Front suspension questions
 

Hey all, my tie rod ball joints are cracked and so are my CV boots. I've been hesitant to do suspension work on my X since 2021ish when I sheared off the eccentric bolt alignment tab in the back and had a shop re-weld it. BUT now I'm wanting to get a bit deeper and conquer my fears.
I've watched a lot of videos where people, namely M539 on youtube, use ball joint (I think) and bushing extraction tools.

On RealOEM the front tension struts:
31126769717 (L)
31126769718 (R)
have listed:
2x 31126769715 (Tension Strut Bushing)
2x 31126756491 (Ball Joint)
as components that seem to be replaceable.

The FCP kit from Lemforder: E53CAKIT10PIECEL has both tension struts with bushings preinstalled, and the ball joints separate.

Same with the front wishbones:
31126760275 (L)
31126760276 (R)
have listed:
2x 31121124622 (Bushing)

Both are the tension strut and wishbones are sold in the kit as the complete assembly.

Can or should I purchase the two replaceable components for the tension strut? Are there reasons to do the whole assembly over the serviceable parts? One time a shop told me you can only do replacements of some of those serviceable parts about two times. I'm not sure if that's true or not and I can't recall the reasons they supplied to me, so I wonder that also.

My CV boots are covered under a shop warranty so I'm gonna have those serviced and then start a refresh sometime soon (probably with x5chemist unless I get excited and jump the gun).
