Lexus is200 front wheel wobble at low speeds

[Codes]

Hi, i have a 2002 is200 that was making a few weird sounds from the left front now it made  a decent clunk noise and now i get wheel and steering wheel wobble at about 10 -15 mph, checked all parts that could be loose, could this be the wheel bearing ?

jack car up at front and in turn hold front wheels at 3 & 9 and 12 & 6 positions and see if you can rock.  Also, turn wheels and check for smoothness.  Check brakes not binding or partially seized.  Check discs not excessively lipped preventing proper contact with pads and that pads are good.  Check anti roll bar bushes allowing movement and other joints. I take it wheel bolts/nuts tightened opposingly in correct sequence to correct torque if wheel has been removed.

If you can't find anything amiss, suggest you then take to decent garage for analysis. One test they could do is to put your car on a rolling road and check when brakes comes on they do so uniformly and progressively.  I don't know if your model has  rack & pinion or other type of steering but just possible slack/wear here causing clunk. 

Interested to know what problem is found to be.
