Urgent pas help!!!!

  1. #1
    hi guys

    i need your priceless knowledge urgently!!!

    iv just replaced my pas pump as it packed up last week, know i fitted it correctly, bled it correctly and its works great,

    however when i turn the wheel to certain points and rock the wheel backwards and forwards, it makes a weird rubbing noise?

    also whats the black box behind the steering rack on the drivers side with piping coming out of it?

    Thanks
