I had my rig in the shop this week because my power steering was making a straining noise. Mechanics flush the power steering clean out the reservoir and everything sounded fine for 60 miles and then when I got into my driveway clanking sound and by this morning all the fluid have leaked onto my driveway. I can't replicate that clanking sound. My ace fluid is fine. I'm planning on having rig towed back to the shop tomorrow but any thoughts I want the issue is could be helpful. Thx! Matt

 

Sounds like a line, or maybe a loose hose clamp on the low pressure line at the pump.

 

Definitely check these. Also the steering box feed and return o-rings may be worn or nonexistent if the mechanics messed with it.
