Wheel bearings generaly don't make a clunking noise - more of a higher pitched squeaking or shrilling noise.
Don't mean that they are fine - they could be going bad. I'd look into the suspension hard points (bushings) for the anti-roll bar, spring/strut mounts, tie rod ends, etc. Over time, these bushings will soften and wear down, allowing much more suspension movement and looseness - usually ending up with clunking or thumping noises.
Bushing prices vary quite a bit - need a press to push in new bushing or replace the worn unit. Wheel bearings are not expensive, not really hard to put in either, but you would have to watch the bearing preload - not too much, not too little.
Prices in USD will run from $50 to $200 for bushings and around $40-$50 for wheel bearings.
Good Luck.
