I recently bought a 1985 fj-60 with about 1/4 million miles on it. It is in great shape, but has one major problem that I haven't been able to figure out. Whenever I am really making the truck work, like to scramble up a steep hill or to keep from being smashed by a semi a loud metallic grinding noise comes from somewhere underneath. It sounds like rrrrrrr-rrrrrr-rrrrr and gets higher pitched as the rpm's increase. It only happens when the truck is in first gear and when it is really working hard. I haven't been able to isolate the noise since I am pretty new to the landcruiser game and since it only happens in situations where the last thing I have time to think about is where the noise is coming from and no mechanic I have taken it to has had the slightest clue. So, if any other 60 series owners have had this problem any advice would be greatly appreciated. Thanks a lot.
