One last question though...since the one I bought is not greasless what type of grease should I use and how much should I slop on the joints?
Thanks!

You don't grease it. It already has lubrication on the shaft

Nice write-up T! I like all the peektures.

What years/vehicles does this apply to (the shimmy/clunking that is)?

My appologeze Tobias. I'm in and out of being awake...still.

Any GMT-800...

Thanks for the write-up, I'm going to have to do this on the Avalanche... :/

I am surprised my Tahoe still has the original in it

After almost 4 years, I dont' even notice the clunk anymore.

Just got this done on the Avalanche this morning. No more clunks and vibration!

Like Jarrod said, you'll have to remove the gas pedal on the [I guess] 03+ trucks. You have to remove the two 10mm bolts holding the gas pedal assembly (disconnect the wiring harness by pulling the red tab out), then remove the three 10mm nuts that are holding the bracket the gas pedal was attached to.
