That would help if the nut is stuck on the bolt and the bolt free-spins in the housing. He has the opposite problem. The nut is off. The bolt is stuck in the housing. He'll need to push the bolt out while turning it with the impact.

Ah, I see he can't get the bolt that affixes the link to the strut/spindle.
Use a ball joint press or a c-clamp. Put a socket on the one side to give an area of recess and a punch on the other end to drive it through.
Air hammer helps.
I suggested the ball joint press, but I like the C-clamp and socket idea better!
