• Can 1,500 lb Trailer Axle be Swapped for 3,500 lb Axle
  What you are looking to do is very possible. It would just be a matter of picking out the 3,500 lb capacity trailer axle that matches the dimensions your trailer needs. Also, the welder you spoke with is spot-on with recommending buying an axle with the flange already installed as they are actually harder than you'd think to weld on since it requires special jigs so that the alignment is right. So to pick out an axle the two important dimensions you need is the distance from hub face to...

• What Size Square Stock Should be Used with BT8 Spindle to Make an Axle
  The bar stock you use should be at least the size of the square part of spindle # TRU97FR which is 1-1/2 inches. Square axles are normally found in 1-1/2 inch and 2 inch sizes and there are suspension u-bolt kits for these sizes so I would not recommend using a different size because it might become difficult to source parts.

• Picking Out Axle for 1970 Dilly Boat Trailer
  You are going to need to measure your current axles in a few places to get the correct one as we don't have access to what your numbers reference. You will need to measure from hub face to hub face and then from the spring seat centers. You will also need to know what bolt pattern you have on your current hubs. I attached a help article on how to determine this as well. I also attached a link to a page with all of the axles we carry.

• How to Choose the Correct Spindle When Building a Trailer
  You will want to go by the capacity of the axle/trailer and get spindles that will match. So for example if the trailer/axle is rated up to 2,000 pounds using the TruRyde spindle # TRU97FR that you were looking at would work. You will also want to look at the bearings each requires (related parts on each spindle page, see link) and avoid an agricultural spindle because it can be difficult to get replacement parts for those. Then you will look at the hubs associated with the bearings the...

• Is It Possible to Just Replace Trailer Axle Spindle if Axle is Still Good
  If your axles are fine you can replace just the spindle and be totally fine. This is a common enough situation which is why we offer just replacement spindles like the part # TRU97FR that you were looking at. Trailer spindles must be installed by a qualified professional welder. Spindles must be welded on perfectly concentric or you will have tracking problems. A trailer shop will have the right jigs to allow the spindle to be welded on correctly.

• What Might Cause Tire Inner Sidewall Rubbing on Trailer Frame
  Sounds like your trailer axles are a bit too short if the inner sidewall is rubbing on the frame of the trailer. Did you recently change to a wider tire? That could be the cause too. Your equalizer being angled shouldn't cause the issue you described but it might be an indicator that parts are worn out or the hangers are at the wrong distance between each other.

• Is a Damaged Spindle Safe to Use If Hub Fits It
  It might seem that the spindle being slightly bent isn't a big deal but it can definitely lead to another blowout so you'll want to replace that spindle with a new one. It looks like you have a straight spindle like the standard BT8 found as part # TRU94FR for a circular end or part # TRU97FR for a square end. A damaged spindle will cause more friction which, in turn, increases the amount of heat produced which can lead to your bearings failing or a tire blowout. So any time a spindle...

• Recommended Replacement Spindle Or Axle For Older Spindle That Uses Short Hubs W/ L44643 Bearings
  I have a few different options for you, but the older short hubs that your trailers spindles use are not made any longer so I do not have a hub only option for you. Instead you will either need to replace the spindle with a newer one such as the # TRU97FR which works with idler hubs # AKIHUB-440-2-G-EZ-1K which have the 4 on 4" bolt pattern you are needing, or replace the entire axle. If you choose to go with a replacement axle you will need to measure your current axle from hub face...

• Replacement Trailer Spindle that Takes L44643 Bearings
  If both the inner and outer bearings are L44643 then you have a BT8 spindle. You can use # R104BT8, # TRU97FR, or # TRU59FR. All three of these spindles are rated for 1,000 pounds by themselves so they would be on a 2,000 pound axle. I have linked videos for all 3 spindles for you. Please note that installation of a spindle is a precision job that requires someone with experience in welding on spindles. If the spindle is welded on a little off then it can cause tire wear, suspension, and...

• How to Determine what Replacement Hub and Bearing Kit
  Thanks for sending a couple pictures! An agricultural spindle is mainly used in agricultural settings and best at low speeds. The best way to determine the correct parts for your homemade trailer, is to remove the hub from the trailer and either get part numbers from the inner and outer bearings and races, and grease seal or measure the spindle in 3 places and the hub in two places. I have included a photo showing the places to look for part numbers and places to measure. If the part...

• Recommended Replacement Axle For Homemade Trailer
  My recommendation is to replace the entire axle. That way you would not have any issues with replacement hubs, bearings, races, and other components you need for your trailer. I have attached a link to our product page for the axles we offer with idler hubs. You would need to measure your trailer to find the correct size axle. If you find you can use a 60 inch axle measured hub face to hub face I recommend part # 20440I-EZ-60. This includes the idler hubs with bearings, races, and seals....

• New Spindles, Hubs, Tires, and Wheels for a Canoga Concrete Mixer/Trailer
  The LM67048 is a pretty large bearing for a trailer that only weighs 400 pounds. So there isn't a hub that uses that bearing as both the inner and the outer. But if you are willing to remove the old spindles and have new ones welded on then I do have a solution for you. First for the spindles: I recommend a BT8 spindle # TRU97FR for a square stub or # TRU94FR for a round stub. These spindles are usually found on 2,000 pound axles so they have plenty of capacity for your cement mixer trailer. The...

• Trailer Hub w/6 Lug Pattern, Inner Bearing Inner Diameter 1.5, Outer Bearing Inner Diameter 1.25
  Bearing measurements need to be as accurate as possible, to at least the thousandth of an inch, and require calipers if you have to measure them. Otherwise look at the bearing numbers that are stamped into the sides of the bearings. With those numbers we can determine a lot about the running gear and if anything else will fit. If the measurements are exactly 1-1/2 and 1-1/4 inches then the only option we have would be agricultural hub # AH30660FCOMP which has a 6 on 6 bolt pattern. If...

• Why Are There Both Round and Square Trailer Axles Used on RVs
  Most of the OEM axles installed in RVs and most of the replacement axles we offer are indeed round in cross section. We do offer some square stub spindles for use on square axles, such as # TRU97FR, but these are usually limited to lower capacities like utility trailer applications. We do not have the ability to ship high-capacity axles due to their weight.

• Single or Tandem Axles for Homemade 24 ft x 98 Camper?
  Most campers that long are tandem axles so I would go that route. I took a look at some common GVWR's for campers of that size and it was in the 5,000 lb - 7,000 lb range so you need to keep that in mind; something like the 89" Dexter Trailer Axle Beam with E-Z Lube Spindles # 8327830 might work. You can also take a look at the help article I've added about where to position your trailer axle which should be useful.
