Grease is one thing, we're guessing person who did the original work, did not remove the rust around the axle. Pitted and rusted there. My local mechanic fixed and cleaned up the mess left behind, 6 cans of degreaser, I owe him a case of the stuff. Brake Shoes went into the degreaser < 3 k on them couldn't see replacing. About 3 hours of labor. Local shop wanted almost $500 to fix, my guy < $200.00.
