Grizzly pulls to one side.
 

tyre pressures are right and nothing is bent or loose. How do you adjust the alignment on these things ?
Also please confirm the following terms :

Toe in: is like the front wheels are tracking towards each other
Toe out : is like the wheels are tracking away from each other
camber: is like tilting the top of the wheel inwards ( negative) or outwards ( positive)
castor : ?

Thanks

Chamber and caster are fixed solidly, and cant be adjusted.
Have you had any crashes or rough slamming on the front end?
Toe is the only adjustment, and adjusting the tie rod ends, is what will make them toe in or out. And you can think of it as being pigeon toed for toe in, and bow legged for toe out.
You have chamber right, and castor is how much the tire leads or lags the pivot point.
