The front crankshaft seal is pressed on to the timing cover opening and its sealing lip bears against a machined surface on the harmonic balancer. On most engines of this type, the front seal replacement is simple.

Also, if the sealing surface of the harmonic balancer is worn, that might allow the new seal to leak and it should be replaced. On an engine where the timing belt must be removed to replace the front crankshaft seal, if there is any oil damage to the belt, it should be replaced.
This will save on labor costs later, even if it looks ok. On an engine that uses the timing belt to drive the water pump, usually, it is recommended that the water pump and timing belt be replaced together. On an engine run by a chain, if the procedure calls for the timing cover to be removed, that involves opening the cooling and oil systems.
