I had the same problem on my entry door. It "POP'd" no less then 3 times every time I opened or closed the door. I hated it!. I had the following person replace the entire mechanism when I was in Oregon this year. The door is so quiet now it's scary. He will send you the parts needed to replace the mechanism. He does want you to send back the mechanism that you remove from your coach, so all the parts that are bad are replaced. It has a stainless steel rod to replace the factory rod. It was a unbolt the old one, bolt in the new mechanism.

I watched him replace this item and if you are mechanically inclined, I believe you should be able to replace it.
