 4-on-4 bolt pattern and uses the L44649 bearings. 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. Keep in mind, if you switched to the 5 lug hub, you'd need to swap out your existing wheels for wheels with a 5-on-4-1/2 inch...

  • Replacment Trailer Hub Recommendation for Hub Marked 8-259
  • We do carry the Dexter hub part # 8-259-5UC1-EZ which matches the first part of the part number you mentioned. This is a 5 lug hub though so for a 4 lug hub version of the same hub you would want the # 8-91-05UC1.

  • Will Bearings from the 1970s Fit Current Trailer Hub Assemblies
  • There have been changes here and there in the trailer industry since the 1970s. To be sure your old bearings will fit the newer components, like the Trailer Hub Assembly, # 8-91-05UC1, that you referenced, you will need to check the numbers on them. This drum accepts the following: Bearings (L44649 Inner/Outer), Races, Cap (1.986 inch outside diameter). The inner bearing dimension is 1.063 inches and the inner seal dimension is 1.5 inches. If your existing components match these...

  • Comparison of Dexter and etrailer.com Idler Hubs for 2,000 Pound Axles
  • The two trailer hubs # AKIHUB-440-2-2K from etrailer and # 8-91-05UC1 from Dexter are basically the same product from two different manufacturers. They're both hubs for 2,000 pounds axles with 4 on 4 bolt patterns and use the same # L44649 inner and outer bearings. The Dexter hub does have a little higher weight capacity at 1,250 pounds vs. the 1,000 pounds of the etrailer hub. However, the price difference is mainly determined from our relationships with the manufacturers and therefore...
