I'm having popping sound when driving at low speed like; driving on dip road in the parking lot I hear popping sound every time from both rear end. I can't figure out where's coming from. I also hear squeaking sound to. Shop can't figure out where's coming from so I feel like let Nissan look at it. In past we did rear subframe and control arm red lion bushing installed. Buddy took out everything like he put it on the ground, like he took out rotor,hub, brake components behind the hub. After that is started making the noise. I feel like my back end is loosen, because I can feel my back end hoping when hitting the bump at no matter how fast I'm going. Shop find strip toe bolts on rear camber arm, so they put whatever bolts they had, and they did not put new toe bolts, so I don't know if this have something to do with it.

 

I had a rear sway bar nut come loose and fall off once, it made popping noises.

Would only take a second to check.

 

Sway bar is not loose. I check everything in the rear and I can't make the noise when is off the ground. As soon tires is touching the ground, that's when it start making squeaking and popping noise, and also we can hear it while we jacking up the car. It make noise as soon we drive the car. Can it make noise if all the bolts is not propley tight enough?
