There is a panel inside the wheel well that you can take off that gives you perfect access to the harmonic balancer. A special tool is required. i had my dad make one because he has access to whatever he needs at the factory. but you can get them at the dealer. i have no clue how much they cost. I can't see any way of doing it without the special tool. after you get the tool its pretty simple to get off. it takes alot of force to break the bolt loose though. i used the handle off my jack as a cheater bar. hope this helps...

To remove the harmonic balancer on my 1992 Pathfinder, I needed to loosen the alternator and power steering belts, remove the cooling fan (4 10 mm nuts), remove the radiator (2 10 mm bolts hold it to the frame, remove top and bottom hose [The drain **** is covered by what appears to be a coolant line], as well as the overflow tube to the reservoir. With a 3/4" impact gun and a 27 mm socket, remove the bolt that retains the alt, ps shieves and the harmonic balancer to the crankshaft. With a large 3 jaw puller, remove the harmonic balancer with the pully sheives as an assembly. I do not recommend attempting the removal without the puller.
To put it back on, you will need a large torque wrench for the crankbolt and a small torque wrench for with a crowsfoot for the fan nuts.

I have a '94 Tempo, it had a "ticking" sound. It was the "harmonic balancer" (crankshaft pulley) a local mechanic changed it for $60, the part cost me $120 (I work for a Ford dealership) $180 without employee discount. you can get one for much less at a junkyard if you can find one. Good luck, Sean
SOURCE: Remove the harmonic balancer without a puller?
You can try simply wiggling the balancer and see if you get lucky. A few taps with a rubber mallet may convince it to come free. Worst case get the kit. You should not need to remove the radiator. Do make sure that you have the engine blocked so you don't lose your timing mark placement.

Remove the hood, drain and remove the radiator, remove the belts, loosen the bolt into the balancer, replace part way, hook up a harmonic balance puller, tighten until balancer come free, remove puller, remove HB bolt, remove balancer.
Check seals before replacing, if damaged, replace, check keyway, replace woodruff key if needed.
Install is the reverse.
