Replaced alternator due to over charging issue. Truck was running fine and in the next moment it sounded like the motor was knocking. Luckily I keep an eye on my gages so no major damage was done. However it was really inconvenient because I had to replace the alternator late at night. I can only figure the voltage regulator went out and caused the issue. After I replaced the alternator there haven't been any other issues like this.
