I recently started experiencing a bad shaking from my steering wheel. I bought new front rotors and brakes and installed them. The car was better till like 2 months later and the problem is getting worse. I also feel like I'm all over the place when I'm in the highway doing above 50mph. Could it be my alignment or is it more serious than that. Any suggestions will be extremely appreciated. Thanks.

 

My first guess would be a tire balance issue.

Take your TL into a tire shop and get the tires balanced. You can get this service free if the tires were purchased with free lifetime rotation and balancing.

Also check your tires for the proper inflation pressures and do a visual check for any damage or unusual wear patterns.

Have the tires balanced and make sure the lugs are on tight.

 

It's either lugnuts, balance, or alignment.. c'mon dude.
