Has anyone replaced one of these, any thing I should look out for or be aware of

 

You should lock your steering wheel with the GM tool or a screwdriver can work in a pinch. The R&R of the intermediate shaft is not difficult but the end inside the engine compartment might be very stubborn (rust/dirt). Remove the driver side inner fender (plastic piece) for better access to everything. You can see and reach most of it from there.
YOU CAN NOT MOVE THE STEERING WHEEL FROM IT's STRAIGHT FORWARD POSITION. Many bad issues can happen if it strays from that position.

 

Second what tainter said. I've done this twice on two different H3's and you've got to have patience of a saint. Be very flexible and have dexterity to boot.
Just be methodical and did I mention patient.

 

Oh the rust issue if you have it will slow you down pb blast is your friend.

 

I got to mine from underneath. Pain but doable

 

Need to do mine as well, 2006 H3. Any video's on it?
