Left front "popping" when turning right under more than light acceleration
anyone experience this and/or know what it is? Spent a day at dealership trying to figure it out...several techs involved....
did the rear diff fluid change, circles, figure 8's 3 times...that wasn't it. Now it is also happening when taking off straight as well...under moderate to heavy acceleration...baffling. |

Check lug nuts on that specific wheel
I would also lift the front left corner , and try to move the wheel left/right , bottom in/top out , and see if it sings like when driving , I'm thinking about some link in that wheel is giving up Last edited by oldfriend; 04-20-2015 at 08:13 PM. |

I notice this problem when backing out of my driveway. Never heard it any other time though. Curious to what it might be.

I had experienced that noise also when backing out my driveway, but now after 2K miles it went away.

I am experiencing this also but it seems to be coming from the rear. I had mine at the dealership and after checking everything, they wrote it off to drive-train slack. I don't believe this since I have driven manual transmission cars most of my life. I guess I will wait for it to get worse so that they can figure it out.

Just got back from my tuner...right away...as soon as he felt it...he knew what it was---- the catalytic converter. He says they just don't last at this power level. Going to have them gutted Thursday.

What power level? Did the tuner give any reason why the cats would make a popping noise? Curious. Thanks!

This is a normal issue.
The brakes seem to lock up after sitting for a while. It's most noticeable after you wash the car or do some "spirited" driving and then let the car sit. The popping noise is the brake pads un-sticking themselves from the rotors.
