So far the rack replacement is going well. I'm at step 12 in my procedure. Other procedures do not clearly tell you how to drop the sub-frame the 3-4 inches. The bolts will come right out when the sub-frame is only down 1/2" which means I will have to use my hydraulic jack to ease the sub-frame down. Pictures will follow.
Here's more to my procedure:
Remove Rack: Part 1
1. Disconnect negative battery cable. (already done if changing pump)
2. Set parking brake.
3. Raise vehicle, support on jack stands on pinch seam. (You will need to drop engine cradle, so supporting on sub frame is not an option this time.)
4. Remove wheels. If you need a picture of this, you should run from this job and call a pro)
5. Turn steering wheel (engine not running) to push fluid out drain lines. (Make sure the return line is pointing into your drain pan.)
6. Lock steering wheel in straight ahead position.
7. Push back rubber boot and remove pinch bolt at steering gear.
8. Unplug compressor cutout switch. (I believe this is for Magnasteer... I'm a poor man so I can't afford Magnasteer)
9. Detach power steering lines from rack. Place drain pan underneath to catch drips. (I'm doing this later. The nuts are frozen so I'll have to use some penetrating fluid.)
10. Detach outer tie-rod ends from steering knuckle.
11. Loosen front two subframe bolts. You will want to loosen them quite far. If you remove the bolt, then reinsert 4-5 turns, it should be stable, but low enough to allow the back of the cradle to drop 3".
12. Place jackstands underneath the frame. Leave about a 1/2" gap between the cradle and jack. Remove the four rear cradle bolts. You will see the cradle drop to the jackstand. It may not drop until you do the otherside.
13. Use your hydraulic jack to lift the cradle off the jack stand. Adjust the jackstand underneath the cradle so it can drop another inch. Alternate this procedure until the cradle has dropped 3 inches. If it won't drop, the front bolts haven't been loosened enough. (careful that leave enough threads in the front bolts to hold the front of the cradle on.)
Don't be alarmed if the mid steering shaft seems to pull down with the rack. It's designed to slide up and down some (I assume... If I'm wrong on this and it's supposed to be firmly in place, let me know.)
