Bucket seat track rocks.

[73chgrSE]

My passenger bucket seat has developed a little play in the track. It moves about an 1/8 inch or more on the right hand side. You can see from the front that the left side of the track looks to still has some kind of plastic or nylon layer that keeps the rollers firm and the right side track doesn't. Have any of you had this issue? Know of an easy fix?
