Determining Bolt Pattern

Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).

Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug

2a. For even lug counts (4-lug, 6-lug, 8-lug)

Measure from the center of one lug hole directly across to the center of the hole opposite it.

Center to Center
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"

2b. For odd lug counts (5-lug)

Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

These are great hubs for your boat/jet ski trailer. Nice to know they won't rust like my old ones did. Also a nice purchase to not have to install the races. Very pleased. thanks etrailer!

I live in Washington and fish in Puget Sound. I have a boat that I use in salt water. I launch the boat several times a week in the summer season. The trailer hubs are constantly in and out of the salt water. I replace the bearings and sometimes the hubs every couple of years. This is the first time that I have tried galvanized hubs. I have high hopes that they last longer than non-galvanized hubs.
by:
Hubs were easy to assemble and install. etrailer provides detailed instructions and video links as well. Customer service is outstanding. Hubs have performed without issues

Paula S have me the part number for the seals and race so I could get them locally. I’m driving to Weast coast with this trailer tomorrow so no time to wait for etrailer to ship replacement parts

I live in California and my shipment was sent to Boston Mass. The rep told me that when they find it in Boston , they would have it sent from there to California, which would take another five days. I needed it in three days as they promised not in eight. Horrible that customer service thought this was adequate.
by:
Sarah was a great help I almost ordered the wrong one so thank you !!
by:
Everything was in the box except the bearings. Customer service is shipping the bearings. Just inconvenient.
by:
I have not yet installed them but have unpacked and took measurements. The only issue I have is the grease seal ID is .25 to large but that is most likely my fault during the order, I have the right size grease seals coming.
The hub is solid and the bearings fit real nice, no slop. This is for a boat trailer which goes back and forth to a very rural camp so it gets bounced around a lot, time will tell how these hold up. The original hub and bearings are ok and will be my field spare should I need it, slip one hub off and the other on, tighten and go. I like the stud with lug nut to hold the rim rather than original bolt into the hub, easier for tire mounting and I can put a locking lug nut on as well, personal preference.
This seemed to be the most cost effective means, all one package, just watch the size of the individual parts to make sure you get all the parts the correct size.
etrailer.com packed the parts well, nothing flopping around or damaged.

No complaints, now the dirty part, replacing the old with new.

Still on the trailer and working out well. I have put some hard miles on them and they seem to be holding up. Just shot some grease in them before the next trip.

by:
This place is a joke. Called to place order, the help was fine, but I paid for fast shipping because I needed it and a hurry and my parts didn’t even ship out till the day they were supposed to arrive.
by:
All parts ordered, 2 wheel hubs and bearings, 2 galvanized rims and bearing buddies all arrived in good shape. All parts mounted and work as expected. Etrailer.com is an excellent place to buy parts for a reasonable price.

Thanks Tommy! Whenever you're ready for your next project, we will be here and happy to help!

was only going to replace the bearings and races but replacing the entire hub assembly was so much easier and not that much more cash. Packed the bearings, banged on the seals, bolted them on..done! And it was all galvenized to boot.

  • Recommended Replacement for Dexter 8-259 Idler Hub

  • Replacement Hub Assembly For 2003 EZLoader 3-EZB 12-14 Boat Trailer
    I recommend the Galvanized Dexter Trailer Idler Hub # 8-259-50. With this you will need 2 Trailer Hub Bearings # L44649 and a Grease Seal # 34823 per hub. The races are already installed on the hub and you can reuse your Bearing Buddy Bearing Protectors # BB1980A unless they are damaged and in need of replacement. A new Cotter Pin # 165649 and Lug Nuts # CE11051 are also available individually if they also need replaced. Currently we do not have these parts available as a complete greased...

  • How to Select Correct Replacement Hubs for Old Trailer
    The things you need to confirm to choose a replacement hub for your old trailer are the axle weight rating (usually noted on a sticker or plate on the axle itself), the wheel bolt pattern and the numbers of the bearings used in the existing hub. The linked article on bolt patterns will make it easy to confirm which you have. You need to confirm the bearings used to ensure that the new hub will fit properly on your spindles. The linked photo shows the usual location and appearance of bearing...

  • Hub and Spindle that Can Fit 10 inch Wheel with 5 on 4-1/2 inch Bolt Pattern
    For a hub that is compatible with a 10 inch wheel and has a 5 on 4-1/2 inch bolt pattern you would want the Dexter part # 8-259-50 and then for a spindle part # TRU97FR .

  • 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.

  • 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.

The hub we offer is designed for 2,000 and 2,200 lb axles and will work with wheels that range from 8 to 12 inch diameter. This part number is # 8-259-50. The bolt pattern for this hub is 5 on 4-1/2. The bearings you can use for this hub are either part # L44643 or part # L44649. You will need to use a precision instrument like a digital caliper to measure the spindle where the bearings are used.

  • 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.

  • Trailer Hub Replacement with Bearings # L44643 and # L44649
    Based on the bearings you mentioned the correct hub you'd need is the part # 8-259-50. This does not come with bearings though so you'd need to also order the part # L44643 and # L44649 as well as the grease seal # 10-9.

  • How to Measure to Find Correct Grease Seal for Hub With Inner Bearing L44649 & Outer Bearing L44643
    I was unable to locate any hub with those numbers, so in order to find the correct grease seal, what you'll need to do is measure. To get the measurement, use digital caliper and measure your spindle to the thousandths of an inch where the grease seal rides like in the accompanying photo. For a hub with inner bearing # L44649 and outer bearing # L44643 and a 5 on 4-1/2" bolt pattern, you will likely need the Dexter Trailer Idler Hub for 2,000-lb and 2,200-lb Axles # 8-259-50.

  • 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...

  • Will Dexter Trailer Hub # 8-259-50 Fit 1-1/4 Inch Spindle on Trailer
    If you have a 1-1/4 spindle like the TryuRyde # TRU94FR, then the Dexter Trailer Hub # 8-259-50 that you referenced will fit perfectly. With this in mind, I do recommend verifying the bearing numbers for your current hubs or taking a few measurements along the spindle where the bearings sit. You will want to use a digital caliper like # PTW80157, as the measurements need to be exact. I have attached an image to assist. This Dexter Trailer Hub uses the # L44643 or # L44649 inner and outer...

  • 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.
