this drill is a pain the proverbial butt, drill bit falls out on stopping, read a few disgruntled owners have the same problem, so what im going to attempt is a new chuck, but not one from hitachi, something better, iv seen a few but im uncertain if this one will fit, 105118A Professional 13MM Keyless Impact hammer Drill Chuck W/ Lock SDS Adaptor
does anyone know..

Why not ask on the Amazon Q & A page where you are getting it from?

I think that to take it off you need to open the jaws and remove the screw down the throat of the chuck and it might be a reverse thread so undo clockwise. You have to unscrew the whole chuck off the driveshaft and to do this you need leverage. You can use a socket set on the bit holder tightened in the chuck and give it a good whack to loosen, I think it turns off clockwise. Your question about the replacement compatibility will depend on the spindle thread size.

You will not know until you take off the existing chuck.

i got specs from hitachi, but the 1/22 seems odd, should it not be 1/2?

Diameter (Non threaded) 10mm
Square End - 8.25mm
