This thread helped me diagnose my own whine. - https://forum.ih8mud.com/60-series-wagons/196873-fj-62-whinning.html I was having the exact same problem. I originally found this thread many moons ago while trying to diagnose my own whine. When it was starting I was the only person who could hear it. To me it sounded faintly like a small two stroke bike riding next to me. I could not hear it from the passenger seat. It finally got so loud that I would have to turn the radio up to drown it out. In the end it sounded like a swarm of bees were under the car. This was KKT's Idler Shaft. So more than a year later.. Here is my own Idler Shaft – Looks familiar huh? I went to Mudraks for the t-case rebuild because I know better than to do this type of work on my own. While they were under the cruiser they cleaned the transmission pan Did a new gasket on the oil pan to hopefully fix my annoying oil leak. Mudraks Rocks! Gary is super cool. Looks great and I don't hear any whine! We switched motor oil to Redline Synthetic - also went synthetic in the transfer case and transmission. For a shake down drive we drove to Monterey and back for the weekend from SF! I think I will drive it to work to morrow just because.. 5/6/09 update - the oil leak has been fixed 100% by changing the oil pan gasket! ..
