How to Install Axle-Less Suspension on an Off-Road Trailer

Video Tutorial: Steps on Installing Your New Timbren Axle-Less Suspension

We met up with Arcworxs in Bozeman, Montana to catch an inside look at how they installed the Axle-Less trailer suspension to their new off-road trailer. Check out this DIY tutorial and see for yourself detailed instructions to install an Axle-Less trailer suspension on your own.

Here are the basic steps as demonstrated in the video:

1. Make sure the trailer frame is perfectly square.


2. Bolt outboard arms onto corresponding control arms using fasteners supplied.


3. Install hangers to frame using proper steps: 
   
   
   
   • Mark frame rails where the centreline of spindles should cross frame.
   
   
   • Clamp hangers to frame making sure centre of spindles line up with marks on each frame rail. Confirm measurements are equal.
   
   
   • Bolt hanger side plate to frame using holes in the hanger side plate as a template.
   
   
   • Drill horizontal holes through the side of the frame. Use 5/8” UNC (grade 5 minimum) bolts, lock nuts, and washers to mount hangers to frame. 
   
   
   
   


4. Adjust for proper camber and toe.


5. There are two options for frame reinforcement:
   
   
   
   • Bolt a reinforcing bracket to the inside of the frame (as suggested in video).
   
   
   • Weld or bolt a cross member to the hanger.
   
   
   
   


6. Install brake or idler hub to spindle. (Follow details in video)
