  • Remove the following eight screws securing the lower case to the chassis:

    • One 3 mm Phillips screw.

    • Three 13.5 mm Phillips screws.

    • Four 3.5 mm Phillips screws.

On my model, it seemed the top-left was 3.5mm and the bottom 4 were 3 mm.

Make sure you have a good quality Phillips screwdriver. Mine had removable tips and had a small play at the connection. As a result I didn't have a good feel and damaged my screws (those securing the fan and the top left in step 23). Game over for me installing new thermal paste...

Be very carefull with your screws! Especially those on the inside.

Carefully dislodge the edge of the trackpad closest to the keyboard from its recess in the upper case by pushing it away from the brackets attached to the upper case. De-route the trackpad cable through its slot cut into the upper case.

Immediately after step 12, it is possible to replace the two brackets that secure the upper edge of the trackpad in the top case of the MacBook (from which the six 1.4 mm Y0 tri-point screws were removed in step 10). My replacement trackpad was supplied with spare brackets, so I was able to replace one that was bent out of shape.

In the following steps, you will be working on your new upper case.
  • In the following steps, you will be working on your new upper case.

  • Use a Y1 Tri-wing 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.

Carefully insert the cable from your old trackpad through its slot cut into your new upper case. Use one hand to hold the trackpad cable in place as you insert the two retaining tabs on the outer edge of the trackpad under the lip on the upper case.

Insert a 1.4 mm Y0 Tri-wing screw into each of the outer holes drilled into the trackpad (two screws total).

  • Tighten the screws all the way, then back them out about a quarter turn to aid in aligning your trackpad during the next few steps.

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 Y1 Tri-wing 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.

  • Before reassembling your machine, verify that the set screw is still installed in a position so the mouse will click correctly.

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.

awesome instructions, thank you!

The Y0 bit included in the ifixit Pro Tool Kit was too large to remove the 6 screws holding the trackpad in place. Otherwise the guide was spot on.

please help me:

in the guide there are 6 "six 1.4 mm Y0 Tri-POINT screws " and 1 big " 1.2 mm Y1 Tri-WING screws "

but after some steps, the six triPOINT, become TRI-WING

so i don't understand: which tools should i buy to dismantle the trackpad?

ruben - Reply

If these are 1.4 mm Y0 Tri-POINT screws in step 10, I'll eat my hat. They are significantly smaller than the 1.2 mm Y1 Tri-WING screw (which is correct) at the bottom of the pad.

Moin,

mein Vorgänger sollte seinen Hut essen, derY0 Tri-Point passt einwandfrei!

Es ist eine großartige Anleitung, ich habe lediglich eine halbe Stunde benötigt!!! Vielen Dank!

Spot on guide. Thank you. Just used it to replace my trackpad.

Had to wait a month for a Y screwdriver though ... it was quite a bumper

If you have a Harbor Freight Tools near you, they carry a kit that includes the Y0 Tri-Point:

Great guide - took me about 25 minutes to replace my trackpad. I didn't follow step 13 as I simply kept the existing Y1 tri-point screw in place without any adjustment and the click felt fine. Routing the cable through the slot in step 14 requires a little care to avoid damage but isn't too tricky. At step 15, I noted that my trackpad was well aligned, so I replaced and fully tightened all of the screws and skipped steps 16 onwards, simply re-assembling all the other components in the order I took them out.
