If you are worried, and want to check your own car before you take it in, here's how.
-Run the front seat all the way back.
-Get yourself a very powerful flashlight.
-Find the front of the two front seat rails. The weld affected is right under the threaded rod in the seat track. It starts about 1 inch rearward from the mounting bracket for the threaded rod.
-You might have to wipe some of the grease in that area away to see the weld.
- The weld should be a square "U" shape with one side longer than the other.
-Make sure the weld looks smooth and nice with no skips or gaps. No missing metal from the weld.
-Any missing metal or skips or gaps requires a new seat rail frame.
