You need a 38mm or a 1 1/2" 12pt crows foot in order to properly torque the inner tie rod to 100#.
Also, if any of the ball joints, on the back side of the hub, don't want to come out by using the Torx - 40 bit and the 21" wrench, you can strip the rubber bushing off the joint itself and get a pair of heavy duty vice grips on it to keep from moving. You'd need an air gun to get the bolt off from there.
Next, I found that an air gun is "almost" essential for any one doing this DIY in a northern state.
Use Kroil Oil and soak the joints over night, you'll be glad you did.
It would be extremely helpful to have ratchet wrenches, no question.
Just a couple of tips
I bought the 11 piece set from FCP Euro and Lemforder Tie Rods and did it all in one, fell swoop. I had 130k on my car though.
