If I pull off the harmonic balancer, will I be able to immediately access the seal to replace it?

Yep, the seal is pressed into the front cover, but you will need to remove the timing belt. Check out the images (below). Please let us know if you need anything else to get the problem fixed.

Is it the same procedure for the 4x4 model? Thank you so much for your help.

Glad I didn't do what you suggested. That procedure must be for a different vehicle. Your answer to my question was wrong. I removed the harmonic balancer, timing cover, timing belt and sprocket, and then had access to the oil seal. I pried it out with a flat screwdriver and then pressed the new one using the crank pulley bolt, the sprocket washers, and a sleeve I made from a section of vacuum tube. If I had followed your advice, I'd still be stuck! Thanks for trying though.
