front wobble at 50 -58 mph

So my last trip to Gulches I did a decent amount of damage. I bent a rear axleshaft, broke a front brake line, scraped the balancing weights off my tires, busted my winch cable, etc. Since then I've had lots of wobble. I've replaced the rear axle shafts with chromolys, rebalanced tire, rotated the tires, adjusted the alignment, checked the steering components, replaced the ball joints.

Everything is gone accept a speed sensitive wobble from roughly 50 - 58 mph. What am I missing? The only thing I can think of is the Unit bearing... is there a way to test it?

Any suggestions on what else to check?

most speed related issues are tire related. Check your toe in the front. Maybe try unrotating your tires.....?

I should add: 3" tf lift.

The wobble was much worse before the rotation and balance. thats why I'm thinking its something eles... I was really hoping the rebalance adn rotation would solve it.

What should toe be set at? I measure at about 1/8" but I want to double check it.

I would guess it is your tires out of balance. I rotated mine about 2k miles ago. And now have a slight wobble between 50 and 60mph. Never had it before I rotated them. I'm just living with it till I rotate them back in another 1k.

Might you have a bent c or something? Camber being far enough out of spec will cause a steering wheel shimmy. That is what causes the one I have. Just waiting on a new axle to fix it.
