First - I have to say *!Don't try this at home!* Unless of course you want to, and are willing to take full responsibility for your actions! That's my CYA - statement. With that said here is what I did: Ordered/received the parts from Nikon (I got an extra set JIC). Fig 1 and 3 Gathered my tools, flash light, precision phillips head screw driver and "optional" wire cutters. Fig.2 Peeled back the rubber grip material from the bottom only and removed 6 screws from the base. One is hidden under the Nikon sticker. Fig. 4 Unscrewed the 4 screws that hold the "tower" on the top which will expose two more screws that hold the top and bottom halves together. Fig. 5 After I unscrewed the 2 shiny screws I put the "tower" back on with 2 screws "loose" just to hold it in place so not to put to much stress on the wire connections. While looking close at the wire positions, separated the top and bottom halves of the grip. Found the 4 screws that hold the "battery box" together and unscrewed. Fig. 6 Only 2 screws left, if you are replacing both hooks. I did not unscrew completely, just enough to remove the hook and small spring. Noted the orientation and replaces with new hooks. Fig. 7 and 8 All finished with that once I put the 18 screws back in!! OPTIONAL procedure - I used the wire cutters to trim off a couple of turns of the battery springs. Fig. 7 and 8 The batteries put very little pressure on the hooks now and will hopefully not be taking as much abuse as the previous design. I always hate when I see RR - which of course means reverse of removal. In other words put it back together!! I did not need to use any glue for the rubber grip material, YET! I just pushed it back on and it is holding. I'm sure it will not hold with constant use so I plan to use contact cement in strategic places - in other words, not in the seem between top and bottom halves in case I have to replace the hooks again. Hope not, but no harm in a little fore thought!!
I did take several more photos but of course I reached the upload limit - so, here you go. Feel free to ask any questions, Dave
