I have a 1996 4x4 4 door and its never been off road, there is a loud clicking sound every time I push down on the passenger side and nothing on the driver side? I dont know if you can hear it while driving because I have not been able to drive it for a while..

Listen to the video>>>>

id say to check your ball joints, the sway bar end link, upper and lower a arm bolts. also check for play in the hub

 

Jack up the truck and grab the wheel and check for excessive play. North, south would be ball joiints. East, west would be hub/bearing. Check your cv also, does it do it when making turns?
