    I've read lots about the crossover steering conversions everyone is doing, and they do seem to make sense. I've been in situations in snow coming over sharp rises where the front axle would drop away, the tires would turn despite a lack of steering wheel movement, and I'd go sliding off the trail. Took me a few times to realize to steer the opposite way like a madman and then correct when the weight fell back on to the axle.

    Anyway, on to my question. The factory steering setup pushes and pulls the axle (through the steering arm) front to back, which I believe is the strongest plane for a leaf spring suspension. Cross over steering pushes and pulls laterally, not as strong for these suspensions (I would imagine, especially at full droop). I know Ford Super Duty's have leaf spring fronts, and they use a link (I think it's called a Panhard) to laterally locate the axle under the truck, because of their essentially crossover steering system. Has anyone experienced any unwanted side effects from a lack of a panhard, or would it just cause the suspension to bind?

    The panhard is there because the leaf springs are so soft that they wanted to make sure that there isn't an axle location problem laterally.

    It should not be necessary on your truck, especially if it's lifted. Lifted trucks have stiffer springs, so you definintely shouldn't have to worry about the axle moving laterally any more than what the bushings will allow.

    It's less radius with the stock set up so you get more push pull on the short drag link. When your at full droop the box maxes before you get full steering and the tierod ends can bind. So the steering is less effected with the cross over.
    Yes your correct it can cause some side to side motion of the axle but it's minimal. Your pushing against the flat of the spring so it takes quite a lot of lateral force to cause movement. When flexed it would take less but your in a slow speed situation then so very predicatable and easily compinsated for when steering. Yes a Panhard would make it better but the set up is still better than stock EXCEPT you can't run a factory sway bar. Most of us that do heavy trail riding just live without the bar.
    I pull trailers a lot with mine and I want to retain the bar for the stability. I'm trying to figure out a way to run a bar and cross over.

    I don't need no damn shop manual, I got a pornographic memory.

    Grim,
    When you figure out the xover/swaybar dilema, let us all know, please. [​IMG]

    No problem I will. There is some bars for dragsters that might work but need to see if they are strong enough for a K5. They have drop down links so may be able to work without hitting the drag link. Also looking at a Bar made for the newer Jeeps. They have a simular set up. Again it will be enough strength to handle a K5 issue.

    sway away makes custom bars for EVERY thing.
    it would be so simple to put a different bar in.
    the bar is just flat no needed.
    for towing you would be better off getting a REAR bar

    Anyone ever seen the Ford Super Duty sway bar? It's BEHIND the axle. Kind of cool actually.

    yeah, it might be cool if it didn't hang 5 inches off the ground!
