my front main oil seal is leaking how much of a pita is it to replace and how is it done. Any how to links?

 

Really not too hard to do definately make sure its not the opti seal or the water pump seal leaking down onto the crank seal making it look like crank seal is leaking, water pump and opti seal leak more often than crank. I have done mine 2 times, remove the 3 bolts that hold on the balancer, remover balancer then hub needs to be pulled off and pressed on. Iam not good at typing out directions on how to do things so suggest "search" to find proper way to pull off hub and install hub so you dont damage crank threads or break bolt off in crank. The hub does not pull off and press on like older small block chevys.
