• 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...

• 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...

• 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...

• 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...

  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...

• 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 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...

• 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...

• 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...

  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. I am going to need you to take a look at the actuator and see if you can find a part number and email me back or comment below. I would also need to know if you have disc or drum brakes.

• Replacement Disc Brake Kit Recommendation for 3,500 lb Axle with #84 Spindles
  Thank you for all of the photos and information! From what I can see it looks like you have a #84 spindle but that inner bearing blew out so you should be able to remove that inner sleeve that looks like it's still on the spindle (next to where the grease seal rides). Try using a hammer and flat head screwdriver to gently tap on that ring to see if it slides off the spindle without damaging anything. If you can get it off and your spindles look clean and don't have any damaged then it's...

• How to Determine Capacity of Square Axle
  Square axle capacities are pretty hard to determine. Unlike round axles, they do not have set capacities based on their dimensions. Based on the bearings your hub looks like it's rated for 3,500 lbs. Most likely that would be the same rating as your axles.

• Determining the Capacity of a Square Trailer Axle
  Square axles can be tough to determine capacity. Often times the same spindle fits a range of axle capacities. The best way to determine the capacity is to get the inner and outer bearing numbers stamped into the metal of the bearings. Going by those numbers, wheel size, and bolt pattern, we can determine the probable axle capacity. I have included some links that might help. There could also be a plate on the axle itself that lists the capacity. The most common place to find axle capacity...

• Spindle Recommendation for a Square 2x2 Axle
  For your 2 inch by 2 inch axles you would want a Redline Spindle for Square Axles # TRU47FR. This is a square spindle designed for 2 inch square axles so it should work for well for you. Check out the review video I attached. The EZ Lube Spindle # TRU74FR you referenced is designed for round axles so it would not work for you. Spindles should be welded on by a qualified welder.

• Replacement Hubs That Use the Inner Bearing LM67048 and the Outer Bearing LM11949
  From the measurements provided in the photos, it looks like you have an inner bearing that has a 1.250 inch inner diameter and an outer bearing # LM11949, which has a .750 inch inner diameter. This leads me to believe you have some variation of agricultural hub, like the Redline Trailer Hub Assembly # AH15450ECOMP. This will use the inner bearing # LM67048 that will have the inner diameter of 1.250 inches. That being said, this has a 4 on 5 bolt pattern and will not match your 5 bolt wheels. What...

• Tips for Determining Square Trailer Axle Capacity
  Square axles can be tough to determine capacity. Often times the same spindle fits a range of axle capacities. The best way to determine the capacity is to get the inner and outer bearing numbers stamped into the metal of the bearings like you did. The numbers you listed do not match any of the spindles we carry though so I was not able to determine anything from that. The bolt pattern of the hubs on the trailer is typically used on 2k-3.5k axles, most 15 inch wheel trailer setups have...
