It really didnt look bad but since I was already there I changed it out. Still have another new one in the box.

 

Hello I want to replace the IWE actuator on my 2005 Ford F150. I am loosing vacuum on the driver side actuator and I have purchaced a new part. Does anyone have any PDF files with instructions on how to replace??? Is this an involved process??

If you can change brake pads you can do this yourself. The above link is actually better than the Ford PDF stuff, but I can PM (PDF) it if you want...

 

thank you so much I am going to try to replace it myself!! great help!!
