Trailer hub assembly includes lug nuts, inner bearing (L44643) and race, outer bearing (L44643) and race, grease cap and grease seal. Fits 2,000-lb axles.
Dexter 8-91A should be stamped on back of hub
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 L44643 stamped on them. If the bearings have L44649 stamped on them, use 8-91-05UC1 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.
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.)
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.)
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.

Today we're going to review part number 34822BX this is a Dexter Trailer Hub Assembly with a 4 on 4 bolt pattern for 2000-lb axles. This trailer hub assembly will include four of the 1/2-inch cone seat lug nuts. It will include the inner and outer bearing which will be the same part number that is L44643. It will include the grease cap and the grease seal which is part number 34823. Now the bearing races will also be included and they are already installed into the hub assembly. Here is the outer bearing race right there and if we go to the back you'll see the inner bearing race right in there.
Most all our hub assemblies will come pre installed with the bearing races. Now this application will fit on the 2000-lb axles. Now there is a note you want to make sure that some axles that are rated at 2000 lbs will require a different seal and bearing. Be sure that the bearings in the hub that you're replacing have the L44643 stamped on them. If it does use a bearing that will have L44649 stamped on them then you will need to use a totally different trailer hub which would be the part number 8-91-05UC1.
The capacity on this hub assembly is 1250 lbs. So if you use this or pair this with a hub assembly of the same thing on the other side of the axle would give you a max of 2500 lbs. Now we do mention this is a bolt pattern of 4 on 4 and basically on a bolt pattern that would normally even number of lugs, which in this case would be four. You could just measure directly across from the center of one stud to the center of the other. But in this case because this hub sticks up or protrudes up some it's going to be hard to actually get a correct measurement.
So what you can also do is just measure from the center of one stud to the center of the other and on a 4 on 4-inch bolt pattern that would measure up 2-7/8 inches. That will determine that this is a 4 on 4-inch bolt pattern. Now this hub assembly that uses the L44643 inner and outer bearing will be stamped on the back. It's stamped in it. It might be hard to see but it is stamped 8-91A.
And that should do it for a review on part number 34822BX.
Average Customer Rating: 4.7 out of 5 stars (77 Customer Reviews)Trailer hub assembly includes lug nuts, inner bearing (L44643) and race, outer bearing (L44643) and race, grease cap and grease seal. Fits 2,000-lb axles.
Hub itself is better quality than the original hub I replaced on the trailer. I am extremely happy with the hub and it rates excellent. However the bearings, grease seal and cap are very cheap parts made in china. They rate poor in my book. What do you expect from a $3.25 China bearing? I installed the dry bearing into the race to check fit and it had flat spots and wobbled as I spun the bearing. All four bearings in 2 kits all had the same problem. I purchased 4 SKS bearings from local parts store @ about $8.50 each. They spin perfectly in the race. I upgraded the grease seal to a double lip instead of the single lip in the kit. I installed the cap with a rubber mallet and block of wood but they are thin and dented badly before they seated. They may work if you had a large socket or a collar that fit around the lip but if you contact the center of the cap in any way it will dent badly. I will replace those with a bearing buddy or better quality cap someday. What is the point of an assembly if you have to replace the substandard parts within it? Cheap bearing and single lip grease seal may work fine with light duty local hauling but I plan to run several hundred miles and believe I need better bearings and seals to handle the long miles without trouble. I did a 220 mile test trip yesterday and the hubs did not build any heat at all after the parts upgrades. I am not telling people to not buy this hub because the hub is excelent quality but I am telling people to plan on upgrading the bearings, seals and caps if they need a top quality trouble free assembly. Now let me tell you the good news. The price of the assmebly from Etrailer is good enough that even after the upgrades, the price is better than other hubs I found locally or on the web. Buy it but upgade it for the best possible hub assembly. I plan to purchase one more assembly from etailer as a back up. I do not want to be several hundred miles from home without a replacement I can install on the road if needed. Best $35 "insurance" I ever spent. 79060

The actual hub is of exceptional quality as it is a cast hub and is a giant improvement over the tubular steel w/welded on lug plate I took off. Was not impressed with the fact that the MFG did not pack these in a cardboard box and just wrapped all the parts around the hub with tape, paint job on the hub was not the greatest but did not matter to me as I repainted it a different color to compliment my new wheels, the dust cap is flimsy and easy to dent unless you cut a notch the width of a hacksaw blade 1/2 way to the stop ring but again did not matter to me for anything but to keep the paint off the bearing race as I used my old bearing buddies. The hub is of automotive quality and I give it a 10 for quality, cost, fit and my hat's off to the service at Etrailer. 130887

I've attached some pics of the smoker I'm building using the hubs and spindles I purchased from you. Thanks for the quick shipping. Hubs and spindles fit perfect. 121889

I needed to replace the hubs on my jon boat trailer. Etrailer had the exact hubs I needed, in stock. The description in their shopping cart made it easy to order the right part. They shipped promptly and I received the order within a few days. The hubs were well packed. Their quality is first rate. They even included bearings, seals, races which came installed in the hubs saving me some time (thank you!), and lug nuts at a price that was less than the bearings and seals alone were going to cost me at a local auto supply store. A diagram on their web site showed me how to install the innards and I installed both hubs on my trailer in a little over an hour. Thanks again, Etrailer. 15993

The staff at e-trailer was very helpful and informative regarding their product. I learned several things about trailer equipment, in general from the staff, as well. I especially appreciated their efforts to assist me in solving a problem that arose several weeks after I had received the tires and wheels that I had ordered. The fix was to replace the existing hubs (4.5 inches) with new ones that were the standard 4.0 inch hubs. 93773

Great response time and follow-up. I ordered this hub assembly on a Friday and received it on Tuesday. Everything needed was in the package to replace a damaged hub and bearings on a small trailer a friend and I are rebuilding. I did find damage to one of the bearings when I received it. I called etrailer, spoke to Ashley and another bearing was shipped that day. If I need any other trailer parts etrailer will get my business. 30630

First Time User I had ordered a utility trailer wheel hub assy, ( I thought). It arrived quicker than I had paid for, but it wasn't an assemlby. I may not have read the smaller print on the product page when I had ordered the hub, which may be why I had expected all the parts to have been assembled upon receipt. Great job on the illustrated installation instructions!! Over all, I am very pleased with the service! 4843
Phone rep was great with technical information. When asked, told me ahead of time that product was made in China. Product arrived in god time and was as described. I was disappointed that the bearings cover is so thin and difficult to place without denting. It would be helpful if a cotter pin was included. It would also be nice it retailer had a source of USA made bearings to offer. 146543

I have a small 1200 lb Harbor Freight Tool trailer. The original bearings blew out and I had to replace the bearings, seal and hub. Went to our local Colorado Springs bearing supply house. I bought the hub, seal, bearings and cap for less that what they charged for one bearing, bought tires too - for less and better quality than what Discount Tire charged. Will be coming back 45225
Your processing, delivery and communication were very good. I would have given an excellent rating except the bearing seal was received with a slight bend and nick in it. In the interest of time, I am removing the seal from the old hub and using it. I recently ordered that seal from you and installed it before realizing there was another problem in the old hub. Thanks.....Jim 44274
The replacement hub assembly shipped very quickly. This was the first time I tried rebuilding a hub but the dimensions were spot on and it was very easy to assemble (I did watch some videos on YouTube). It seems to be a good replacement. The only complaint I have is that the grease cap came bent so it was a little tricky to round it out just right to fit the hub. 162357

Original wheel bearings on the trailer finally give up after 30 years so went shopping at etrailer again. I received a replacement hub and bearings at a very competitive price and in a short time. It took 4 days via ground. I’m happy. I’ve purchased 4 hitches for four cars plus accessories through etrailer and I’m very satisfied with the product and service. 9056

Great product and shipped promptly. The difference between these hubs and my old ones is HUGE, really glad I decided to replace the whole assembly. Remember, this is just the hub assembly and bearings, so if you're replacing existing hubs, hold onto your castle nut and cotter pin. The dust caps are also a real tight fit so be patient when putting them on. 37571

Building a Custom Double Kayak Trailer.........res for best prices.....E-Trailer has the prices and inventory I was looking for! I ordered a whole list of parts in two separate orders. Both orders were processed and shipped immediately and arrived well packaged and on time! Site is easy to navigate! Highly recommend for a new-build or repairs! 8336

Fit and finish are better than the original hub. Nice to have races pre-installed. Coating on the stud threads made it a little tough to thread the nuts by hand, but lug wrench did the job without much hassle. Casting had a minor shortage of material on the outside diameter of the outer bearing case, but the inside diameter was completely round. 82083

The purchaser, me, ordered the incorrect hub and it is being returned to etrailer. I called etrailer while the order was in transit to let them know that I had discovered my mistake and they were very understanding to my situation and even provided specific return instructions by a follow up e-mail. This is a great organization to do business with. 18701

Great price, quick delivery, perfect fit. I installed it with no problem (I used by old bearings because they were still good). Used my old cover because the new one was dented. So far it has worked very well. I recommend this part and etrailer for the price, technical help already on their website, and quick shipping. 145346
Ordered a set of these for my PWC trailer. Fit great but I should have ordered some codder pins. Don't forget those when replacing your bearings. Some of the paint came off, but no big deal. Bearings looked great and roll super smooth now. Order some bearing buddy's with this too for any watercraft trailer. BB1980A 146338

This was an exact fit for what I needed; very heavy duty. I was able to assemble and install the items with ease, especially after viewing their product installation video. E-trailer is such a nice company to deal with anyway. Their personal, friendly -- and fast -- service are all reasons why I love shopping with them. 141425

the cap was bent beyond repair, I'm using this for my harbor freight 1195 lb trailer as a spare. the harbor freight trailers use 25 mm tapered bearings this one comes with 1" bearings. so I changed the bearings to the correct size and it will work great for my purposes. 122500

I was very pleased with the prompt delivery. My trailer was down and I desperately needed the two hubs to reassemble it and get my equipment back from the small engine guy. My order was processed in hours and arrived in just five days. I highly recommend etrailer. 54391
by: Mark F03/30/2012
Everything was perfect, except for the dust cover. I had a time getting it on and damaged it in the process. It seemed just a smidgen to large. Shipping was excellent and arrived a day early! The price was excellent also! I will be ordering from etrailer again. 35703

Very satisfied with my transaction with etrailer. Item arrived as per description. Good packaging and product was expedited for free! Constant email communication from Kevin J, George J, and Tamara W. I would purchase from etrailer.com again! THANKY YOU! 120221
The hubs that I received fit the trailer without any effort . The bearings were adjusted and greased . Now the only thing that is left to do is use the trailer and hope the hub and bearings last forever . Thanks Ken 24160
Heather was very helpful when ordering this part for my old boat trailer. She walked me thru the different measurements necessary to get the right hub. It fit the first time and I was back out on the boat cruising this weekend. 50688
The lug nuts are a nonstandard size, which is annoying. The only real problem is the dust caps are super thin and showed up bent and would not fit. The bearings seem cheap, I will probably replace them with Timken ones. 156363
by: Dan Simpson03/30/2012
Had an older boat trailer and the rear seal would not stay in place and allowed water to enter the hub. This replacement hub was a perfect fit and should solve my problem. Ordering was easy, shipment was fast. Thanks 35611
by: Fonzy G04/15/2014
The part I got was exactly the right part I order. This place is the best place to get for your trailer, I'll be purchasing more from this place. The price and shipping were very very reasonable. Thank you so much. 125272

eTrailer's customer service is 1st rate. I appreciated the follow-up. The new wheel hub is exactly what I needed and it is already installed. Was not too impressed with the bearings from China though. 15841
by: jim s08/20/2014
everthing went fine until i tried to install the dust caps. they were flimsy compared to the ones is was replacing, after trying for awhile i used the old ones. it could have been my inexperience. 147763

It arrived quickly and was very well made. I was replacing hubs and bearings from a Chinese trailer and it was pretty obvious how much better made this hub and bearings were. 19343
nice hub great price i liked the hub it was new looks strong smooth design i just wish it was a galvanized hub i didnt find any on the site but this one will do the job 5495
I've built a few small trailers and carts with these hubs and spindles, and they work great! Etrailer.com has the best prices I've found so far. 22395
