• 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...

• Torque Spec for Square BT8 Spindle for 2,000-lb Trailer Axles
  If you're referring to the spindle nut on the Square BT8 Spindle for 2,000-lb Trailer Axles part # TRU97FR. there is no torque spec. There is no torque spec for any spindle nut. I usually will tighten the nut down snug and then a few turns with pliers to seat the grease seal. Then, back the nut off, tighten down till snug and back off 1/4 turn until the retainer or cotter pin slot lines up.

• Identifying Replacement Wheel Bearings for Unknown Hubs on Boat Trailer
  The easiest way to identify the needed replacement bearing kit is to obtain the reference numbers off the existing bearings. Your best bet would be to clean the existing bearings and closely examine them for the reference numbers. Given the inside diameter you provided, the bearings could be a # LM67048, # 15123 or # 14125A, all of which have a 1.25 inch inside diameter. All three bearings are listed as outer bearings for certain hubs, none of the hubs we offer would use these as both...

• 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.

• 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...

• How to Use an 18 Inch Diameter Wheel on a Trailer
  I understand the look of using the same tire on the trailer as the tow vehicle but there are not going to be any performance benefits. In fact, using a passenger tire on a trailer is actually going to give you less performance than using a special trailer tire. The issue is that passenger tires do not have the sidewall capacity that is needed for use on a trailer. Trailer tires are going to experience much more flex than a passenger tire so the sidewalls need to be much stronger. I can't...

• 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.

• 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. We don't have any square axles similar to what you described having on your boat trailer, but a really good option for replacement is a Timbren Axle-Less System like 3,500lb # ASR3500S05. With this setup you don't need to worry about finding the exact same length...

• Can Damaged Axle on 1999 Shorelander Boat Trailer Be Sanded Smooth
  In all honesty, you're almost certainly going to be best off by replacing the axle. The spindles are likely gouged in the locations where the bearings ride. The act of sanding out the damaged area of the spindle has likely removed some material to the point where the spindle is no longer within its diameter specifications. This means the bearing won't fit well on the spindle, and might spin against the spindle which can cause it to heat up to the point where it could be damaged. We offer...

• 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.

• 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...

• 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...

• How to Pick Out an Axle for a 6 x 12 Utility Trailer
  Basically you will want to measure your trailer to determine where you will want the wheels of it to be so that you can pick out the correct length axle. There is not a set length of axle that a 6 x 12 trailer should take so you will have to determine about where you want the wheels to be and then measure the distance between where the mounting flange of the rims would be. The only size 3,500 lb axle we carry is the part # 35545I-EZ-89 which will have a distance of 89 inches from hub face...

• 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...

• 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.

• How to Check for a Bent Trailer Axle Spindle
  Assuming your tires are in good shape without any bulges the easiest way to determine if you have a bent spindle is to take a straight edge that is longer than the tire and lay it across the tire parallel with your trailer frame and then measure the distance from the frame to the straight edge in front and back of the tire. If the distance is the same then the spindle isn't bent. Beyond that your best option would be to take the trailer to someone qualified in trailer repair to have them...

• 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. Find the numbers stamped into the bearings and with those we will be able to get you the correct hubs. If you are unable to retrieve the bearing numbers, you can take measurements of the spindle.
