I'm no car expert, so i cant self diagnose the problem. My 2002 TL-S has a problem it has a slight vibration at 50 mph, but once going past 60 it gets pretty shaky and it scares the shit out of me. My first thought was alignment, but i have no idea. Suggestions?

 

Wheel balance probably first place to look

 

Your TL is older than mine so its possible you have the same issue as mine.

Welcome AdumJens !!!

Shaking in a 10 year old car with perhaps a 100k worth of driving can be the result of normal wear and tear. Many things can cause this shaking sensation. As MarcDavidoff previously mentioned it could be something as simple as the tires needing balanced or rotated ? Easy enough to try.

Your best bet would be to take the car to a good alignment shop and have them evaluate the issue. They could check all the common things such as tires, brakes, suspension and steering components. Ask them for an itemized estimate for repairs and get a second opinion if the expense seems unreasonable.

 

If its not you tires then axles or tie rods.

 

Yeah another fun possibility, if you have alloys, is that they might be out of round.

 

...or even the tires !!!
