Can you swap the disco to the other side of the swaybar & bracket?
It's no different from running the equivalent offset rims, which people also do all the time. I would think the increase in weight from larger tires would have more of an impact on the total torque on the bearing than just scooching it out more but I haven't done the math on that. If the increase from a bit of a change in offset actually made the difference in whether the bearing lived or died then that bearing wasn't going to survive much more than stock wheels and tires.Really? Not sure about this..wheel spacers add an additional length lever arm that will exert more force on the bearings than if the wheels are closer to the bearing.
That extra force may be more than the axial loads the bearing was chosen for.
