What causes severe vibration to occur after 30 minutes at 70 mph?

Asked by Jul 22, 2015 at 04:00 PM about the 2005 Saab 9-3 Linear

Question type: Maintenance & Repair

I have a 2005 Saab 93 with about 58000 miles. It has suddenly developed a severe vibration after driving above 65 mph for more that 30 minutes. The vibration seems to originate in the front end (the steering wheel moves violently from side to side) and does not go away until the car is below 30 mph.

If I turn the car off for about 15 minutes, the vibration goes away and does not recur unless I drive over 65 for 30 minutes or more.  

Local driving (below 60 mph) does not cause a problem.

This just started within the last few months. Prior to this, I drove the car to work 50 miles every day for more than a year on an Interstate highway where normal traffic flow was about 70 to 80 mph.  No problems.

What could be causing the problem?

You could have warped rotors, warped pads, front wheels may need a high speed wheel alignment.

I would check the wheel bearings, or CVT joints. I can't believe how this is a brake issue. Possibly a wheel problem, but, in any case, you don't want to fool around with front end problems as it could cause an accident. Good luck.

Sounds like you need to have your tires balanced.
