Inspect the condition of the alternator drive belt. If the alternator drive belt is worn or damaged, check that the drive belt for the alternator and the pulley are correctly aligned. If the alignment is correct, replace the drive belt. Refer to Disassembly and Assembly, "Alternator Belt - Remove and Install".
Inspect the alternator mounting bracket for cracks and wear. Repair the mounting bracket or replace the mounting bracket. Ensure that the alternator drive belt and the alternator drive pulley are in alignment.
Remove the nut for the alternator drive pulley and then inspect the nut and the drive shaft. If no damage is found, install the nut and tighten the nut to the correct torque. Refer to Disassembly and Assembly, "Alternator - Install" for the correct torque.
