There have been some recent threads that include links to sites with instructions. But it is easy. You'll need either gripping solvent or white spirit. Process:
1. Remove old grip and any remaining tape.
2. Place tape on the shaft. Length needs to be just shorter than the grip (= stating the bleeding obvious). Fold any excess into the end of the shaft.
3. Use a paintbrush to apply solvent liberally to the tape. Do this about 60 seconds before putting the grip on - it activates the tape and makes it well slippery and thus much easier to push the grip on.
4. Use the 60 seconds to stick a tee into the small hole in the butt-end of the grip and then pour a decent amount of solvent down the grip. Use your finger to seal the grip and up-end the grip several times to coat the inside of the grip (now you know what that little hole in the butt-end of the grip is for!)
5. Pour out the excess solvent from the grip and remove the tee.
6. Slide the grip down the shaft. Something to hold the club steady helps. I find a standard Work-Mate bench with the plastic grip-lugs is fine and doesn't cause damage/scratching of the shaft. Watch out for solvent squirting out of the end of the grip (some people leave the tee in, but it causes some pressure build up and thus resitance to pushing the grip on)
7. Once the grip is fully on, turn it so that the decals/logos are correctly aligned
8. Leave the club upside-down for 24 hours to dry, permitting excess solvent to drip out. If the grip is still greasy with solvent after 24h, use some hot water to wash it off
EASY!
