I dont know what year your mower is but i do believe that honda owes you a new set of spindles for your mower. This may just be that my dealer is able to pull this one but he gets everyone new spindles unless you are already using the new grease spindles with the grease nipple on top. I would talk to honda about this and talk to your dealer as well. Honda knows about the defects in their greaseless spindles and will usualy replace them for you.
good luck and any specific question just ask, i will see what i can do.
(I wonder why my dealer never responds to anything on this forum, i know he reads it?)
