Driving a 2011 with manual car seats. You know that sound when you adjust the seat forward or backward? I'm getting a similar sound when I'm not adjusting the seat. Usually happens when I accelerate from a stop or brake, and it is only coming from the right side. Any idea what the problem could be? Suggestions for a fix? Thank you everyone.

 

I just picked up a 2009 Sport MT and the front right bolt holding the drivers seat was quite loose. If you can rock the seat a bit, this may be the problem.
