An EF manual steering rack is a very simple device. I will assume you already know how to remove/install the rack since you have to do that anyway.
To disassemble the rack, the first thing you're going to do is remove the boots that cover the inner tie rods. Then you'll remove the inner tie rods. If you are replacing them, you only have to remove one side (the rack will slide out in either direction). There is a lock washer that needs to be bent out of the way, then you'll use a 22mm wrench and a 17mm wrench to unscrew the inner tie rods from the rack. If you don't have a 22mm wrench, a 7/8" is the same size.
Next you're going to remove the rack guide screw (aka adjuster nut). It's a 14mm nut but it's surrounded by a giant 40mm lock nut. Honda has a special tool for the lock nut (P/N: 07916-SA50001), or you can use channel lock pliers. When that's out, a spring, washer and the rack guide will fall out.
At this point you will pry the pinion dust seal out (replace, Honda P/N: 53426-671-003) and remove a snap ring that holds the pinion in. Lift the pinion/bearing assembly out and then the rack will slide out of the case.
At the passenger end of the rack, there is a nylon rack end bushing. You'll want to replace this as well (Honda P/N: 53430-SH3-000). You'll probably want to hose out the empty gearbox to remove all the old grease and dirt. Use new grease on all the components before installing.
