When driving My Solara over 65-70 mph steering wheel shakes badly VERY BAD Why? on 1999 Toyota Solara

Also when I am going around a curve it actually seems like the front tires on both sides are shaking to the point I have to slow down when braking the steering wheel shakes badly as well it happened after I had 4 wheel alignment as well as wheel balance and tire rotation done it got worse what could be wrong PLEASE HELP?????

Have the suspension and wheel bearings re checked for play or a bad/out of balance tire or rim. If you experience the steering wheel vibrating on braking it sounds like the brake rotors may be warped and need to be re-machined or replaced. It shouldn't be hard to properly diagnose what is wrong.

Agree with patrick. The parts most likely to have an issue is the ball joints or tie rods. They go bad and your tire will 'wobble' all the time.
