I don't think I've seen a write up for the steering intermediate shaft TSB yet. Rather than replacement, the latest TSB (as of 9/2008) says to use the grease kit and labor is estimated at 1.1 hours. I replaced my steering intermediate shaft 2/2008 and the problem is coming back. They cut me a small break on the replacement so I think I paid closer to $400-450 when I replaced it.
I talked to the dealer the other day to let them know that the problem is coming back and to my surprise, they offered to cover it for me. I forget where but someone estimated the prices for the grease kit to be $22 and the labor to be $200 if you're not doing it yourself.
I'm glad this isn't a safety issue, but it sure is annoying. I just hope this latest fix lasts until I get rid of the car
