#18 of 19 noise?? i am puzzled by justin26 Apr 30, 2009 (6:15 am)
i have a friend who bought a wrecked car and had it fixed. it was a front end crash. after it was fixed there is a constant grinding noise it sounds like and exhaust noise but its too constant to be that. i have another friend with the same model and circumstance AND the sme noise. its not a wheel bearing noise because they were replaced with new spindles. it is a constant noise when ever the car is over 10 mph. any help would be awesome thanks.

Replying to: tonlove1121 (Nov 25, 2008 7:23 pm) Did you ever find out what caused this in your car? I have an 03 GA 3.4l V6 - new plugs & wires, coil packs, new fuel pump, swapped MAF sensor & fuel pressure regulator (no change) car runs rough acts like too much fuel, cat turning red, putt putt sound...SES light on and was coding P0300 random multiple misfires. Not losing oil, not losing coolant, no overheating. It is going to the mechanic's but it would be nice to have more of an idea of what it could be! CrimsonGlory
