Front-end clunk only in 2WD?

[ajevenson]

I have been trying to diagnose this one for a while. When in 2WD every bump I hit between 15-50km/h (10-30mi/h) results in a louds clunking almost like the front shock is bottoming out on the frame. As soon as I throw it in 4WD, no more noise! I can drive over my buddies S-15 in 4WD and it doesn't make a peep. In 2WD if I drive over a penny it clunk's at me. Any ideas?

the front end clunking noise is usually the radius arm bushings.... your 2wd / 4wd difference makes me thing otherwise though...
