04 chevy fullsize crew longbox . very loud annoying rattle at bottom of column,anyone else have or hear of and how to fix

 

Probably the intermediate shaft that eventually rattles on all of them. The cheapest way is to pull it out and regrease it yourself. Supposedly GM has a newer version that won't rattle, but I haven't heard anyone confirm that. I just pull mine out and grease it periodically. It takes about 30- 45 minutes depending on how handy you are. It will be quiet for 15,000 miles or so depending on your driving conditions.

 

Intermediate steering shaft is the problem. I had the same issue with my 06, finally took it in and had the new shaft installed. The clunk is gone, 95% of the people who have had them replaced have had positive results. There was a bad rash of shafts that began to clunk after install but GM supposedly got that issue straightened out.

 

yeah,but i already replaced int. shaft 8months ago

 

Is it the same noise?

 

maybe this is the problem on our 07?
