I got a built 350 in my 40 and when I let a friend drive up some hills I noticed the axle rolling more than I like when he got on it. Need to build anti wrap bar and was looking for some good pics of how you guys mounted yours. Thanks
Need pics of anti axle wrap bar

You will get a few pics just make sure you brace it where you join it to the axel real well or it will rip off.

Dargreg, I was thinking the bar was to keep the axle stationary, but looking at you front brace the axle can still rotate? Like a piviot. Or is it fixed.
When you are going through ditches and such your Axel is going up and down and twisting ,It will not come forward or backwards to rotate as it looks.There is many ways to accomplish this I used hi ems joints and shock ends.I,ve since straightened the single end so its more straight up and down.

I knew it had to be able to pivot up and down, it just looked with the dogbone shaped joint it might rotate when in rev. thanks for the pics.
One thing to remember when you build ,If you think its strong enough its not.There is a tremendous amount of force there.Use thick walled tubing and a minimum of 3/16 plate for the Axel.

Man, that is nice.
If that goes missing one night, you know where to start looking!

Still learning about fj's. But why does one need these. I have a 69 fj 40 stock, is it something I will need to do if my plans are to leave it stock? Thanks for any info.
Anti wrap bars are used to prevent the axle housing from wrapping the springs up, that is making them look like a S rather than the normal arch they should be.. When the springs wrap, the axle housing rotates, as this happens the pinion points toward the sky.. When the pinion points too far to the sky, the drive shaft universal joint can bind and cause pinion breakage.. Spring wrap is more of a problem in SOA applications than SUA.. Anti wrap bars help get driving forces to the ground better too..
Here's a good one.
i have a write up on mine if you need to as well,

Hot Damn
You only need one of these for sprung over trucks. If you are gonna leave it stock or lift it sprung under then you'll be fine.

Ok , lots of good ideas, everyone seems to have welded the brace as close to the housing as possible. will the front factory cross brace be strong enough for the front attachment point ?
I must have been unlucky then, because mine is still sprung under & I destroyed a set of rear leaves on mine. Had to drive it 100k's home with the damn thing vibrating all the way due to the angle that the rear pinion was on.
You,ll have to check your spring purchases to see if they have been rounded off ,Only way you can break leafs on the spring under.
Yeah I wouldn't count on the stock cross member. You may want to build a more stout one. Don't know where my pics went
