hi i got a ford focus 2002 1.6 iv add a new coil spring fitted on the right hand side but now when the cars on the floor under its own weight i put my foot on the wheel push and it make a nocking noise and the wheel wobbles but if i jack it up it dnt wobble any ideas????

sounds like the CV joint may be out... If you jack the car up, check each wheel at the joint, there should be a rubber sleeve covering it, is there any damage to it?
