What are the full open (usable) dimension of the gear wrench?

it says 2 and 1/8th inch in the ad for it

Any idea if this will work on a 2001 corolla?The ball joint is right next to the cv boot and i want to not damage it.

Had similar issue on 2003 corolla, leave nut flushed on bolt for stability, spray silicone on separator to lubricate and slide between nut and boot, if all fails, disconnect the 2 nuts and 1 bolt for the ball joint base, remove knuckle and then use seprator.

Does anyone know the jaw size?

The slot is 7/8" wide by 1-1/4" deep. Completely extended the "jaws" open to 2-1/4". I've used on VW beetles and other small cars with great success.

What size is the bolt on the tool?

Sam, the size of the bolt on this tool is 15/16. It's a great tool and easy to use. Good luck.
