Muuuch better audio this time with different angles/help of a friend driving. Taken around 80 miles. One thing I forgot to mention was the engine performs fine; good power/acceleration. It just sounds like an old engine... and I'd like it to last longer than the 3-year warranty the company provided
Knocking/rattling noise clearly heard from this angle with engine idling. Again, heard best when standing on either side of the jeep. Loudest lying right under lower engine cover.
Camera being held out the passenger side window. There are 2 distinct abnormal sounds. The louder is a "hissing" noise heard only when accelerating. It sounds like a cicada insect when driving with the windows opened. The second is the baseline rattling/knocking heard when the engine is not accelerating (see other video to hear this better).
