I have been driving my 2004 Silverado for two years now and have had the
9,000 miles: Replaced leaking rack and pinion assembly. Fortunately, the
old rack was replaced with a superceded part, which might not leak.
15,000 miles: Replaced driver-side manual window regulator.
21,000 miles: Replaced driver-side air conditioner temperature actuator.
30,000 miles: Started dealing with Intermediate Steering Shaft clunk.
Somewhat relieved to find out that the front end isn't falling apart;
dismayed to hear that I may be obliged to pay and pay to have this
chronically-defective part serviced over and over again. If you're driving a
GM product and you haven't yet experienced the dreaded "Clunking Noise Under
Hood" which "Can Be Felt in the Steering Wheel", you probably will. The
problem affects all of these models as well as many others:
2002-2003 Cadillac Escalade, Escalade EXT
2003 Cadillac Escalade ESV
1999-2003 Chevrolet Silverado
2000-2003 Chevrolet Suburban, Tahoe
2002-2003 Chevrolet Avalanche
1999-2003 GMC Sierra
2000-2003 GMC Yukon, Yukon XL
2003 HUMMER H2
(Affected vehicles include both 2WD and 4WD)
* I copied and pasted the above information from the website below. The
updated information from the service bulletin that I obtained on February
13, 2006 takes the dates for ALL of the models listed above and extends it
through 2006. This indicates to me that GM has not produced a superceded
part which will permanently correct the Intermediate Steering Shaft problem.
I am going to check with the Chevrolet parts department today to see if a
new part is available.
Complete information is contained in service bulletin #1757365. The band aid
approach is have the dealer install a thicker, more heat-resistant lube into
the defective and/or damaged part. This procedure involves the use of the
Steering Column Intermediate Shaft Lubrication Kit, P/N 26098419, which is
currently on national backorder. As a temporary fix, my dealer installed
some of the earlier style lubricant and the problem seemed to go away.
However, last night, during a sharp low-speed left turn, the clunking noise
and vibration faintly returned.
Other than the discovery of the steering problem, my 30,000 mile "service"
was a complete success.
