When positioning a trailer axle or adding an additional axle, the key is to make sure that the axles are located in just the right position so that roughly 10 to 15 percent of the total trailer weight is placed on the tongue. Finding the correct axle location can take some trial and error, so it is best to mock up the locations for all the suspension components until you know everything is in the right spot.

Brakes can be installed on only one axle of a tandem axle trailer, however you should first check your state laws to see how many brakes are required for the gross vehicle weight rating (GVWR) of your tandem axle trailer. Some states require a specific number of brakes based on the maximum weight capacity of a trailer.
If you are able to install brakes on only one axle, I recommend installing them on the front axle if you use a torsion axle or on the rear axle if you are using tubular... view full answer...
This is a really great question but it depends on what the trailer will carry. For most applications you'd want the front axle of the tandem axle trailer to be the brake axle but if it's a boat trailer (particularly with an outboard motor) you'd want it to be the rear axle. Basically it comes down to which axle would be carry more of the trailer's weight. view full answer...
The recommended placement of an axle on a single axle trailer will be determined by tongue weight. There are two formulas to determine axle placement. One formula is for trailers with a tongue weight (TW) greater than 10% of the gross trailer weight (GTW) and the other formula is for trailers with a TW less than 10% of the GTW. You can find each of these formulas pictured below.
Before you can use either of these formulas you will need to have the axle already placed under the trailer.... view full answer...
Most people will put the brakes on the front axle of a tandem axle trailer or the front two axles of a triple axle trailer. This is what I recommend doing if you are not wanting to install brakes on all of the axles.
For the most effective braking system though, I recommend using brakes on all 3 of your axles. This will help your brakes last longer because they won't be working as hard individually and it will help give you better braking performance.

You would put the brakes on the forward axle of a tandem axle trailer and not the rear axle if you had to choose one axle. If you are referring to the video, that particular trailer did not have brake mounting flanges on the forward axle or it could be the one we worked on that only needed new parts on the rear axle.
Either way traditionally you would put the brakes on the forward axle. view full answer...
The rule of thumb is that you want to put the brakes on the axle that is going to see more weight. For boat trailers where the motors (most of the weight) are at the rear of the trailer you will see the rear axle with the brakes.
For utility trailers where most of the weight is in front of the axles the front axle is used.
I attached a couple help artilces on adding brakes to trailer axles for you to check out as well. view full answer...
You can certainly install brake assemblies and drums on the rear axle of your tandem axle trailer, and they'll bolt right up as long as the axle has a brake mounting flange installed on it.
If the rear axle uses the same bearings, and the hubs have the same wheel bolt pattern, you can use the same # AKEBRK-35R-SA and # AKEBRK-35L-SA brake assemblies and # AKHD-550-35-K hubs you used last time. view full answer...
As long as you have at least 2-1/2" between your axles and the frame of your trailer when it is unloaded you should be good to go.
Altogether your leaf springs should only be deflecting about 1-1/2" when carrying a load.
If you wanted to increase your clearance then there are a few ways to do that. One way would be to cut your current hangers off and have longer ones welded on and another way is to use an over under kit like part # K71-384-00 for a 2-3/8" axle or part # K71-385-00 for... view full answer...
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.

You can add the Timbren Axle-Less Suspension System, # ASR1200S01, to your trailer in combination with your current axle, but there are a few factors that you will want to consider first. To add this system to your trailer, you will need to move your current axle either forward or backward to ensure that the weight of the trailer and any load is distributed to both axles properly.

I may have an option for you, but we do not have a breakdown of which axle your 2019 Forest River Rockwood Geo Pro 15TB Travel trailer uses so you will need to measure the axle, and determine its rating.
Starting with measuring the axle you will need to measure from hub face to hub face, and from spring center to spring center. This will tell us the length of the axle needed, and how wide the frame of your trailer is.
For the axle rating the easiest way to get this is looking for the... view full answer...
It is possible to add the Timbren Axle-Less Trailer Suspension System # A35RS545 to your horse trailer in combination with one of your current torsion axles, but there are two important factors to consider before you do so.
You will want to take into account the distance from the center of the spindle to the trailer frame and the amount of deflection. For example, the # A35RS545 will put the center of the spindle 4" below the bottom of the frame when empty and it has a deflection of 1-3/4".... view full answer...
To answer your first question, we have not changed the axle locations to the bottom of the axle set with the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers # RM-2450.
As for the potential ground clearance issues, it is important to note there are specific directions for installing this kit with the axle above the leaf springs. It is designed to be installed with the trailer loaded but with the axles above the leaf springs you must support the trailer frame with jack stands.... view full answer...
If you were happy with the ground clearance that the trailer had with the old setup then I would recommend you stick with the way you had it with the axle below the springs. If you moved the axle above the spring you would lose ground clearance and would have to re-weld the spring seats on the axles.
The only reason to switch from what you had would be if you needed the trailer to sit lower. We do sell kits to move the axle though.

The bend in the axle needs to be installed pointing upward, not down. If the axle is installed with the bend going toward the ground instead of toward the underside of the trailer, it will cause the camber of the wheels to be wrong.
Since your springs touch the top of the axle instead of the bottom, you will want to have new spring seats welded to the top of the axle.
For an axle with a 1-3/4 inch diameter like # 20545I-EZ-72-10 that you referenced, you will want a spring seat designed... view full answer...
To convert your single axle trailer to a double axle, you will want to start with some basic measuring. Then you will want to determine if you will be we matching your current axle or replacing it. If you are matching your current axle, you will need to get the spring seat to spring seat dimensions and the hub face to hub face dimensions and I can assist from there.

Yes, you can add a second axle with a Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Off-Road Tires - 2,200 lbs # ASR1THDS02. When adding a second axle, you will want to ensure that they are the same capacity and use the same size wheels, etc. When adding a second axle the pivot point of the trailer changes, so where your current axle sits is where you would split the distance for a tandem axle application or where your center hanger would need to be if you were... view full answer...
Standard axles, like the Trailer Axle with Idler Hubs # e65GR, have a slight bend upward so that when you have the trailer loaded the axle is straight. If the axle becoming straight is the slight bend you're talking about then this is completely normal. If the axle is actually bending downward then it was either installed upside down or it has been compromised and is not okay to use.
If you can let me know the hub-face and spring center measurements for your axle I can see if we have a... view full answer...
Since you are building a trailer I first want to state that using quad axles isn't ideal. It will cause tire scrub as there becomes too broad an axle base for the trailer to track as nicely. That is why most trailers will use tandem or triple axles as needed for load capacity. If you just want to add the 4th axle for overbuild reasons it will bite you as you will need to replace tires more often. Most of the professional semi flat bed trailers that have the quad axles are for transporting... view full answer...
