the diagnosis is 100% believable and checkable, but likely correct on a heavy car with high mileage and harsh conditions. The charge from a dealer is obviously atrocious and as mentioned above a charge for quick bolt-on of a new part vs a repair of existing (remove and reinsert aftermarket bushing)... Your choices are a) Eat it at the dealer, it's not totally insane in today's world b)Get it fixed elsewhere for possibly less money but maybe not much less with labor at $200 an hour nowadays or...c) try an alignment only shop see if anyone lied (but you risk wasting your time there too, bushings are probably shot) or...d) do trade in (elsewhere) if you are serious...

Sometimes we do not have the time for the cheapest solution.

similarly Wife's Q7 needed new engine mounts (fluid filled and electric connector!!!) dealer wanted $4000, indy did it for $1600. it was twice the hassle and more time and some after repair revisit (steering was no longer centered, needed reprogramming). In that case the $2400 diff made the hassle OK. Other times it is not worth your time and I suspect you are not gonna save a ton here (taking control arms out and taking bushings out and putting aftermarket ones back on, reassembly, labor, meh)
