Suggested Repair

Replace the alternator by disconnecting the battery, removing the serpentine belt, splash shields, front exhaust and converter, right drive axle, and related heat and cooling shields, then unbolting the generator. Install the replacement without binding it, torque the mounting and battery connections to the specified values, reassemble, and check transaxle fluid level.
