Outer Limits 4x4 Board

Any have any knowlege on the GU steering boxes? Ie How tough they are, when u might see signs it might need to be looked at for re-conditioning etc etc.

I don't no alot about them but all i can say mines been through 6 comps turns 37's on the spot when need be so i would rate them pretty good. Like anything keep the fluid up to them and check for signs of wear and tear.
