To replace the front lip seal, you need to first remove the accessory drive belt(s). Then remove the crank pulley (3 bolts IIRC - if equiped) and the harmonic balancer retaining bolt/washer.

Next, install a puller to remove the harmonic balancer. A low profile puller may be necessary. I made one out of plate steel with 3 holes to match those in the balancer (used for the pulley) and a larger hole in the center with a nut welded to it. Thread a bolt through the welded on nut and walk the balancer off.

You will then need to pry the old lip seal out of the timing cover, and press in a new seal. Pressing in the new seal can be a challenge with the timing cover still on the front of the motor...
