Well I pretty much chewed up the little bitty ball bearings that are inside of my auto locking hubs,'90 'burb 4x4 by the way, and I was thinking of replacing the auto hubs with manual locking hubs, yes I know all yhe advantages of auto locking hubs but from what I have gathered talking to some hard core off roaders manual locks are much stronger and more reliable. Heres my question can I put manuals in place of my autos and will that screw anything up?
