When to change rear control arms?

[Speed 330]

You're not alone with being frustrated at the sloppy suspension. I have a 2011 with 91k miles and it handles like crap. I just replaced the springs and shocks/struts on all 4 wheels along with the sway bar bushings and stab link bars. That helped quite a bit, but it's still loose. Not sure if the next step is to replace the upper/lower control arms all around. Are there any other bushings I should be aware of that would affect ride quality?

I changed everything up front I bought me some really good Springs from ground force I got that Bilstein shock all the way around thing rides great upper and lower a arm bushings ball joint upgraded to sway bar from Ford same in the rear Raj real good
