Does anyone know where I might locate the hub nut tool needed when replacing the front wheel bearings? I've tried the method used by some, which is to tap them open with a screwdriver and hammer, but all that did was ding up the hub nut. An old post from planet isuzu suggested buying the part from NAPA (it's discontinued) or buying a similar tool for another vehicle and grinding it down to fit (i don't have access to that type of equipment). Any ideas where I can find this tool ??
