I'm giving my dad a ride from the airport and while on the highway i hit a small divot in the road and my front end began to violently shake and only subsided once i let off the gas. Trying to brake made it worse. My front-passenger tire is extremely worn on the outer edge as well. The local mechanic was claiming i need new upper and lower control arms as well as a sway bar and some other mounts and bushings as well. Can anyone who's experienced something similar confirm this? The mechanic didn't give me a number but said it would be pricey and needed to be fixed soon.
