Hi everybody. I've coming out of long-time lurk mode cuz I got a question on my newly SOA'd FJ40.
Watching the pinion when you get on it is kinda comical, but I'm afraid of what's gonna happen so I'm about to fab a traction bar sorta like Woody describes at
http://www.ih8mud.com/tech/woody/wrap.html
Anyway, since the rear springs are reversed, the pinion drops in an arc as the axle droops (since the short/stiffer spring side is to the rear), while a 3pt traction bar wants to move the pinion up in the opposite arc (about the bar's shackle mount). I imagine this binds/limits travel/causes stress/is generally undesirable.
I'm trying to visualize different mounting points, or else two unequal arms, or maybe a single arm w/ a lower front mount... not arriving at anything I like though.
Any thoughts from those that have this specific setup... have you found a geometry that will allow "harmonious" movement? Or did ya just build one & run it (that is: does it not limit/bind that bad in reality)?
Thanks! -Ed '70FJ40
