If it has any then replace because this is where the vacuum leak is. Here is the part # from JD AM133406. Cost is $74.20 If you go to the JD website you can View all the technical manuals online for this mower. You can also order the part and they will ship it to your local dealer. If you need any further assistance let me know and I'll try to help.
Thanks for the help Johnagain!

Do you remember if it was the left or right actuator that was causing your forward steering issues? I've had that area pulled apart when I replaced the steering switches last year and remember that there were two of them under the seating area. I'm just assuming that one is forward and one is reverse so any additional insight into what I may be looking for is tremendously helpful.

Thanks again for the help as I hope to try this today and see if I can find a crack in the actuators.
