Center Hanger Interference Troubleshooting for a Tandem Axle Trailer Converted to Single Axle

Question:

I recently bought a 1993 Eagle 3500lb single-axle utility trailer. On getting it home I noticed a problem with the suspension, which is that effectively the bed is sitting directly on the axle. The frame is not in exactly in contact with the axle, but on both sides what appears to be the middle spring hangers for a tandem setup are sitting directly on the u-bolts springs mounted under-axle. Could this trailer have been a tandem that was converted to a single? Should I grind off the middle hangers, or is this a valid setup? Are my springs just shot? Sorry I dont have a pic.

If I am understanding you correctly it sounds like there is a center hanger mounted directly above the axle of your trailer (that is on top of your leaf springs) that is preventing the trailer suspension from being able to travel. If this is the case I would remove that hanger as it is preventing your trailer suspension from functioning.

If the springs are flat without any bow to them they might be overloaded or just worn out. If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible.

You will want to also measure the distance from eye to eye of your old leaf springs and then pick a leaf spring with the same weight capacity of your trailer axles and is slightly shorter (around 1 inch) to compensate for the sag and wear of the old leaf spring.

Leaf springs should be replaced in pairs to help keep your trailer stable while being towed.

I have attached an FAQ articles that reviews trailer suspension components for you below to check out.
