    Getting ready to install refurbished wishbones...

    The "screws" #182215 are an interference fit on the lower wishbone flanblocs but I don't see in the wsm how they are removed from the old or inserted into the new. Are they pressed out? Can they be re-used? If new screws are used does tightening torque pull them into position or do you press them into position?

    I just did this on my 360CS and the screws looked identical. For dissassembly i used penetrating oil and a punch which was slightly smaller than the diameter of the threads and carefully tapped them out. Then I cleaned and inspected the screws. For assembly, i used a custom sleeve (made on a lathe), two washers and a nut.

    Worked really smoothly. I did install into challenge flamblocs, which seem to be a different material however, so ymmv.

    Finally got the parts and the time to attack the front suspension - changed both wishbones (new balljoints and flanblocs) and the droplinks after having changed the tie-rod ends a few weeks ago.

    The components on the upper wishbone showed the most wear. The flanbloc closet to the front on both sides was heavily worn (nearly destroyed). It seems this component suffers the most in the 612 suspension. The lower flanblocs were still serviceable which surprised me. Both upper and lower balljoints had significant play, but after 167,000 kms I wouldnt expect much else.
