Steering problem - is there any return valve in steering wires ?
From the couple of weeks I've got problem with steering. The steering wheel shudders slightly, while parking etc. (small speed). Additionally vibrations move on body. Few days ago I changed steering rack to another, which has been regenerated. This helped, but only a little. Next I replaced reservoir, pump (all new from service) and once again liquid. I buy Tutela GI/E (red) because the new pump was orginally flooded with it. This help and the problem gone. Suddenly after two days, when steering worked perfect, steering started to go a little harder and strange noise came back.Interestingly, when the car is cold after night (around 0 celsius degrees outdoor) steeng works fine, but after driving for arounf 500m, the problem came back again.
Someone told me that in the high preasure wire (between pump and steering rack) is a return valve. Probably inside the wire, closer to the steering rack. Is it true?
Thanks for help.
