Hey, I think I got that dokka dokka dokka! Luckily I haven't heard any CLINGK between shifts. Thanks for those sound effects!
Come to think of it, when I was originally working on the car years ago I wanted to grease the UJ but couldn't get my dang grease gun in there, so I left it. All other fluids and zerk fittings were done though. I should get under there this summer and take another look.
