When you turn the wheel the weight of the vehicle shifts and the frame bends slightly and the sound you hear is additional weight being applied to the bushings in those areas and the frame twisting slightly.
Steering wheel noises can be caused by low power steering fluid. A loose or worn belt or suspension problems can also cause a steering wheel to make noises when turned.
It's part of the steering column and if yours is making klunking noises it has to be repaired at the dealer.
check power steering fluid level. Also check belt.
the question is a little vague. most of the time the noises when turning going slow come from tires hitting a body part at extreme turn angles. also power steering pumps make noises when they are low on fluid, the steering wheel is being held past where it needs to be; a common thing you hear alot in parking lots. most of the time if you just relax the steering a little things sound better. hope this is some help.
Depending on the noise, starting noises are usually- the starter, belts, belt tensioner or bearings on accessories like alternator/power steering.
Grinding noises, wandering steering, strange tire wear.
