Clunk noise from front left suspension

indicates that the suspension arm bushes are broken away from the metal bushing at the ends
have a professional suspension shop check for torn insulators in the suspension arm

if it has strut suspension, check for a failed bearing in the guard at the top of the strut
check for loose /worn rubber mounts on the stabilizer bar to chassis

Get it to a reputable suspension shop to have it checked out,if it was said a part on the steering then you don't want to risk losing steering when the worn parts break.Speculating it could be tie rods,sway bar links,ball joints,bushings etc etc everything that moves when you hit the bumps.

It's the anti-sway bar endlinks. My '06 g35x has the same symptoms - clunking at low speeds, varying from which side of the car the noise comes from as to which side of the car is hitting bumps in the road surface. EASY to replace yourself with the front end on jack stand, and you don't even need to remove the underbody plastic panel, so it's quicker than an oil change. To verify this is the problem before you order the parts (which are about $100 for the x, as it's a different part altogether than the endlinks on the RWD sedans or coupes, so be careful when ordering), just remove the current endlinks and take a test drive - don't worry about removing the whole sway bar, just the links at the ends of the bar). If this is the case, you will not hear the clunking any more. I do not recommend driving like this for any distance, as the car will become tail happy and your sway bar ends could point towards the ground while left unsupported and become damaged.

A clunking sound in the front is very often the CV joints. This should be more obvious in a slow tight turn. If it is not the CV and is more noticeable on rough roads it could be any one if the suspension joints.

It's hard to tell, from your description, as to the extent of the clunking.
If it seems to only and constantly occur whenever in forward motion, bumps or not, then I would first check your rear differential, (if 4x4 then your front differential as well).
Check fluid level(s) and if okay, remove cover and check for worn gears and any metal shavings on the magnet on bottom of housing.

Worn gears can toss your vehicle around, any make stomach turning clunks and other awful noises. I've recently replaced a front differential on a 1994 Dakota. It would make same clunks as you describe and a few times would make my back end seem to 'hop' while driving highway speeds. I would check this quickly.

If it only seems to happen over bumps, then your guess on engine mounts or bushings is probably the best guess.

You might want to check the ball joint. None of them have grease zerks and can dry out. They will cause a noise when turning or hitting a bump, if really bad. Hope this helps.

have a shop check the rubber control arm bushings in the front end,they are the usual source of this clunk

its probably your sway bar end links, I had the same problem, I replaced both sides and the bushings and no more clunk noise

Check the front struts ( shock absorber ) If original or very old, they are doing no good. Also check the front TORSION BAR rubber bushings. In low temps will groan and creak, on up and down motions.
