Thanks for the reply laduno!
The bearings can be slid off the end of the axles after the wheels, and 3 bolts are removed from the flanges that hold the bearings to the hangers but the hangers ARE 1 solid piece without any slots in them, Just a big square with a hole in the center just big enough for the bearings.?!!
NO way the sprocket or brake disc hub will fit through em. They are a cross shape with a bolt in the end of each "arm". I quess cutting a section for the axle to drop through may work but Im not sure it if will weaken the hanger or cause the bearing to not want to stay seated.? I am a cert. welder and have a mig so welding is no biggie, but just thought there had to be a better way, maybe!! LOL.
