Hello folks

This one has me beat, I have a 2005 Vigo, 2 w/d, 2.4 diesel, 5 speed

This just started yesterday, I hear a hissing sound on the front left hand side of the truck when I turn right at speeds over maybe 25k. Doesn't seem to happen unless I turn fairly hard right, and doesn't happen when stopped. Sounded like a hydraulic leak but there should be a pretty big mess if that was the case and there is no oil loss at all.


Crawled underneath, everything looks fine, all I could even think it sounded like was air blowing out of a tire or a high pressure hydraulic leak. Nether of thoughts are the case.

Any ideas anyone has would really be appreciated, I'm usually pretty good with cars and trucks but I don't even know where to start on this one. So even off the wall comments would be appreciated, might give me somewhere to start looking.

Thank You in advance
Wade

. Power steering unit? Check fluid level.

. Vacuum hose leak?

Thanks for the quick response.

Fluid levels have not moved at all. Vacuum leak I haven't thoguht of, will have to check into that in the morning.

Thanks Again
Wade

Just wanted to update this question I had asked in case someone has anything similar.

I found the problem a while back, turned out my A/C drain hose was plugged. The water level in the A/C unit wasn't high enough to start leaking on the floor but when I turned right at speeds the water would flow over to the fan side of the pan and the fan blades would hit the water making the sound. One good shot of compressed air up the drain hose and problem solved.
