So, my FJ60 has been my daily driver for three years now, with minor hiccups along the way as any 40 year old car would have. But today, I started hearing a very awful noise coming from underneath. Fairly certain its something in the transmission or the transfer case. I have provided a video above of the noise. The noise goes away when I have the clutch pedal pressed, noise is very bad in first gear, bad in second, goes away in 3rd gear (I live in the city wasn't able to take it into 4th) Noise is also prevalent (but not as bad) when it is just idling like in the video above. Sounds almost like a chain pinging noise , transfercase in 2Hi is the only thing I have tested.
