Ok, so I'm attempting to make a how-to installation guide for the Grillcraft Upper and Lower grill since "Grillcraft" did a really crappy job with theirs. What I have below isn't perfect (I missed a few minor steps), but if you use this in conjunction with Grillcrafts directions in the box or online
Upper Grill Instructions or
Lower Grill Instructions you can't go wrong. Some pics borrowed from Grillcraft because I forgot to take them while doing this today.
Step 1:
Take a before picture you start, because this is the last time you will ever see the old grill on your 4Runner.
NOTE: This modification is irreversible, you will cut up your old grill to insert the new grill. Again, this modification is irreversible!!!
Step 2:
Start by removing all the pop-down pins. Simply use a screwdriver to push down the center of them. Once you've pushed the center down, they pull right out as one piece. Now remove the plastic cover and set aside.
Step 3:
Once you've removed the plastic cover you will see a different style of black plastic pins. Simply use your fingernail to pull upwards and the pins will pull straight out.
Step 4:
Using a 10mm socket, remove the bolt attaching the grill to the radiator bracket.
Step 5:
Remove the 4 screws from the grill, you will only reuse the top two when you reinstall it.
Step 6:
This is the HARD part that everyone is having with removing the grill. Note the green and red circles in the images below. You MUST start with either the left or the right side GREEN circles. Using your STRONG THUMBS, lift on the tabs (they are the color painted tabs vice black tabs) and pull towards the front of the vehicle. Once you break the GREEN circle area tabs loose, you will then do the same thing for the RED circles. Lift and pull forward until you get all the way to the other side of the vehicle and you'll have one last GREEN circle area to tackle.
