Well i just noticed this noise recently in the general area underneath drivers side front. when i reach about 15-20 miles per hour i get clunking noise and goes away after 20 mph. i was told u-joint so i replaced it only made it little bette i am trying to think what else it could be

Can anyone help please

 

More description. Does the clunk coinside with acceleration? Bumps, turning, ect.

On your lift did you replace the trackbar and is it tight? Are the bushings good in the Control arms? Are the arms stock or aftermarket? Are the hub bearing good? have you checked the motor mounts. Do you have extended sway bar link, stock can hit the spring when lifted/
