I'm currently having the same problem and ended up cross threading the fitting into the accumulator. The hardline bent a little when I removed it from the old unit. I disconnected the half-shaft (m10 triple square bolts x 6). This helps immensely providing more room to work! As for aligning the fitting try loosening the other end of the line that goes into the control valve. It provides a little extra play which might allow the top fitting to align better.
