• Do Trailer Spindles Just Weld to End of Axle
  So the install of a spindle like the # TRU97FR really needs to be done by a welder who has done the job before and has the special jigs for the job. It's a precision job and we can't recommend a method for it aside from taking it to someone who is equipped for it. Otherwise your alignment will be off.

• 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...

• How to Determine The Correct Replacement Trailer Hubs by Bearing Numbers or Spindle Size
  The best way to determine which replacement hubs you need for your trailer would be to remove one of the hubs and retrieve the bearings.

I have included a link to our spindle main page. At the top of the page is a diagram showing all of the measurements we would need to find the correct hubs...

• Do Trailer Bearings Fit Tight To the Spindle they Install On
  Bearings fit pretty tight onto spindles. There basically should be no play at all between the inner portion of the bearing and the spindle. They don't fit so tight that they would have to be pressed on, but they sometimes can be tight enough that they require a bit of effort to get them totally slid on. Check out the install video I attached for more info on how bearings install.

• 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.

• 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...

• Could a Hub Get Replaced on the Side of the Highway
  Spindles get welded to axles so there really is not an easy way to replace one on the side of a highway. The best advice I could give to you would be to periodically check the condition of the bearings on your trailer and be sure to grease them regularly and you should have a pretty reliable trailer setup. If you had a replacement hub in your vehicle you could pretty easily swap one if needed. Check out the video I attached on bearing inspection for you.

• Troubleshooting Tire Wear On Outside of Front Trailer Tire
  Typically, when the outside edges of a tire are showing wear its because the tires are under-inflated. The solution is to inflate the tires to the maximum pressure listed on the sidewall in this situation. Check the suspension for worn out components or holes that are egg-shaped instead of round where the suspension components come together. Rusty components won't necessarily hurt the way the tires wear, but you should still check them.

• Can a Trailer Spindle with Grooves Still be Used if Bearing Fits
  You will have to replace the spindle. Grooves that can't be taken out with emory cloth will eventually cause new bearings to fail which will leave you stranded with a locked up wheel most likely. 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...

• Process for Changing a Damaged Spindle on a Trailer Axle
  Replacement of a spindle on a trailer axle is best left to a professional installer. This is not a do-it-yourself type of project. We urge you to use a professional welder experienced in axle fabrication. Proper alignment and welding are critical to safe operation of the trailer. Depending on the condition of the axle you may be better served by replacing the entire axle/spindle assembly. Although the axle adds to the parts cost, you will save on the labor side. A new axle with spindles...

• Most Accurate Way to Measure the Length of Axle
  When it comes to the bearing that rides on the spindle, there really is nothing to keep it from rotating other than the compression from tightening the spindle nut. The most accurate way to determine the length of your axle is to measure the distance from hub face to hub face (A) and spring center to spring center (B). I have attached a picture to illustrate this measurement. With only one hub on the trailer, to obtain measurement A you would need to double measurement C and add it to...

• Trailer Spindle Got a Nick In it from a Grinder Should the Axle be Replaced
  How deep is it? It is hard to tell from the picture. You may be able to use some emery cloth and take care of it unless it is too deep. Then you would want to go ahead and replace the axle. Even though spindles are available by themselves you would need special equipment and experience to weld on a new one so that it is straight. Replacing the axle is the safe bet. I have included a link to the axles we carry to the right.

• Solution for Replacing 1-1/4" Square Axle on Boat Trailer
  Your best option will definitely be to replace the entire axle. There's a decent chance that some damage was done to the axle during your recent mishap beyond the slight bend that could compromise it's integrity going forward.
