Adjustable control arms.
 

Alright im a newbie to adj. control arms and i have a dumb question. When the jeep is flexing how does the jam nut not come loose? I know when it tries to articulate to one side it will act like tightening the jam nut but flex the other way how does the jam nut not come loose?

I didn't know that there was any rotational forces acting on the control arms. :thinking:

The sperical joint should be doing all the rotating. This should have enough play in it to not let the jam nuts get loose.

Maybe im thinking to hard about it but when theres articulation theres twisting in the suspension components, hence the use of heim joints, johny joints. They allow more articulation by increasing the travel of the joint, stock bushings bind at a certain degree. my question was wats stoping the arm from twisting to much and loosening the jam nut.

Please feel free to correct me i often over think things.

Thats what i thought but didn't know if it could ever come loose, but then again ill probably never max out the joint.

Yeah I think its a combination of things. The Bump stopts to keep you from articulating to much upward and the limiting straps and or shock length for limiting the down travel. I would assume that if none of these were used or you had the wrong equipment paird up you do run the possibility of either tightening or loosening the jam nuts.

Thanks! :)

They all bind against the control arm bracket. Some more than others. They can't twist too much. There is no where near enough force a properly torqued jam nut loose. You can't even adjust them (most arms) while on the vehicle. You're going to over load your brain bro ..be careful. We don't want a repeat of 2008.

Ya i know My brains wound tight, ME classes are driving me crazy this semester...

Check out Metal Cloak video on their control arms, they flex about 78 degrees sideways.
