It first started when I was cruisin around 50 I'd let off the gas and it sounds like u can hear somethin spining after awal it has started to do it at lower speeds to.if I am runin low rpms like goin up a hill and my tranny switched in gear it will revup some and go down untill I speed up. That was befor I went to the track. After I went to the track a few days later I go to take off fast and hear somethin from my front left pop when it raises it up but not when it goes back down idk help please.
94 dak auto 5.2 and almost 219000 hope it isn't dyin anytime soon

 

Ok so I realized today if I'm goin and its makin that noise if I put it in neutral it goes away but put it back in drive and u can hear it untill I accelerate.... Someone said when I tak e off and it pops it might be my strut
