FRONT WHEEL DRIVE -
Front wheel drive axles consist of [CV] constant velocity
joints, which are filled with grease and contained in rubber
enclosures called boots. When test driving a vehicle with front
wheel drive, first turn the wheel all the way to the right and
slowly accelerate. To test the other side, repeat this procedure.
If the axles are bad you will hear a bad clicking noise from the
axle. Visual checks on axle boots are also recommended. If
the boots are broken, usually there will be grease thrown around
the inside of the front tire area and on the tire itself. If you
see grease inside of the tire area, these axles more than likely
need to be replaced.
