• Recommended Hanger Kit for a Triple-Axle Trailer Hanger Kit for Double-Eye Springs
  The recommended hanger kit for a Triple-Axle Trailer Hanger Kit for Double-Eye Springs is part # APTT1. This kit is designed to work on axles with capacities of 2,000 to 7,000 pounds. If your mobile home trailer axle is within this weight capacity this kit should work for you. I attached a picture that has a chart that shows exactly how you should space the axles when used with a 6-leaf spring for 7,000 pound trailer axles like part # e64SR.

• What is The Difference Between Having Trailer Axles Above or Below the Leaf Springs
  You can mount trailer axles above or below the leaf springs. The difference is just the amount of ground clearance that the trailer would end up having. The biggest advantage with the spring below the axle (trailer will be lower) is that you would have a lower center of gravity. The spring seats will need to be on the right side of the axle though when you go to install the new springs. Trailer axles have an arc to them so you can't just flip them over otherwise you would end up with...

• Where Do I Place the Spring Hangers on a Homemade Trailer w/ Three Axles?
  Hey Hyrum. I have no way of knowing where exactly to put the hangers on your homemade trailer. It depends on the length of the springs, equalizers, and what type of trailer it is. With a setup like you're dealing with I recommend putting the hangers back where they used to be. Hopefully the person who made the trailer did all the correct measurements originally. If not you'll need to disassemble the entire suspension system and start from scratch using something like the Triple-Axle Trailer...

• 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,...

• Triple-Axle Trailer Hanger Kit Recommendation for 7K Axles
  The Triple-Axle Trailer Hanger Kit # APTT3 that you referenced is designed to work on axles with capacities of 2,000 lbs to 7,000 lbs so it should work very well for you. I attached a picture that has a chart that shows exactly how you should space the axles when used with a 6-leaf spring like a # e64SR. From the outer hangers to the inner hanger you will need 24-3/4 inches, in between the two center hangers you will need 29 inches.

• Leaf Springs and Shackle Straps for Triple Axle Trailer with 7-3/4 Inch Equalizers
  The issue you are experiencing is a result of leaf springs that are too long for your hanger spacing. You will want shorter springs and I recommend also going with a capacity more geared toward your axles. You will want to use the Triple-Axle Trailer Hanger Kit for Double-Eye Springs # APTT5 and # APTT3 for reference. These kits are rated for 2,000 to 7,000 lb axles with almost identical spacing. My recommendation for you is the 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles...

• What is the Capacity of an Axle That Has Dexter 8-147 Hubs
  With you having a Dexter 8-147 hub, you will have a 3,500 pound capacity axle. The measurement you got with the lug bolts means you most likely also have their Vintage 4 on 9.4 bolt pattern, but with even wheels you need to measure center to center of bolts directly across from each other. However, the 8-147 hub is no longer being produced. They can still be found, but it is not going to be an easy process. What may be easier will be to replace the hubs with something much more common,...

• Differences Between Triple Axle Hanger Kits APTT1, APTT3, and APTT5
  The differences are the dimensions of the hangers and equalizers of the three kits. The # APTT1 uses totally straight equalizers and taller center hangers. The # APTT3 uses more traditional sized equalizers and center and outside hangers that differ in size slightly. The part # APTT5 uses a standard sized equalizer and hangers that are all the same height. The part # APTT3 is the one that is the most commonly used. It would be my recommendation for your trailer.

• Where to Place Tandem Axle Slipper Springs on Trailer being Built
  The slipper side of slipper leaf springs need to face the rear of the trailer. To determine the location for the front and rear hangers on your tandem axle trailer you will first need to make sure that you have the correct center point for your equalizer hanger. The center point of your equalizer hanger needs to be located where you will have 60 percent of the frame of the trailer in front of the center of the equalizer hanger and 40 percent behind the center of the equalizer hanger....

• Recommended Leaf Springs and Equalizers for Triple Axle Trailer With Double Eye Springs
  I saw you were looking at double eye leaf springs so we will assume that is what you have. In regards to leaf spring hanger spacing, the most common for a triple axle trailer is 29-1/2" first to second (center to center), 34" second to third (center to center), and 29-1/2" third to last (center to center). Therefore, it would be best if you would place the leaf spring hangers accordingly. Once the leaf spring hangers are in the above positions then you have a few options based on axle...

• Does Trailer Suspension 7-3/4 Inch Equalizer EQ-E1 Have a Weight Capacity
  Equalizer # TREQE1 does not have a weight capacity itself. It isn't bearing much of the weight compared to other components in a trailer suspension set up. If you have a tandem axle trailer then you could potentially use kit # APT5, # APT3, # APT9, # APT8, # APT7, or # APT3HD. All of these kits have the 7-3/4 inch long equalizers. For a triple axle trailer you could use # APTT5 or # APTT3. All of the above kits also come with hangers. If you do not need hangers then you would need to...

• Triple Axle Hanger Spacing for Trailer with 25-1/2 inch Long Springs Loaded
  The distance between the two center hangers will be more than the other distances since there are two equalizers on that leaf spring whereas the front and rear leaf springs only have one equalizer. You also have to consider the width of the equalizers when determining the spacing. A simple solution would be to replace your hangers and equalizers with the kit part # APTT3 and then use 29-1/2 inches between the hangers for the front axle and then 34 inches between the center axle hangers.

• Why do Trailer Suspension Hanger Kits Include Hangers of Different Heights
  The hangers of the part # APTT3 that you referenced are different heights because the center hangers attach to equalizers which then attach to shackles and then finally to the leaf springs. Since there are several components in this arrangement a slightly shorter or longer hanger is used for the center hanger so that when everything is put together the spring ends up sitting level. Basically the equalizer moves the attachment down and then the shackle straps move it back up and then depending...

• Troubleshooting Triple Axle Trailer with Rear Axle Off The Ground
  It is definitely not recommended to add different size wheels to one of your axles on your triple axle trailer. There is likely a miscalculation in axle spacing that is causing that third axle to sit off the ground. That definitely is not ideal and needs to solved. It is likely an equalizer, shackle strap, or hanger mismeasurement. Triple axle trailers do have different measurements than tandem axle trailers so you don't simply space the hangers out evenly. Based on your tire size,...

• Advantages to a Spread Axle Trailer over a Tandem Axle
  Spread axle trailers are pretty hard on tires when you are turning since the front tires will scrub and wear out quickly, also they are much harder to back up and are harder on suspension components. Spreads do have a little more flexibility with loading and in some areas can carry more weight, but that is something you would need to check your local DOT laws to confirm.

• How to Determine the Spacing Between Axles when Building a 4-Axle Trailer
  There are several things to consider when positioning axles on a trailer. I have included a picture that will help some but other factors include the springs and other suspension components you will be using. Also, a 4-axle trailer can potentially be a little troublesome because when turning the wheels can scrub (scrape the ground sideways). The closer the axles are together within reason the less likely this is to happen. But on 4 axles I do not think you will be able to avoid it completely. If...

• Suspension on Instigator 3-Axle Boat Trailer Hits Frame
  I did some research on your trailer and also read a few bad reviews from customers with the company. Since I do not have the trailer in-front of me, there is no way for me to say for certain that the suspension is mounted incorrectly. But, it definitely should not be hitting the frame under normal use. I would recommend having a trailer professional checkout your trailer to see if everything is mounted correctly. If you bought the trailer new, you may be able to contact the company and...
