Moving axle

Postby PJLangevin » Sun Jul 08, 2018 9:55 pm

If the axle is over the spring, can I move it under the spring?

usually yes

if it is a square axle it will usually be a simple unbolt, slide out and bolt back up usually using the same hardware

if it is a round axle and the spring pads are welded on you have different issues to deal with

either way you have to maintain the axle's orientation

¿ what style axle do you have ?

pics would help

I did it just fine. Make sure you have clearance above the spring to allow axle movement. I notched my frame to allow for this.

Overall it was a piece of cake, and gave Rose a 4" drop.

You will need to remount your fenders too.

Here a few, not great, sorry. The wheel wells have to be modified. This is trailer #2. I've attached a photo of trailer #1. We are renovating #2 to have queen bed in it. ImageImageImageImage

I just saw that I misread your original question. Doing the flip to below should be even easier than bottom to top.

You get ground clearance, but your galley gets higher, so do the door sills.

No, it's me who got it backwards. I need to lower it so the galley is lower. The teardrop unit is fine, its the little Lark that we need to lower.

So its overslung - leaf springs sit on axle - and you want it underslung. I did that to my NT 5x8. I still have 3" and I'm pretty sure that's enough. Can you measure how much travel you will have if you undersling it. Depth of axle minus clear to frame or other obstruction above spring?

Try this https://www.suspensionmaxx.com/tech-sup ... alculator/

I think I would get as much info about total weight and look at e-trailer for the right u-bolts and plates. Overslung the bolts just hold it in plate. Underslung the bolts have all the gravity load - which isn't a lot for steel bolts in tension. Probably overkill but I'd look for grade 8 and as big in diameter as possible.

But the travel is key - how far the leaf springs will deflect.

I jope this helps.

Thank you for the information, I will measure it and try to figure it out. Right now, the trailer sits about 24" off the ground, would like it a bit lower. Would replace the axle with Timbren, but the budget is well... I have this trailer on the go and the teardrop as well. So for now will just try and move the axle.
