Suspension movement when I pull on tire

[Jordandixie]

Hey there so I have a 96 gmc 4x4 replaced the upper ball joints, outter and inner tie rod ends , and the upper control arm bushings . I need to replace the sway bar linkage on passenger side as it broke off. I noticed my tire is leaking in a bit , when I grab tire (not jacked up) and move it back and fourth the whole suspension moves upper and lower control arms go up and down , would the sway bar linkage stop this movement ? Or is it something else?

Check the idler arm or pitman arm.
