Not to brag, but I'm something of an expert by now.
Things to buy, 2 quarts of PS fluid, at least 1x M6x1x20mm bolt, replacement lines WITH seals
0 Park the truck with at least 6 feet of clearance on the driver side and 2 on the passenger side, put the steering wheel in a neutral position, then loop the seat belt through the wheel and click in place, disconnect battery, pull the battery (2x 10mm bolts and a 10mm nut for support bar, 1x 13mm nut for hold down) and battery tray (like 6x 13mm bolts, two on top into the fender, 2 low in front, and 1 or 2 low on the passenger side of the tray into the wheel well) Pull the air box and washer fluid reservior too (3x philips head screws, 2x 13mm nuts, 2x electrical connections, 2x hose connections) and set it somewhere where it won't leak. Pulling the fan and shroud would definitely be helpful at certain steps too.
1 Jack up the car as high as you can and pop off the drivers wheel.
2 Remove the aeroshield under the engine, 4x 13mm bolts
3 Pull back the flap at the top rear of the driver wheel well and with a 15mm socket remove the bolt from the steering shaft linkage
4 Remove the outer tie rod ends from the knuckles, usually a 21 or 22mm nut, then hammer on the knuckle where the tie rod goes through while lightly prying up on the tie rod, a few good taps and she should pop right out.
5 Remove the shield under the steering rack, should be 6x 15mm and 4x 21mm bolts underneath, and 2x 15mm bolts behind the rack.
5.5 Remove the 8mm bolt holding the lines into the rack and pry the lines out, drain any fluid left in the lines. Hint: Two 4-5" wobble extensions work pretty well for this, it gets you over the CV shaft.
6 Using a 13/16's spark plug socket (the type with a hex on the end) on the nut (forward end of the car) and a 21 or 22mm socket on the bolt, unbolt the two bolts holding the rack in place, pull the bolts and drop the rack. Tip here, drop the passenger side about 5 inches then the rack should come down vertically just fine. With the rack out do NOT touch the steering shaft, you do not want it to move at all if possible
7 Carefully support the rack so it's not resting on the pressure lines, use a flat blade screw driver to pop out the old cup seals, and install the new cup seals by tapping them in with a small hammer and a socket, my horror fright 3/8's socket was just a bit too wide, the 9mm would have been best probably. Reinstall rack in reverse of removal, congrats, you've got the hard part done, some locktite on the steering shaft bolt can't hurt.
Have a drink of water, gotta stay hydrated.
8. Remove the 3x 10mm bolts holding the line to the body, one underneath the harmonic ballancer, 2x on the frame rail. If the ones in the rail snap you can replace the J clips easily enough, but your brackets there are probably screwed up anyway.
9 Remove the return line from the cooler, it's just held on with a clamp. Remove the pressure line from the pump with a 17mm flare wrench, this might've been a 16mm and my set for some GD didn't have 16mm, can't remember. Make sure the o-ring comes out of the pump with the pressure line. If replacing the line from the cooler to the, this is held on with a hose clamp on the back of the pump, be careful with the reservoir, that plastic is brittle.
10 Using bolt cutters just cut off the old lines around where that rubber bushing is that caused them to rust out in the first place, the pull the rack ends up and out, then the pump ends out through the driver wheel well, this will sorta teach you how you need to fish them back in.
11 Fish the pressure line through so that the line crosses under the fan if you didn't remove it. Pry it up and over the strut tower, and leave the rack end resting on top of the brake lines coming out of the master cylinder.
12 Fish the return line in toward the front corner of the car under the frontmost crossmember of the frame, the pry it up over the strut tower.
13 Get the return line into the bracket on the pressure line, then zip tie them together, and feed them down toward the rack.
14 Using the new M6 bolt you picked up, start the threads into the rack and pull the tubes up close to the rack. Before you start touching get a long narrow flat head screw driver and come up from underneath the vehicle with it in your right hand and get it between the pressure line and the bolt, this will allow you to manipulate the angle of the hoses relative to the bracket, then continue to tighten with your left hand. You need to make sure that the hoses go in straight visually, having good lighting is imperative for this step.
14.5 Tightening the manifold to the rack you'll feel it tighten up a good bit, then go slack again, before repeating it, this is the pressure line seal and then the return line seal being pierced, then you'll tighten till it's nice and firm, remember don't go full gorilla on an M6. Note, if you get the "new design" hoses which use an o-ring on the pressure side, this won't be the case, only the return line will need to be pierced.
15 Making sure that the o-ring is on the pressure line, screw the new line into the pump. If you're replacing the line from the cooler to the pump, make sure to transfer over the bracket holding both lines to the frame crossmember, and reinstall that.
16 Reattach the lines at the cooler and fill the reservoir up with fluid.
17 Reattach the washer tank lines and electrical connectors, then bolt it back down, reinstall air cleaner assembly.
18 Reinstall the fan if you removed it, and the battery tray and battery.
19 check that the fluid level is good, top off if needed
20 Unbuckle the belt you put through the wheel, and turn the wheel from lock to lock a few times, check fluid level again and top off if necessary.
21 Start the car for a few seconds, shut it down, check fluid and top off as necessary.
22 Start the car again, and turn the wheel from lock to lock, pausing at full lock, keep this up till the whining goes away, checking for fluid level and leaks as you go.
23 Once satisfied with the sound and fluid level, make sure everything is buttoned up and cleaned, and go have another drink of water. Love me some water.
