So I have a 1995 ford f150 I got new coil springs put I. The front end and then took it for a ride after I got it back and when I start to go about 30mph and up I get a pretty loud shaky kinda humming sound. The truck gets some viberations and an annoying hum. It never did it before. Also I feel sometimes that when I put it in gear of any sort it'll sometime like jerk. Also if I'm going and giving it gas is the only time it's got that hum and stuff. Also if I'm giving it gas and let off you'll hear and feel like a slight clunk. Sometimes louder and harder then others. What could be going wrong ??
