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.



Raul

yeah what he said



mike

check the sway bar end links

What about wheel bearings, they could be worn

ohhh im gonna do that to my malibu too i got vibration at 60-75

Well have you been driving when sudenly your car drops and you see your wheel drive on

I have left hand front wheel. https://www.nopistons.com/forums/pub...1047683785.gif

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.

maybe a bent drive shaft??
