most likely drop link rods worn common fault on zafira apparently
possibly hitting the front bumper
Worn Ball Joint
Worn front axle and/or front end component.
is it front wheel drive? if so the cv joint is bad
Constant velocity joint! Pending the make it's around 100$ for a new one
On a front wheel drive car probably a damaged constant velocity joint clattering
of coarse it can, if the valves are not opening at the right time you will get this problem for sure
Pull to the right.
I would check the suspension bushings, if one of them is worn it would cause a knocking noise.
its to the right of the steering wheel
Turning right loads the left front wheel of the vehicle, so if you hear the knock when you turn right the bad CV joint is on the left, and vice versa.
AnswerNoises have to be heard to correctly diagnoise. TAke it to a garage. But a good place to look for a noise when the driveline is under torque ( accel and turning) would be the CV axles.
