There is a common issue with the 1999-2005 Grand Am with the ABS/Traction Control system. The problem ranges from being intermittant, usually during slow-speed turning manouvers, to constant, every time you drive the car.

The problem usually is tied to the wheel speed sensors, or the electrical connections to these sensors. The front seem more problem-prone than the rear. As 'first-aid', the preliminary step usually involves removing the wheels and inspecting the wiring and connector If everything looks intact continue on.

Disconnect the connector, clean the contacts, give it a dab of dielectric grease, and reassemble. If the problem persists, it is best to have the DTCs (Diagnostic Trouble Codes) read to determine the malfunctioning component. Once that is determined, replace the malfunctioning unit. The wheel speed sensor is part of the hub assembly and can not be purchased seperatly.

Defective fan clutch, if it has one. With a cold engine only, try spinning the fan blade by hand. If it does not turn freely, the fan clutch is defective. Warning: When the engine is hot, the fan can turn on by itself with the car not running and keys are NOT in the ignition.

Rear end on f-350 makes roaring noise. I checked oil level and it was ok. The oil seems to be very thin. Could wrong oil cause rear end noise?


Differential roaring noise is usually caused by a bearing that is worn or has pitting in the bearing race (half of bearing without rollers). A whining noise would be caused by worn ring and pinion gears. the roaring could be from the carrier bearings (two bearings holding the differential case to the axle housing) or fron the pinion bearings. The fluid is typically heavier but will seem thin when hot. The fluid isn't the causing of the noise but if the wrong fluid is in the differntial it could have caused the bearing to go bad which then causes the noise. good luck.

FRONT END


Drive the car in a parking lot and make left and right hand turns.
If the noise goes away on either turn then the problem is a front hub bearing.
If the noise is still there, it could be possible front differential bearings.

That is an intake backfire, meaning you have the valve timing wrong. Not quite sure right now on what it should be but check timing belt position and valve timing gear positions.
