I have a heavy duty aluminum I beam single torsion axle Wesco trailer, 4200GVW. Axle has a 6000lb tag on it.
Problem is that the axle mounts are twisting and the welds are starting to crack.
I am not the origional owner but there is not more then a couple of thousand miles and the thing still looks new.
I am in the process of contacting the manufacture and was wondering if any one has had a similar problem.
Thank`s if you can help.

Re: Wesco Trailer torsion axle problem

Just because you have a 6000 lb. axle doesn't mean you have 6000 lb. springs. And a 4200 lb. GVW trailer really needs tandem axles.

If you're carrying that much weight, consider buying a tandem axle kit with brakes and installing on your trailer. If your load is 3000 lbs., consider tandem axles without brakes--dependent on how demanding your geography is and how far you're towing.

See ChampionTrailers.com for the kits.

No springs on a torsion axle... kind of the whole point of having a torsion axle! :D

Agreed though, a 4200 trailer is USUALLY a tandem but there are some singles out there obviously. Is the axle free to move its entire stroke length? I've seen some torsions that were set up in such a way that it would contact the frame rails on a big bump, and it doesn't take that much of an impact with a load on it to start cracking welds.

I deleted my original reply as it did not provide an answer to the OP's question.
Based on the foregoing responses, here's mine!

I find a GVW of 4200#'s and an axle of 6000#'s for an aluminum single axle torsion bar sprung trailer hard to believe. I can only imagine the moment arm about the attachment point for the torsion bars. And, what rating tire would you use on such an axle? [Answered my own question: http://www.etrailer.com/dept-pg-Tires_and_Wheels-hs-Load_Range_D-gw-225|75~15.aspx. Kinda pricey things]

Checking myself I slid over to Wesco's parts site and looked up replacement axles and such. Currently Wesco list only twelve axles with a max. Rating of 3500#s. additionally, they only currently list leaf springs maxing out at 1750#s.

Maybe I'm missing sum'thin but I'm doubting the construction of this trailer.

The issue is it is aluminum, alot of people would disagree, but it does not stand up as well as a steel. (GA for GA)

The best thing I can think of is taking the axles off, weld the crack, then box it and reinforce the mounts.

Contact the manufacturer with the VIN, follow their lead as to original equipment pertaining to axle rating and brand they used for yours. I think you may learn something that belies the appearance ... ;)
