Re: 99 SHO - control arm replacment questions

i've described it several times, and i had a good shop look at it, and that's gotten me down $100 and not fixed so i feel my personal diagnosis is as good as any at this point.
I've also discussed it at shoforum and taurusclub.
I'm much more concerned w/the replacement procedure.

Tr's and bj's were done for prev maint, not due to the noise.

But since you asked...It's basically a loud pop. It originated all at once when i hit a big bump in a construction zone (overlay). At the time i thought an end link broke, that's the type of clank it made.
It is most easily reproduced by braking and accelerating quickly. But if i brake once and make it pop, i can't brake again and make it pop until it pops in the direction of accel. Make any sense?
I made my personal diagnosis by having an asst. roll it fwd a ft and hit the brake, then back a foot. It pops in both directions. EVentually i reached through the wheel well so i could feel the lca during the pop and i thought i felt it shift.

I already have the new lca w/bushings which was <$50. Worst case is it's not the prob and i've eliminated another possibility.

Fwiw, spring is fine, strut mount looks solid.
Sway bar bushings aren't in great cond, but they're not making any noise.
I've also dealt with and repaired a sub-frame bushing pop recently. This isn't that.
