Im sorry for the confusing there are in fact two bearings in there I just got confused with the two different hub types.. I will try and get pictures up tomorrow, I still cant figure out why the drum is wobbling.. But Ive been wanting to put disks on the rear of the truck for the longest time now, So my plan is buy two hub rebuild kits with disk brakes....just sucks I cant figure out why they are wobbling almost like the axles are bent not sure hopefully the rebuild kit will do the job
