Well I have had a power steering leak for a while now but I have had people mash the brakes and turn the wheel while I'm under the hood and I can't find it. Is there a common place these trucks start leaking ps fluid? Any ideas welcome! Thanks

 

Degrease it real good, let it dry, and crawl under there, you will find it. I'd be willing to bet your leak is on the drivers side front

 

the steering box seals are natorious for going out

 

Is it leaking PS fluid or engine oil? If it's oil the vac pump needs rebuilt and is pretty easy to do and cheap. You can get the kit from Cummins for under $30.

 

try some trace dye
