Steering Gear - Intermediate Shaft

Greetings,

I have a 2004 Chevy 2500HD crewcab with the diesel and Allison tranny and recently bagan to notice some clicking in the steering linkage when making slow, sharp turns (like in navigating in and around a parking lot). I took the truck to my local dealer and after looking at it they told me it was the

intermediate shaft in the steering. They are ordering the part (about 1-2 weeks) and they are covering the repair under warranty so the only thing I'm out is a day in the shop - no biggie.

My questions are - is this a common problem, and will the replacement part truly fix the issue without me having to have it done all over again in another 15,000 miles?

Thanks for any insight.

Cheers - Jonathan

Very common problem, and it's been around ever since the new style trucks were built. I'm surprised that they are ordering a new shaft, maybe there is a different procedure on the 2004 trucks, but usually GM just wants us to re-grease the slip yoke section of the shaft. I'd be surprised if the new shaft fixes the problem permanently, unless they have actually decided to re-design the shaft properly instead of just wanting to re-grease it every year.

Are we talking about a shaft that runs from the steering column to the steering gear box or part of the linkage that physically pushes the fronts wheels from side to side? Please describe how to grease the slip-yoke - is there a zerk fitting or something that I can do myself when I change my oil and where it is exactly located. I hit all the zerks I can find on the steering components, etc. when I change the oil as part of the routine self-maintenance every 5000 miles, but maybe I'm missing one (or two).

Thanks for your time.

Cheers - Jonathan

It's the shaft that runs from your steering column to the box. It has an inner and outer section, inner section slides within the outer section. You pull the shaft out, and using a special kit that GM has, you force grease into the two sections of the shaft. You need a press to do this properly. I wouldn't worry too much about it if your are getting a new shaft.

They dealer lubed the steering shaft on my 2000 GMC Sierra SLE at around 20000 km. At about 40000 km or less it started acting up again. They replaced the intermediate steering shaft and it has been quiet ever since. 69000 kms on the clock now.

There is a TSB with a new design for the shaft. That's probably what they ordered.

maybe

Ian, Does this apply to the '99 new body style 1500's? My intermediate shaft doesn't appear to have a slip joint. It looks solid from the column to the u-joint with accordian-like crush areas at each end. H
