  • Replacement Axle, Hubs, Brakes, and Tires for Older Trailer With Dexter 22834 Hub
    Based on the axle and bearing measurements it looks like your trailer was using a Dexter 22834 hub. The Outer Bearing # 1779 has an ID of .938" and the Inner Bearing # 2788 has an ID of 1.50". The outer bearing is slightly off but that may be due to a measuring error. That would also mean you have 5,200 lb axles on the trailer. This is an obsolete assembly so you will need to replace the entire axle. For a replacement you can use the # e55SR. This will stick out an extra 3/4" on either...

  • What Size Axle Does a #84 Spindle Fit
    A true 1 inch spindle is a BT8 spindle, like # TRU94FR. The next closest one would be the BTR spindle which is commonly referred to as a 1-1/16 inch spindle, like # TRU44FR and is more common than the BT8. Both of these are typically used with 2,000 lb axles. A #84 spindle, like # TRU24FR or # TRU47FR is bigger and is used for 3,500 lb axles. Common sizes for these are 2-3/8 inch round axle, 3 inch round axle, and 2 inch square axle. I have linked a helpful page that shows the different...

  • Availability of 1 Inch Diameter Trailer Spindle To Fit on 1.25 Square Axle
    The two spindles that I have to fit a square axle are designed with a square stub diameter of 1.50 inches. The TruRyde BT8 Spindle 1-1/2" Square # TRU97FR, you have referenced is for 2,000-lb axles and the TruRyde Spindle, part # TRU47FR, is for 3,500-lb axles. They use different bearings and seals. I am including a link to a product page that will list the dimensions on the trailer spindles we have available. Square axles can be tough to determine capacity. Often times the same spindle...

  • Where to Measure on Trailer Spindles to Determine Replacement Hubs
    You will need to measure the diameter of the spindles where the seal and bearings ride. Check out the picture I attached that shows where this is. You will need an exact measurement so either a digital or dial caliper will be needed. To pick out the correct hubs you will also need to determine the bolt pattern of the hubs you currently have so that the new ones will be compatible with your current hubs. I attached an FAQ on how to determine this. If you get back to me with that information...

  • Removing and Replacing Trailer Spindles
    To replace a spindle, the old one would need to be cut off, and the new one welded into place. This is NOT a job for the do-it-yourselfer. The new spindle must be absolutely square with the axle in order to prevent premature tire wear and wheel tracking problems. I would recommend finding a welder who is experienced with trailer axles. Your local RV dealer or repair facility could probably refer you. In many cases, it's less expensive to simply replace the trailer axle itself. We offer...

  • Galvanized Idler Hub That Fits Square #84 Spindle
    Let's start with the spindle and hub you asked about, and they are indeed compatible. Reason why is this spindle accepts hubs with inner bearing L68149 and outer bearing L44649, which is exactly what the Easy Grease hub you mentioned uses, so the two will work together: - Square #84 Spindle for 3,500-lb Trailer Axles # TRU47FR - Easy Grease Trailer Idler Hub Assembly for 3.5K Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-35-G-EZ-K And as for the hanger kit and leaf springs you mentioned,...

  • How to Determine Hub and Spindle Size
    The spindle dimensions are as follows: A is the mounting dimension, B is the seal dimension, C is the inner bearing surface, D is the outer bearing surface and E is the diameter of the threaded portion of the spindle for spindle nut selection. Say you need a spindle and hub for a wheel with 5 on 4-1/2 inch bolt pattern and an axle that is 3500 lbs. For a single axle trailer you can use two of either the item # TRU64FR, if your axle is round or item # TRU47FR if your axle is square. Then...

  • Replacement Hub Needed For Koyo Bearings L44648 And LM48548
    Hey Ron, It unfortunately looks like we don't offer a hub that's compatible with the # LM48548 and I couldn't find an alternative bearing that would match that same inner diameter to fit the spindle. The only option we could offer at this point would be to have a shop weld on a new more commonly-sized spindle to your current axle or replace the axle entirely. Typically, the cost of replacing the spindle outweighs the cost of a new axle so I'd explore both options. To replace the axle...

  • Axle Kit for Fabricated Ice House Trailer
    All of our trailer spindles are shown on the linked page, but none of these has a stub end to fit 2 x 3-inch tubing. All are either round like # TRU74FR or square like # TRU47FR. For a fabrication project like yours a better solution may be a bolt-on axle-less suspension kit from Timbren, such as # A12RS440, which is rated for 1200-lbs and which includes idler hubs with the 4-on-4-inch bolt pattern. Bearings, races and seals are included with hub. All Timbren axle-less kits and beam axle...

  • How to Pick Out Replacement Hubs for a Boat Trailer
    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. Since the figure you came up with doesn't match any of the 5-bolt bolt patterns I am going to need to to recheck your bolt pattern.

  • Help Identifying And Replacing Hubs And Spindles On An Old Trailer
    Hey Mark, thanks for the pictures. That is a pretty interesting trailer. I can't say I have seen anything like that before on a trailer with a single leaf spring spanning the whole axle like that. It almost looks homemade or like someone used an axle or transverse leaf spring from an old car. Anyways, the hub appears to be a 4 lug idler hub, but I am afraid I can't give you any more specifics beyond that just by looking at a picture. If you are looking to replace the spindle and hub, your...

  • How to Determine if Trailer has 84 Spindle to Pick Out Replacement
    In order to verify the spindle dimensions so that you can pick out the correct hub/drum you have to get exact dimensions. For that you need to use a digital caliper like part # PTW80157. For how old your trailer is this is especially important as the standard spindles sizes have changed since 1969. An 84 spindle would measure 1.06 where the outer bearing rides, 1.38 where the inner bearing rides, and 1.73 where the seal rides. For a hub with a 6 on 5-1/2 inch bolt pattern that would fit...

  • Why Would A Trailer Tire Sit Crooked After Towing
    Hey Allen, Bearing fitment is precise down to ten thousandth of an inch so it you have the incorrect bearings installed in your hub there will be play on the spindle, which can cause the bearings to overheat and either explode out inside the hub or melt to the spindle. Play in the bearings will also cause the wheel to sit crooked but so can a bent axle. I would scrap what you have and start fresh by measuring the spindle with a digital caliper # PTW80157 at points B, C, and D on the...

  • How to Measure for a Replacement Hub
    I am sorry Nicole but I can not find any information on the d-46915 hub you referenced. I am going to need you to see if there are any part numbers stamped into the sides of the bearings. This would be the easiest way to identify a replacement. If you could leave that information along with your lug nut pattern in the comments below I would be happy to find you a replacement option. If you do not have any part numbers stamped into your bearings you'll have to measure your spindle with...

  • Do You Have a Replacement Spindle Hub Assembly?
    Hey Bob, thanks for the pictures. I do not know what part that is and I do not have a way of replacing it either. The only solution I have for you would be to replace your axle with one like the item # CE33201GA. What brand of trailer is that?

  • How to Identify Spindle on 1987 Trailer Switching to Trailer Wheels
    Hi Ed; unless you have some kind of hub that won't allow trailer wheels all you need to do is identify the bolt pattern. I attached a help article below which explains how to measure and find your bolt pattern. If you're swapping out the hub you can use the bearings to identify the spindle and which hub fits. The bearings will either have part numbers stamped in them or you can measure the inner diameter with a digital caliper # PTW80157.

    That depends on what's currently on your trailer Joe! There's no database available that I can look information up about what specific parts are on your 1994 Trailrite Trailer.

  • Can't Find Replacement for Older Dexter 22834 Hub
    Hey Randy, thanks for reaching out! We used to carry the 22834 hub back in the day as part 22834UC1, but it has long since been discontinued. I hate to be the final nail in the coffin for your search, but you're unfortunately chasing a ghost. In order to get your trailer up and running you're going to need to either have your spindles cut off and new (more common) ones welded on, or you're going to have to swap out your axle(s) entirely. If you can verify the weight rating of any axles...

  • Recommended Replacement Square 1.5" Spindle for a Boat Trailer
    Dave, the only two square spindles we have are the Square #84 Spindle for 3,500-lb Trailer Axles # TRU47FR and the Square BT8 Spindle for 2,000-lb Trailer Axles # TRU97FR. To figure out which one you have, you're going to need to pop your hubs off and find the part numbers for the bearings which should be stamped on them. If you're running a L68149 inner, L44649 outer, and a 58846 grease seal then you're using #84 spindles. If you're using a L44643 inner, L44643 outer, and 34823 for the...

  • How to Determine the Correct Replacement Hub for an Old Jetski Trailer
    The best way to determine the correct replacement hub is to go by the bearing numbers stamped into the inner and outer bearings. With those numbers and the wheel bolt pattern I can determine exactly what you will need. (I have linked a how-to article that explains how to measure bolt pattern.) If you want to measure the spindle then use the dial calipers because the measurements have to be as accurate as possible. Please refer to the picture I have included that shows where to measure...

  • Is There a Removable Spacer Which Fits onto Spindle Shaft Over The Grease Seal?
    While the grease seal area on the Spindle # TRU47FR is not removable it sounds like you are looking for something like the Seal Set # BB60002. This has a stainless steel ring which fits over the spindle to give it a smooth surface for the included grease seal to ride along. We also have this available in different sizes which are determined by the inner bearing size.

  • Solution for Replacement Hub for 1969 Orbit Trailer With LM48548 Inner and L44648 Outer Bearings
    Hello Ron; I'm sorry to say that we do not have a hub that matches that bearing combination. It is not uncommon for an older trailer like yours to have an obsolete bearing combination with no available replacement hub. Unfortunately, that means the only option is to replace the axle and switch to hubs that use a modern bearing combination. You will need to know the axle capacity as well as the hub face measurement to find a replacement.
