heard a loud pop from the rear, what can it be

i was driving on the freeway to work and i heard a LOUDASS POP sound from the rear of the car. it sounded like my tires popped but when I got to work the tires look fine.

I was just in 5th going straight and wasnt shifting or turning or anything
what do u guys think it might be

by the way im using coilovers but I dont know if it could be that. can coilovers blow like that and make a pop?

i didnt see anything fall off my car in the rear view either

I doubt the subframe would make that popping noise if you were going in a straight line at a constant speed. I have only gotten it turning or going up a big curb. You probably kicked up a rock or a piece of debris.

just throwing this out there...ck your rear lugs. sounds crazy but its happened to me before. i put some different rim/tire combo back there that put to much stress on them and caused the lug studs to break. first one it popped i didnt know what it was, second time it scared me but still didnt know what it was, third time it happened, my left rear side just dropped and rim was being held on by one stud.

Like everyone else said could of just been a rock that flew up into your wheel well or hit the body. Might wanna check the strut shafts on your coilovers just to make sure they didnt snap.

My subframe will clunk going straight, if you dont have sub collars there is about 1" of play, and hitting a crease in the road with blown bushings will cause this clunk.

I put on spacers and my passenger end clunks like a bitch sometimes, everything is tight.
