Did you make or buy the  radius arm brackets on the front end.if you bought them were at

So after some serial abuse I managed to break one of my front radius arms in half and my rear locker decided to crap the bed. I'm not sure how DOM breaks like this but maybe someone has seen this type of break before. On the lighter side I did manage to dig up some video from last years campout with my son driving.

nanton 2010 mike's video - Powell River

It looks like it ripped where it was flared out.

This break is in the middle of a length of tubing with no signs of an old crack

DOM isn't a special tubing, it is mild steel electrically welded and drawn
over a mandrel to remove the inner seam, but it isn't special voodoo proof
tubing, just heavy wall, and subject to fatigue and cracking like any other
tubing.

You may of had a stress flex spot there that worked it to it's breaking point,
it looks to have a good amount of corrosion both inside and out, so I wonder
how long has it been in service and not protected with a coat of paint?

Now if you had these made out of chromoly steel tubing, that stuff is more
or less voodoo proof and would probably hold up better, but requires special
welding techniques to stress relieve the weld site, not as user friendly as DOM

Some video, that was awesome video, I love that kind of wheeling.

Thanks for posting

These have approx 3500 kms on them since I built the truck or 2 years, I painted everything when I built it but not the inside. I'm sorry you had to suffer through that video but that's the only kind of wheeling we have around here

For the inside you can get that creeping oil, you shoot it down inside to the
welded end and then weld the last part, it will creep around inside and help
prevent corrosion, you should be able to get it from air craft supply like Spruce
Aircraft Specialty

Oh, I enjoyed the vid, I would not of watched all 12 min if it was boring

Wild,

isn't that weld spatter visiable in the second pic?

Might be a little from the upper link intersection which is farther forward

Great Vid, looks like a tricky section but serious fun. Oh, and Wild , it's more like 13 minutes 

great looking cage. im hoping to get mine done over the winter but have mine open to use the back passenger doors.

Awesome bulks! Video?
