hi. i hear a single clunk noise from the steering system when turning immediately from right to left and vice versa. Any ideas and is it dangerous?

this sounds like there must be some play in a steering joint or suspension joint

I'd suggest jacking the car up so the front wheels are off the ground and then have your assistant hold the steering wheel steady while you wiggle the road wheel from side to side and top to bottom

there should be no play in either direction. Any play in 1 direction will usually require a joint to be replaced, if there’s play in both directions then the wheel bearing may be at fault

also check for any play in the universal joints on the steering column

. If theres play only up and down its the strut top mount - to find this one you have to shake the suspension strut it self up and down with the wheel off the ground - so you may need to remove the wheel to check this one.

To feel if there's a worn strut top bearing then lightly hold the spring by hand and have your assistant move the steering from left to right with the wheel on the ground - a worn bearing will feel 'notchy' through the spring. The wheel needs to be on the ground for the test to load up the bearing

play in suspension joint or a wheel
bearing needs to be sorted out straight away as this can be dangerous, but a column joint or strut bearing is not quite so urgent
