Changed tension strut bushings on wife's x over the weekend what a chore. Impossibly rusted in parts.
A couple tips for somebody that has to do the same:
1) just buy complete arms with bushings.
2) see photos how I was able to use impact tool to remove the bolts
3) not terribly difficult to lower the truck to tighten the bolt. Better than try to guess how far to lift the rotor and hope you don't lift the truck off the jack stands
4) the ball joint will spin when you try to reattach the wheel side, use a hex wrench to hold the ball from spinning when you tighten that bolt. See 3rd pic.
I removed the few screws that held the inside of the fender so I could access the big bolt with a couple wobble bits.
The right side had an air duct that I loosened as well the left side didn't.
