    • Use a Tri-point screwdriver to loosely install the 1.2 mm set screw included with your new upper case into its tapped hole near the middle of the trackpad opening on your new upper case.

    • Only tighten it about one turn for now.

    • Before tightening, make sure that the trackpad is freely moving up and down. If you feel stiffness, try to very gently adjust it so that in its untightened position the lower part easily moves up and down.

    • While continually trying to click your trackpad, gently tighten the Tri-point set screw until the clicks return to their factory "feel".

    • You can tell when the screw is tightened just right by the noise it makes when the trackpad clicks. If the set screw is too loose, the trackpad will have excessive play before it clicks. If it is too tight, the trackpad will click too easily and won't make the characteristic loud mouse clicking noise.

  18. Next, flip your upper case over so the keyboard side is facing up.

The one thing I would be interested in: Where can I get the screwdriver this person is using in step 15? By this I am not referring to the low quality tools that are advertised alongside the tutorial.

--> can answer my own question. This is it: http://www.ifixit.com/Tools/Pro-Tech-Too...

Is there a key to getting the front edge of the trackpad (side away from the keyboard) to sit up flush with the body? The trackpad is slightly recessed at the front edge of the unibody, but nice and flush near the keyboard. Any suggestions are appreciated.

Before going to the trouble and expense of removing the trackpad make sure you don't just have a problem with the battery. My trackpad was giving me fits by not responding or needing excessive pressure, etc. The only problem was that the battery was swollen and putting pressure up on the trackpad. Replaced the battery and the problem was solved.

I agree with Rich M - check the battery first! Swollen battery will impede the trackpad.
