PMcClure Posted March 17, 2020 Report Posted March 17, 2020 If you are following my avionics upgrade, you know all about my new torque rod. However, after removing the old one, we found significant corrosion at the rear universal joint. See pictures below. The pins in the universal joint were very corroded and the joint was VERY difficult to move. I doubt failure was imminent but it was headed that way. I couldn't find any other corrosion or evidence of water around this area. Perhaps something you may want to look on your bird. Mine is only 18 years old. 1
