bikemechanic53 Posted June 20, 2015 Report Share Posted June 20, 2015 I had a 3rd axle added to my 5th wheel a few months ago in Yuma. But the guys who did the work knew less about this than I did (despite what they said). So my 3 axles are not tracking correctly and the equalizers are hitting the stops on all the springs. This I assumed was from differences in weight each axle is carrying. But with the wheels jacked up off the ground, the equalizers are about in the same positions. See pict1. When I remove all the wheels, the setup looks like this, pict 2. The shackle straps flipped when I jacked the rv up. I assume I can get them back up the correct way. I hope the pictures are viewable. They have to be very small. Anyone have any ideas on what's wrong? Link to comment Share on other sites More sharing options...
TXiceman Posted June 20, 2015 Report Share Posted June 20, 2015 Might want to consider going to Mor/Ryde and get it redone there. I know it is a bit late for the suggestion. Ken Link to comment Share on other sites More sharing options...
bobsallyh Posted June 20, 2015 Report Share Posted June 20, 2015 bikemechanic53, may I ask who did the work in Yuma? Link to comment Share on other sites More sharing options...
Cyberdave Posted June 21, 2015 Report Share Posted June 21, 2015 From what I can see there are a couple things I would ask. Are the new leafs exactly the same as the OE? Same thickness, arc, number of leafs, same eye style and unloaded eye distance? Is the distance between the perches exactly the same on all three axles? Are the shackles the same length eye to eye? Can you get an image that shows the front and rear perches? I'm thinking the distance between perches are not the same or if they are the unloaded arc is different. I once helped a friend cheap out on a leaf spring change. His trucks leftside leaf spring so, we got a junkyard spring and then it was higher than the other... bad idea.

jpatrickc Posted June 21, 2015 Report Share Posted June 21, 2015 If I remember correctly on one end of the springs on a trailer with 2 axles has one end of the springs attached to a fixed location on the frame to keep the axles from moving forward or backward. On this setup the center axle is on 2 hangers that would allow one side to move forward and backward and mess with the alignment. Maybe it's not a problem but I would thing that it is.

Pat Pat, I think that would be the same also but the post from Dutch shows it hung this way. I need to think on the how and why... Link to comment Share on other sites More sharing options...
GeorgiaHybrid Posted June 21, 2015 Report Share Posted June 21, 2015 Cyberdave, one thing to remember, in the sketch above A and C are equal to each other but B will be longer due to the spring hanger design. This assumes the springs and hangers are the same. Link to comment Share on other sites More sharing options...
Star Dreamer Posted June 26, 2015 Report Share Posted June 26, 2015 On a two axle trailer A & B would be equal, if they did not move the one hanger between B & C, then that could be part of the problem. Link to comment Share on other sites More sharing options...
