On Michelle's 2003 LB7 she has been in to the dealer 5 times for a "steering shaft replacement however I believe a few of the times it was just "lubed" and not replaced. You can see from link what was done before.

The truck turned over to 80K today and when you turn the steering wheel either way you feel a "rattle"

What is it most likely?

I crawled underneath after I put the front end in the air and "looked" around however I did not see or feel anything that looked like it was loose or felt incorrect.

Any ideas?

Anything in the steering column that could be loose?

Truck has never been in an accident other than with a deer I got a few years ago on the way back from Bonneville several years ago :D

Is there an updated steering shaft that may need to be replaced?


Thanks in advance.


John & Michelle.

The intermediate shaft is a known bug in the Silverados. IIRC, there is a newer P/N now.

Mike L. was doing something with an improved aftermarket unit a couple years ago, I saw it at his shop. I don't know what became of it though.
