I have a 2008 Nissan Pathfinder SE and when you go over 40 & hit a bump in the road the car jumps/sways (not at slow speeds). New tires & balanced with full alignment. Suspension checked and 100%

I had the same problem on my 04 tj, if you have a lift or larger tires it happens frequently, they call it the "death wobble" buy steering stabilizers, there's one that replaces the factory one and there's another one that is supplemental and it goes a little bit below the stock one..... i got mine on quadratec.com for like $60 and i dont get any wobble anymore

Yep tie rod ends both control arms and a frame bushings. If you had time and could send some pictures I could be more presise and could give you a detaild ideal on how to test the entire front end, but you do not seem to want a lot of help as this would require me to give you two hours of instruction and testing parts that you are not aware of..

relace your shocks. the design of any dampner(strut or shock design) is to return the wheel to the road for handling and safety. when the shock is worn out is with continue to bounce like a basketball. it has no more strength to return to wheel to the road. a common misconception is that they are there to absorb, not true. the springs or torsion bars are there to absorb and create ride height. the shock does nothing more then return the wheel to the road. simple and inexpensive.
