crank seal leaking

[new jeep owner]

I did a search and couldn't find much info.

has any one replaced the crank seal ?
Is there any thing else I should look for/replace while I have the bottom pulley off?

I've done mine,not hard at all but you will need the special puller for Chrysler crank pulley's.Took me less then 20mins to change mine,$10 seal at the dealership.
