I had this apart to replace the shaft seal at the top there on the picture in October. The car now makes a very apparent vibration when it is steered as if something wasn't quite tight enough in there, and it had just enough play to make some noise.
Now, my big question - the green arrow is pointing to the suspected part that may or may not be tight enough. When I reinstalled it back in the housing in October, I snugged it up to where it felt tight. I then put the lock washer over it, and went along with my business.
I pulled it back apart tonight, and it unscrewed fairly easily. I acutally used a tool to tighten it this time. Wow, new concept!!
Could this have been my problem?? How tight does it need to be?
