Damn poping noise
 

There is a poping noise in the front left of the car mostly during exceliration.

This is not my car, car i am interested in buying so what could have caused this?is it serious?

What kind of car are we talking about?

86 944 about 99k on it

its periodic but its pretty loud. cant tell whst it is, doesn't seem like its coming from the engine

I'd start by looking for a sticking caliper. A clue would be one wheel much hotter that the other... don't touch, just get your hand in the area. If it's warmer than the other side, the caliper may not be retracting.

Sometimes, loose or dying bushings can also make noise, take a look at the swaybar bushings.

Mostly, I'd look at the brakes and then I'd think about the wheel bearings...

Its not the brakes, we checked those and they were just replaced. Might be the wheel bearing but i'm thinking probably bushings if anything.

You can also check a sticky caliper by eyeballing the brake pads. The inboard pad will be thinner than the outboard when it's dragging. If this is the case your in luck! These calipers can be easily rebuilt with a $8 kit and an air compressor!

Check the sway bar bushings for end play, also jack up and check the control arm bushings, ball joint movement and bearing free play. It has to be in there somewhere. I agree with Shaun it could be a noise from the back sounding like it's up front.
