2002 tune up
I have a 2002 f150 with the 5.4 triton. It now has over 100k miles on it. I have just got done changing all fluids, trans, transfer, oil, antifreeze, etc. It is running ok, but has a slightly rough idle. I want to tune it up, but have heard the spark plug horror stories. I love the truck, and want to keep it running good. What should I do to the motor to keep it running good? Also, do the front 4x4 hubs need repacked like the old style did? I have done no mods to this truck other than cutting the muffler off, and replacing it with a test pipe, that makes this truck sound good, but not too loud. Thanks for any information.

Re: 2002 tune up
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.
