Sorry if I'm goin' blind, comes with old age. Thought I saw a TSB here dealing with 'rattle in steering at low speeds'. Is it gone? Never here? :confused: I have that rattle and would like the number before going to the dealer with it. Thanks.

Here is the one posted.

But, due to the lack of parts, they have changed it back to just lubing the shaft.

Thanks much, Sid. Guess I waited too long.

Had shaft lubed at about 15000 miles.
Had shaft replaced at about 25000 miles.
Dealer very cooperative with this warranty work. Did have to wait for the shaft a few weeks. It was on backorder.
03 now has 31000 miles on it and no more "clunking".

Thanks zahn.

Got an appointment to get it REPLACED Tuesday. WOW, QUICK, just called yesterday. Service rep. said they have them in stock and have done about 60 already.
