Torsion Axle Failure

I have an almost new Windjammer that had both torsion axles fail causing the trailer to lower to the point the tires rubbed on the bottom of the wheel wells. Contacted Rockwood warranty service and they are supposed to ship two new axles to a local dealer for repair. I had torsion axles on my last trailer and never had any problems with them. Anyone here have their torsion axles fail?

X2 on the photos. Did both sides fail, or just one side of one axle, and then the second on that side failed possibly due to over loading the remaining axle?

Since I have been a member here, never seen a post about a torsion axle failure and that is what I have on my trailer. Photos would be great to inform everyone.

I think the axles were defective from the start as I always had very little tire clearance. Talking with the Rockwood representative and two dealers, there should be about 1.5 to 2 inches clearance to allow for movement when underway.

I have wheel well rubs on 3 of the 4 tire locations. Left side was the worst. Both left side tires were toast but right side were very nearly rubbing as well. This was with the original 225x75 tires. Of course this happened Saturday afternoon 300 miles from home and not near any town of any size. Had to get smaller diameter tires 205x75 to get home. Had about 1.5 inches of clearance with the smaller diameter tires.

Contacted Rockwood warranty service on Monday and they will be sending two new axles for a local dealer to install and repair the damaged wheel wells. He also talked about reimbursing me for the tires I had to purchase. Will see if Rockwood comes through on everything promised.

Looked at the trailer on Monday afternoon and the left front tire is nearly touching the wheel well again so I have lost my 1.5 inches of clearance that I had with the smaller tires.

I will take some photos this weekend and post.

Photos shown

1 - Left front tire with barely enough room to fit finger in flat. This tire had about 1.5 inch clearance after tire was installed. Dropped since.
2 - Left rear with about 1 inch clearance. This one dropped too but not as much.
3 - Right side with about 1.25 inch clearance on both tires.
4 - Right rear closeup showing two finger clearance.

Bear in mind that these are the replacement 205x75s tires and not the original 225x75s that came on the trailer. There is about 1.25 inch difference in diameter between the two sizes. The original tires will not fit anymore.

Can you get a picture(s) from under the trailer showing the attitude of the axle arms? Would be interesting to see if they are level or slightly uphill toward the spindle.

Lots of information here about these axles.

Hope some of it helps. You might have the wrong axles for your weight.
Check the axles for the name plate and look up the correct axle for your camper.

More Photos

Took a few more photos this morning. The mechanism looks to be parallel with the trailer frame. I don't know how it is supposed to be but I would think it should be parallel. Axle decal shows 4000 pound axles which is what the Forest River plate says on the side of the trailer. Too bad, as if it were undersized that would explain the issue.

When was the last time you weighed it?

The attached graphic shows that slightly below parallel the axle is at its rated load.
When level you are over loaded.
