Or try this one.

 

Interesting sound, possibly strut hat bearing needs greased?

With the popping sound that loud and precise you should be able to feel it with your hand by grabbing parts.

 

I would say top strut bearing is shot. not the cv joint for sure. U got coil overs?

 

Yep have bc coils.. I tryin feeling around when I turn. Control arms don't feel it.. Strut tops don't feel it.. Tie Rods dont feel it.. Don't think it's a wheel bearing... Lol lost with this !

 

Coils have 10-15 k roughly on them.. Not hard driving.. When it creeks you feel it through the whole underneath of the car. Not sure if I said this but when drivin low speeds 1st 2nd 3rd gear, if I'm driving and tap the brake it makes a single knock/pop.

 

That to me says it's a pivot point like the top hat, ball joint, or your cabs.

 

whose coils \? need information. if they are coil overs they are not correct, my guess install issues

 

I'll check them all on again tomorrow

 

Could this be where the knuckle that comes off the steering rack to the knuckle that comes from the steering wheel? Checked that too didn't see it jumping or skipping anything.

 

bc coilovers. u got a top strut mount problem or your lower bracket is loose as the lock nut has backed off. sorry.

 

Ball joint, thats another to check, but is put it up on jack.stands, and take a pry bar to every joint, ie lower control arm front and rear, tie rod ends, and look in and check.the ujoint on the stearing shaft, ball joint, strut tower top, and grab the cv axles and shake them, if nothing moves, get the grease gun out and hit every grease zerk you cab find, it could be just a joint ran out of grease

 

there are no zerks on a cobalt unless u have aftermarket parts like moog drop links. his problem is the coil overs..

 

Powell I installed them and I know I installed them correctly. You feel it's the top strut ball joint? Where it swivels and the dampening adjustment sits on? When I turn the wheel I had a buddy put his hand on top of both of them he said there's no feeling of the knocking on them. You can really hear it under the car. Kinds goes through the whole floorboard... I will check everything again tomorrow .. How can I check if the coil over joint up top is bad?

 

By the way thanks for all your guys help !

 

It don't make noise if I push the front end up and down also.. Not sure if it would Powell but jus saying that also

 

looks like mine was a different sound

 

It's drivin me insane.. It's gotten worse since... Can't find where it's coming from!

 

i kno how you feel bud

 

So I got wobble comjng from the passanger side when doing a pull 2d through 4th.. And under braking on the highway ... Possible wheel bearing going out? If I don't figure it out over the weekend I'm bringing it somewhere cause it's driving me insane!

 

Anyone think it could be the steering rack?

 

honestly after hearing the vid, it sounds like the coils are grinding around. i would take the out and put stock back in to see if the noise goes away. i noise like that would leave evidance of wheres its coming from.......

 

....? ha ive used 80ft lbs on my car for the last 3 years almost. every oil change i rotate my tires and use 80ft lbs. never ONCE had an issue. to give u an example, toyotas torque specs for the cars r 65ft lbs... and a camry weighs more than a cobalt... its gonna be suspension.

 

I had a friend put his hand on both strut tops while I turn the wheel and theres no knock or pop feeling coming from them.. Which makes me want to eliminate the coils. I'm not sure of I have the stock ones still I think I sold them but if not I'll change it out and see.
