the steering wheel sometimes shakes at high speeds around 70 miles per hour. It does not always happen. Some day when I am driving at 70, I feel no shakes. some day it shakes badly at the same speed. Also, if I drive slower or faster a speed range (usually between 68 and 75), it never shakes.
I did the following, but still the wheel shakes sometimes:
- I had the left wheel bearing replaced a month ago. The mechanic told me it needs to be replaced.
- Tires are fine (not perfect, but not bad either). I had them rotated a month ago.
- I had the front rotars and pads replaced a month ago. When I brake, it does NOT shake.
This shaking wheel problem has been around for quite some time (almost two years). What service does the car need?
Update: I had the tires balanced, and it is a little bit better now. It is not perfect yet. I was told that the tires are kinda cheap, low quality tires that are not perfectly round.
