My '98 Sahara has a noisy exhaust leak that quiets down after a couple of minutes. This is a used Jeep that I bought about a year and a half ago. After my neighbor complained I investigated. The fasteners around the exhaust port for the #6 cylinder are missing. There should be a bolt and washer on the top together with a stud and nut on the bottom. The parts guy said "those studs are known to break" and, sure enough, he's right. I can probe The remains of the stud just below the level of its threaded hole.
Q1: Is there any hope of replacing the stud with the engine in the Jeep.
Q2: What happens to lazy people who simply replace the bolt and ignore the broken stud?
