Well, I'm wondering if I may have found one of my problems in my project FJ40? When I traveled to and from my club meeting Wednesday night I noticed a bad knocking sound in the drive train. We were guessing it might be the transmission. I thought it might be the t-case input gear. So I drained the tranny & transfer case and I took off the rear cone. The t-case input gear had not moved. It was fine. Then I pulled the side cover off the t-case and found a broken tooth on my idler gear in my Orion. Do you suppose this could be causing my knock?
