This is kind of a picky thing, but I recently purchased an 05 Durango Limited, and am now noticing the driver's seat moves a very very slight amount. This can be felt when accelerating and braking. It can't be moving more than a millimeter maybe, but it is still bothering me. I can also usually hear it, as a very slight click.

Is this something I can fix myself, or is it just normal after some wear on the vehicle. It is great condition, with 35,000 miles. Any tips would be great! Thanks!!
