Missing grease zerk, should I be worried?
So I finally got around to greasing the chasis on my own today. Found 5 out of 6 zerks no problem. Where's #6? Come to find out the propeller sliding shaft yoke zerk on the rear was gone. Just an empty threaded hole. Instinctively, I replaced it and pumped a couple squirts of grease (Amsoil Syn Racing). But now I'm wondering if I should be worried or not... 40,000 miles, and I have no clue how long this thing has been missing.
I also changed the front and rear differential oil. Was very easy thanks to this forum. Spark plugs and transfer case are next.
Thanks for any input or opinions,
