Not specific to your application but I often worry about the strength of hubs on hot rod and component car applications. Most of the time rear ends are narrowed and have different offset wheels to what they were originally equiped with.

The center of the tyre tread is roughly where most of the force generated by your engine and brakes ends up being transmitted to the road. As your suspension moves and cornering loads are added this can move anywhere across the width of the tyre. Most factory rear suspensions are designed so the center of the tyre is roughly inline with the axle bearing. The bending stress these forces have on the bearing and hub is kept to a minimum by keeping them close to the pivot point. By putting this rear end in a component car and adding some big sticky tires on rims with a big offset length of the lever is increased dramatically. Then add an engine that makes much more HP than the original car did, bigger brakes etc.

I'm surprised we don't hear more stories of people breaking hubs and carriers. I guess the over engineering car manufacturers have to add in to make their cars last in harsh conditions (pot holes, rough roads, women drivers etc) is saving our bacon.
