How would this negatively affect the scrub and cause bearing problems. Spacers are a used often and the extended hubs on stock axles change scrub and I haven't heard about abnormal bearing wear.
So far the lady that drives the 1 ton we put these on says it drives and handle perfectly, in and out of parking and highway driving no issues I have the truck back in the shop for a 500 mile check and the tire don't show any abnormal wear.
