Have a 87 K5 Blazer with a 10 bolt rearend and the axle bearing went out and put grooves on the axle where it rides on the bearing. My question is: Is the axle trash now with grooves that are on it due to the bearing tearing apart? Can the axle be turned? Not much on rearends and I see there are some great guys in here giving out very good information.THANKS!!
