Gu steering box in a Gq

What are the advantages of a Gu steering box in a Gq can they be changed over ?

It's a bigger stronger box. You will need the drag link or or at least the tie rod end off the GU too as the taper is different.

I haven't had issues with my Gq box so far it is just that the wreckers offered me one and now would be a good time to do it as I am upgrading my lift kit and I can get the connection new to the box
