Because the old ones are rusted pieces of shite that have been partially rounded off by whoever changed the fluid last time. The next time I change it I'd like to have new ones on hand to swap in.While I'd like to save harm to your laptop I do wonder why you'd need to know. They generally don't go bad.
Thank you!Here you go:

You can also use a 18 x 1.5 bolt for the rear differntial fill bolt. These are easier to remove and it is also the same size for the transmision drain bolt. Dorman 65220 hex bolt will fit the rear differential fill bolt in place of the normal Toyota bolt.
To remove the transfer case fill bolt I use a allen key and cut it to 1/2 inch wide and then fit a metal tubing (12 in) to make it longer. This will allow you fit your tool in that very tight area where normal tools will not fit.
The rear differential is exposed more to road salt in some regions causing severe rust in the fill and drain bolts. Clean off the rust with a wire brush or what have you and tap the allen socket with a hammer. This prevent rounding the inside of the allen bolt. Using a 2 inch socket extension will help clear the exhaust pipe in the way.
