Hi,
My 06 with about 175k had a steering shaft that rattled like the whole dash was coming out. The bearing assembly (white plastic thingy) at the bottom of the column (inside the cabin) was a little loose. Pushed it up into the column, put a hose clamp around it and tightened the 'snot' out of it. Nice and quiet! It's been about 10k miles since I did that and it needs to be tightened again; the clamp has slipped a bit. Sounds too easy, but everything still works wonderful!! There are several threads on here about doing that fix.
Good luck.
