I have a 2000 Cadillac Deville DTS. Recently I took my car to my mechanic to repair a coolant leak and a power steering leak. On the power steering leak they found a line leaking which they r2 and the leaked stopped. After I noticed a hissing/humming noise coming from the power steering system. It only happens when there is no pressure applied to the steering wheel. The slightest pressure applied and the noise will go away. At times it seems intermittent and also sounds like the hissing turns into a gurlgling sound. It almost sound like its electrical but I know its not. I have taken it back several times to the mechanic with no luck. Right now its in the shop and he said its definately coming from the rack where the lines attach. I hope he doesnt try to make this like its a NEW issue because I did not have this noise until they changed that line. Any ideas/suggestions so they dont try and blame it on something else thats going to cost me more money?

HI there,

Thank you for the donation.

I would be flushing the oil and making sure that there's no air in the system, also I wold see if they can do a pressure test on the steering hydraulics there also may be a small piece of dirt or grit under a valve seat and a flush may dislodge it.
