I chose not to replace the front main while the engine was out because I couldn't tell that it was leaking (due to all the other leaks), and because I knew it wouldn't be hard to change later. So after finding that it WAS leaking, I changed it. I broke the fan clutch bolts, removed the belt, removed the bolts and set the fan on top of the WP pulley (just high enough to clear the balancer), removed the pulley bolts, the balancer bolt's washer, and then used a puller to remove the balancer from the crankshaft. The original seal has a lip that can be bent out & then pulled to extract the seal from the timing cover bore. I put a thin ring of Hylomar on the new front main seal, and then drove it in with a 1-3/4" socket. After reinstalling everything, I hosed the engine off a few times, and then held it at high rev for a few minutes to check for leaks. It's dry, but I'll keep checking it each time I rinse it again over the next few months.
