Steering wheel shakes and vibrates

Question

whats going on with my car. my steering wheel is shaking when i go over 45mph.

Answer 1

Its feedback from the rack+pinion system.

Your suspension may be out of tune and sending to much back to the steering system.

The steering is power assisted by the way, its not a joystick like drive-by-wire.

Also, make sure the power steering fluid is full and the compressor is working right...

Answer 2

this happened to a previous car my other half had...it turned out to be a suspension leg had moved ever so slightly..which was easily fixed...infact he done it himself but id advise paying a small amount and gettin a garage or mechanic to do it...always better to be on the safe side when it comes to cars.

Answer 3

First check your air pressure in your tires.  Inside the drivers side door sill it will tell you the correct pressure.  It's almost free to do so start there.  If that doesn't fix it, get the wheels balanced.  Weight can fall off so it might be the problem.  It will cost you a little but it's pretty cheap so that would be next.  If not that then an alignment would be the next thing I try.  If none of those work than it could be something ring with your suspension system but I'm guessing one of the first three things will fix a vibration.

Answer 4

I suspect your wheels need to be balanced.

Answer 5

I'd start with the cheapest cost first,

Check you tires...make sure they are well rounded and that your wheels have to warps or bumps either...

Check air pressure...

Have your wheels/tires balanced [usually suspect of vibration/shakes at higher speeds]

If your steering wheel pulls to any one side whiel driving, get an aligment done.
