I have a vibration at 50mph. the steering wheel moves side to side. Wheels are balanced, rotors are true. continues even after the tires are hot.

Alignment would cause that. Also if you threw a wheel weight due to interference

with the caliper. Also a bent rim (you can balance a brick, but it's still a brick).

Rotate the tires front-rear and drive again. if it moves to the rear, it's tire/wheel

problems.

If it stays, then I'd look at suspension. Look for bent/loose items, and worn bushings

& tie rod ends.



but before you start anything, take a torque wrench and torque the lugs (nuts/bolts)

to 80-90 ftlbs. it could be a loose wheel too.

Thats your answer in a nut-shell.



All the problems I've ever had with shuddering at higher speeds was tyre problems. Hows the tread looking on all the tyres? Uneven tread can cause problems.
