THE thread is a std Left hand to undo But you will need a 3/4 drive100 lbs air rattle gun to both undo and redo up the bolt on front pully.. BUT there is another way and that is as you say a big breaker bar and a good socket, but you will have to take off the starter motor and put a good fitting bar into the starter ring teeth and turn it to the top and dont let it slip out of the teeth and once locked into place gently put pressure on and undo the bolt..
But its unusual for the seal to leak on its own as its mostly due to either the front pully has worn a grove in it or the crankshaft bearing is also worn, so check the front pully for wear first. Ron

First remove right front tire and support vehicle with a jack stand. Remove splash guard lower portion near the harmonic balancer. Remove all drive belts. First remove the A/C alternator belt. Loosen the 14mm bolt at the front of the belt tenioner and then loosen the tensioner bolt (it is the one that stands out, you use a socket on it.). The power steering adjuster bolt with be gained from the bottom. It has a 12mm bolt head on it. You will break the jamb bolt loose first and then loosen the adjusting bolt. Pull down on the belt the help move it after you've loosened it some.Then remove harmonic balancer bolt (19mm).If the harmonic balancer will not slide off the crankshaft then use a two finger gear puller. Place the harmonic balancer bolt back in the crankshaft but do not tighten it. Leave it about a half inch from being all the way in. Next place the puller onto the harmonic balancer (one finger on each side securely press into the belt groove. The center puller bolt will rest against the harmonic balancer bolt head. Tighten the puller bolt and make sure the harmonice balancer bolt does not turn. The balancer should come off at this point.
