my steering wheel just recently keeps on shaking when ever I hit the 100 km mark. I took my Z to 3 different alignment shop already but nothing happened. has any of the members here experience this problem?

 

Just a suggestion. Put a subject in the subject line like

Squeaking brakes

instead of

Help

Need help immediately

or

If you don't help right away I will die!

 

^ What he said.

More likely to find help that way.

 

have u hit a pothole resently...u might have bent or broken something an it not visible...make the alignment shop get it right which should of been done b 4 u paid....

 

Bad alignment, worn-out tires, out-of-balance tires, bent or loose suspension components. Could be quite a few different things. Take to a shop that knows cars, not just tires and alignments.
I've had the same thing happen at about the same speed when driving on badly worn tires on different cars. Could be as simple as getting new tires.

 

+1 bought a pair of used tires once. Had plenty of thread left, but the non visible belts on inner side were broke. Caused my car to shake at certain speeds.


Also, have your tire balanced, maybe simple as a weight falling off.
