Torsion axle alignment out

975 Views 22 Replies 12 Participants Last post by  skidoo6002018
After a 120 mile highway ride (60 up and 60 back) this past Sunday and having the right side tire blow out on the highway, I see my left tire severely worn on the inside. I measured outside to outside front/rear and the left wheel is 1/4" toed out. This would explain the sudden wear. Both tires were fine the day before.
Anyone ever try to force one into alignment? The trailer is a 12' x 102" enclosed SnoPro. I was hauling the SxS at the time.

To my knowledge there is no adjustment. Without seeing the condition of your trailer, I'm going to assume the axle is junk.

I have bent a trailer axle back to near alignment once in the past. It takes some heavy chains and the like to accomplish. It was not a torsion type.

Examine the axle to see if you can see a bend in the tube somewhere. That would be reasonable to do. If where the spindle is welded in to the arm or the arm is bent, then that would be much harder to bend back. As suggested, replacing would probably be the best at that point.

BTW, don't just apply heat and bend with an oxy torch. I will soften the steel and may well just bend again at that point.
My plan is to pull sideways on it to see what happens. I'm suspecting that the rubber inside has deteriorated and allowed the inner tube to move. The outer tube itself is straight. I've had this trailer since last year, never had an issue before, and it has never seen any trauma.

Time to call or stop by the trailer outlet (Tilton NH)for a galvanized axle and tire upgrade .Proline also does this service by appointment in Milton NH

That appears to be overloaded to me... Bent is also likely.

Maybe overloaded. How heavy is the sxs?

GVWR: 2990
EMPTY WEIGHT: 998
LOAD CAPACITY: 1992
Dry weight is 1653lbs. With fuel, spare, storage case I might be at 1800. Overloaded for the axle or tires?

Took some dimensions to price an axle.
Everything seems good and tight.

Seem to be getting close to the limit. Any accessories added to the trailer or sxs will put you even closer. Can you still see the bend with the trailer loaded or does it flatten out?

Definitely overloaded then... You're at max capacity with the wet weight of the SxS it seems.
I believe I am close to capacity but still under the rated limit. 3500 lb axle, the trailer weighs 990 according to the placard. This leaves 2500 for the cargo and there's no way I'm at that. And if I was 1 lb over I wouldn't think that would be the failure point. All the weights are static since the the owner cannot account for dynamic situations like rough roads, potholes, etc... Looks like I'll be swapping out the axle anyway. When I measured the mis-alignment it was empty.
From what I've seen the hybrid usually has a 3k axle.
I think that slight bend in the axle is normal.

The bend is normal, but I would guess that it would flatten out when overloaded, causing the tires to ride on the inside.

It's a v-nose, not a hybrid.

As stated in my original post, the left wheel is toed out 1/4" front to back. The tire was severely worn on the inside edge. Right side is fine.
Below is the placard. I appreciate the help, comments, and ideas.

Depending on the axle manufacturer it's likely over loaded. Something I've discovered in recent history is that all axles are NOT created equally. I'm a marine mechanic and run into King trailers with your exact problem regularly. The same EZ Loader brand trailer (same weight rating that is) will work well with even tire wear for many years where as the King will eat tires starting the first year. Swap in a known, good quality and slightly heavier rated axle and you'll be much happier......especially if you can jump up to a standard trailer tire size from the little donuts.

Can't quite see the numbers but it looks like the GVWR (Gross Vehicle Weight Rating) is 2980 lbs......? So you have right at 2000 lbs capacity for total cargo weight. The SxS plus some ramps and tools and such would put it over GVWR.

Looks things are right on the edge, and the designer's would expect it to survive just so much transient overload from the bumps and such, and if you are right at the GVWR, then it won't take much transient impact to start bending/breaking stuff.

Check to see if the mounting bracket (to the frame) has been tweaked on that side, and that the frame is perfectly straight through that mounting area and does not have a slight S-bend in it.
The bend is normal, but I would guess that it would flatten out when overloaded, causing the tires to ride on the inside.
You would be amazed to see how much these tube axles bend on a double axle trailer in a tight turn!
It says on the tag that the cargo should not exceed 1690#'s...
You're right but I think that's the sticker for rating the original tire. I would hope that is per wheel otherwise two lightweight snowmobiles puts you at or over limit.
Anyone?
