Hi people!can anyone help?well basically drove my 2005 cdti veccy Sri 150 on a 100 mile alround trip today and something really out the blue happened!as I went to park up for the night whe turning the wheel the steering rack sounds like there's sand or stones in there instead of power steering fluid.also I know the brake discs are badly corroded but would this make a grinding noise when turn the steering wheel?the noise comes through on left and right turning but worse when I turn the wheel to the left.the noise has never ever been there at all.I just want to apologise to the long essay but it's doing my head in!!!once again thank you in advance!daz
