2004 Silverado Front End Clunking

Probable the intermediate shaft, a known defect. There is a newly designed
shaft that has so far eliminated my clunking.

My 2000 Silverado 4x4 Z71 Ext LT has had a few front end rattles

when the driver's door was slammed:

Had a loose drivers door window power regulator (FIXED)

Had loose self tapping bolts on the front Cross member skid plate
(FIXED)

I now have a mild 'bump' rattle after the 4 Z71 shocks were
replaced at 75K miles
with stiffer Monroe Reflex units. (Not Fixed yet)

Its most likely the ISS, its a known issue. Use a cord/rope/chain/whatever
to hold the steering wheel from turning and unbolt the shaft at each end
and remove it. Squirt some grease in the shaft and use a rubber stopper to
plug the end (you can get them in the hardware stores) and compress the
shaft to squeeze the grease into splines of the shaft.
I think this spring I'm going to drill and tap mine for a grease fitting.

So are you suggesting that GM's fix for this is to install a replacement
intermediate shaft that has a grease fitting?

GM's fix is to install the redesigned shaft.

I know that, but I'm asking what's different about the replacement?

It don't clunk?

No, they put in the same shaft hoping it will last until your warranty runs
out or you trade it for another truck.
If you don't and complain loudly enough you sometimes get an updated shaft
that doesn't clunk as soon as the original.

I had mine replaced out of warranty for free. Had to convince the service
writer, but they did do it, so far so good.
