You do not repack the front wheelbearings,they are sealed units.They are known for eating coils when a missfire code comes.Put in Autolite or Motorcraft spark plugs and do not put in Bosch plugs.Bosch plugs do not last and are a piece of junk.Also change the fuel filter,it is a part of a tune up and is the most neglected part to change due to being under the vehicle.A plugged up fuel filter will put a strain on the fuel pump and kill it.
