I assume the noise sounds like "tok tok tok tok tok tok tok tok tok" when you are turning your steering wheel at very low speed. The tok noise is consistant and the faster you turn your steering wheel the closer the frequency between the "tok _tok". The noise becomes more when your car or one of your wheel is on an inclination. And if you drive the car, on the move, there's no noise. If that's the case, No, nothing to do with your steering assembly which includes your steering rack and pinion assembly, tie rod and ball joint, steering column. It is the strut mount bearing and coil spring rubbing each other. No safety concern unless there is a knocking sound when you brake. For those guys who lower their cars with a slightly worn bearing, the noise is even more prominent. Don't waste your money rectifying the fault. If you intend to, go and replace the strut mount, replace the shock absorber at the same time. Don't do a double job next time. Anyway shock absorbers lasts about 50000km and their damping forces drop drastically. For those cars above this mileage, it's about time anyway. The KYB dampers are not bad. Cheap too.
