• How to Pick Out Replacement Hub for Trailer
  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. You will need to go with a hub that matches the weight capacity needed and the bolt pattern...

• Is It Ok To Use A Scratched Spindle On A Trailer Axle
  It will depend on how deep and long the scratch is. You want to make sure the bearing will still get a good purchase on the spindle, but you will also need to make sure the seal will not have a gap that will allow grease or oil to leak out. If the bearing is sitting weird or if there is a gap with the seal, you will need to replace the spindle. We do have a bunch of different options for this and I included a link to our spindle page, just in case.

• Troubleshooting Single Tire Overheating on Tandem Axle Trailer I have a 2 axle trailor with 4 bran
  I'm assuming since you mentioned the psi for the tires that you have them inflated correctly. Trailer tires should be at the max psi unless the manufacturer says otherwise. Since you don't have any uneven wear, and nothing else is overheating aside from that tire, it sounds like there is an internal issue with the tire itself. It might be a loose belt or something similar. Since these are new tires, I would contact the manufacturer and see about getting a replacement under warranty. If...

• Troubleshooting Excessive Tire Wear On The Inside Of Left Front Tire Only
  Generally, if a tire is wearing on the inside, it is due to an overloaded axle. However if it is only happening on one side, I suspect a bent axle or spindle. Especially if you have been going thru tires like that, there is definitely something off with the left front spindle. Diagnosing a bent spindle can be tricky, even a slight bend of a few hundredths of an inch can throw it off. You would want to take your trailer to a professional trailer axle shop and have them look at it. Spindles...

• Replacing a Damaged Trailer Axle
  Having the bearing numbers and spring seat measurements, you will definitely get most of the way to finding new parts, but you will need a couple more things to confirm the replacements will be correct. The spring seats are only half of the measurements needed to find the correct axle. You will need to measure from hub face to hub face to make sure the total length of the axle is correct as well. Granted with your hub and spindle being damaged, you will just need to get it as close as...

• Does Chipped and Burned Spindle Need to Be Replaced
  The chips and the burn mark on your trailer spindle is an indication that the inner bearing overheated. That is definitely enough damage that you need to seriously consider replacing the spindle otherwise that damage could then chip and damage any replacement inner bearings you install. I can't quite make out from that photo what size spindle you have but if you can let me know the axle capacity I'd be happy to help you select a replacement from our linked selection!

• How to Accurately Measure Spindle Dimensions
  The range of trailer spindles we offer is shown on the linked page. These include both round and square stub types rated for axles ranging from 2,000 lbs to 7,000 lbs. On the chart you can see the key dimensions for five points on the spindle, including where the grease seal rides (B) and where the bearings ride (C and D). Spindle dimensions must be taken with precision, to the nearest few thousandths of an inch; fractional dimensions are not accurate enough so you will want to use a precision...

  Yes, that spindle does look too beat up to be usable. I attached a link to this page that has all of the spindles we carry. You would need to pick out the one that matches the axle capacity on your trailer. It looks like maybe a 2,200 or 2,000 lb axle possibly like the # TRU59FR.

• Availability of Spindle that Would Fit Square Tube Axle
  New spindles should be welded on only by a professional welder who has experience and the correct jigs for installing spindles perfectly straight and concentric. If not installed correctly the trailer may not track properly and uneven tire wear can occur. It might be more trouble than it's worth to try and fit a round spindle like the part # TRU24FR in a square tube axle by trimming it. We have a square version of this spindle as part # TRU47FR.

• How To Determine If ST205/75R15 Tires Can Replace ST205/75R14 Tires On 1995 Travel Trailer
  It is possible that the ST205/75R15 will be able to replace the 205/75R14 tires currently on your 1995 travel trailer but you will need to take a few measurements to determine this.

• 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...

• Replacement 3500 lb Axle for 5x12 Single Axle Utility Trailer
  Rather than trying to assemble axles from tubing and spindles, I'd highly recommend you go with a manufactured axle. Having a manufactured axle will provide you with a known weight capacity. Welding spindles to an axle tube is a very specialized skill that shouldn't be farmed out to that dude down the street who knows how to stick things together. 2-3/8 inches is the typical OD of axle tube for a 3500 lb axle. We offer some stock off the shelf axles in a 3500 lb capacity. The axles have...

  You have a 2-3/8 inch O.D. pipe so you might want to look at #84 Spindle, # TRU84FR, which has a 2 inch O.D. at the weld point and has a 1750 lb. capacity, so two spindles will give that axle 3,500 lb capacity. The #42 Spindle, TRU57FR which has a 2.25 inch O.D. at the weld point and is rated for 5,200 lbs to 7,000 lbs axles.

• What Spindle Should be Used to Fit in Axle Tubing of 1-7/16 inch And 2,000 lb Capacity
  The best spindle option we have is the 2,000 lb axle spindle part # TRU94FR which has an outer diameter of where it would install in an axle of 1.25 inches. As far as the diameter of tubing to use for the axle we really can't recommend that and be able to ensure you'd have the capacity you'd need.

• 84 Spindle with Brake Mounting Flange Recommendation
  Adding brake mounting flanges to a spindle is something that only a qualified welder with experience welding them on should do. A much easier solution would be to go with a spindle that has a flange mounted to it already like the part # TRU74FR that would fit the same hubs as the # TRU47FR that you referenced. Also, the # TRU47FR is a square spindle and we only offer flanges for round spindles.

• Does a Spindle with Scarring and Complete Bearing Failure Need to be Replaced
  What concerns me about this situation is the scarring on the spindle. Depending on how deep and how bad the scarring is, a new set of bearings and a new hub/drum assembly might experience the same problem down the road. This would mean that the spindle would need to be replaced also. Otherwise, you may have to frequently replace parts. It would be best in this situation to eliminate the possibility of future similar occurrences before they have a chance to cause damage. Any visible scarring...

• Measuring Spindle for Replacement Oil Seal
  The seal will be a similar size but it all depends on the spindle itself as to the actual size. It should have a tight seal so you don't leak oil but most systems use grease which also needs a good seal. The best way to determine the correct fit for your specific axle is to use a digital caliper to measure the spindle at that location. I've attached a photo to assist. Once you have that measurement you will have the inner diameter for your seal and then you will measure the back of...
