I'm deciding whether to go with 4.56's or 4.88's on my FJ40, using an ARB locker.

How much weaker are the 4.88's than the 4.56's from a practical standpoint, especially given you have to grind the 4.88 ring gear to fit the ARB. Breakage is usually at the pinion?

In practice will the 4.88's have a much greater liklihood of breakage.

The only grinding you have to do is to the ring gear to fit the cross pin in, and it is not much. I loved my 4.88, and would do it again. Yes the weak point is the pinon.

build a sweet traction bar and the pinion shoudl last u! jIMMy

Jimmy is right, when the pinon angle starts to move the chances of breaking are increased.
