FD Power Steering FULL manual conversion write up
Mods, posting this here b/c if anyone in the NE wants me to do it for them... plus i figure it was relevant to share, also in the 3rd gen section
ohh theres a price break for the NE guys
The topic of this has been gone over a few times and ill include links to a few of the threads for those thinking if this is right for them or not. I did this on the Rack of my red FD, which is finishing up heading into purpose built drag car. SO there’s no PS pump, so might as well not fight fluid in the rack if I don’t have to.
This write up will not be in full detail since my hands were covered in grease and if you have enough talent to get the rack out, you’ve got more than enough to do this conversion. I alredy used my brake bleeding vacuum pump to suck the rack what I thought was dry while turning the wheel. The rack still had over a quarter bottle of ps fluid in it….
The rack is held on to the sub frame with 4x 14mm bolts that go from the bottom in. Don’t sweat having a inner tie rod tool as once you have the rack off you can get them off much easier than while still on the car. Getting the tie rods off you can use a tie rod fork (10$ at pepboys) or if you hit the area on the spindle right around the tie rod it pops right out. But the fork will be the easiest for most on here. The Quill come off from the steering Colum once you loosen the 12mm bolt holding the spline shaft. A 12 and 14mm wrench will take the hard lines off the rack. You don’t have to worry about using a tubing wrench, there not in there super tight.
I’m going to start this write up from the rack out of the car, with all lines and inner tie rods removed.
Should look like this
On the flyingmiata site they remove the carrier first, I personally leave this to last just for shaft support reasons.
First things first, remove the dustcap (pulls off) and under the lovely peanutbutter colored grease there is a C clip remove this C-clip
Next turn over the rack, and remove the cap on the bottom (think it was 22mm) this will expose the quill retainer nut.

Remove this nut. You don’t have to worry about the Quill falling out b/c the carrier and the lower bearing have a pretty good hold on it.
Next flip over the rack, you are now going to remove the large lock washer around the large hex nut. (I used channel locks since my ¾ in drive with all the big boy sizes was forgotten @ home.)
Now unless you actually have a hex drive that large its time to fab up a SST
Amazing what a extra lug nut, random bolt and MIG welder makes ; )
Remove the large hex nut, under which will be a spring and the carrier.
Now move on to the left side of the rack, there is a little eyelet in here is where the retainer wire is.
Turn the end cap counter clock wise and you will see 1 end of the wire comes up and out of this access port. Keep turning counter clock wise until you get it all the way out, the other end has a small hooked tip that holds it onto the retainer, comes right off…
From there a few light taps around the edges with a small mallet it comes right off.
You into the home streach,
Tap the quill (on the bottom where you removed the retainer nut, and it will come right out (have a hand on it so you don’t drop it)
from here you going to have find something sutable to go in the side of the shaft by the quill so you can tap the rack out the far end. There is a small seal in there that needs some persausaion to come out. I used a piece of Almnium rod as to not damage anythgin.
Now using a suitable cutoff tool cut almost all the way through this, its hard steel so don’t think your going to get through it with a chisel with ease
Should look like this when done
There’s 2 ring retainers you can pry off
Now hit the parts washer, or if your not blessed with one clean off all the old grease the best you can.
On the flying Miata site the re-lube b4 putting it back in, personally I put it back in then re-lubed.
Re assembly is nearly identical to removal, I swapped the steps a bit but..
1- steering shaft back in
2- quill
3- quill retaining nut
4- C-clip on top of quill
5- Carrier, spring, hexnut (forgot the torque specs but don’t make it tight… turn the quill with your hand to find the right tension for yourself. You can make it easier or harder it turn the rack. I went a bit tighter since ill mostly be driving in a straight line ; )
6- Pipe cap that covers quill retaining nut
7- Retaining cap and retaining spring ( instillation is just opposite of removal, just put the little hook in the hole and go counter clockwise until its all in)
8- dust cover
reinstall tie rods, reclamp boots
Cut the hose ends off and fill them with a bit of weld….
TADOW you’re done….
I know Manville Charges 270 for this but I think that’s not deducting 50-60 for the core, and they clean it up. I don’t know if that includes shipping or not. But ill be happy to do it for 125 plus shipping. Since I have mine off the car for at least a week or 2, turn around will be 1 day. After than 2 day max turn around time for anyone who wants it done.
Ill do the full conversion, re-grease everything, weld all the nut holes, clean the whole rack, and do a little touch up where it’s needed. You can send it with or without the tie rods, if it needs a boot or anything you’ll be paying whatever Ray charges me.
Any Questions feel free to post up

As promised
For the quill you need to have a bearing splitter, disassembly is outlined in the FSM, after you get the upper bearing off its just moving down the quill, yet again I got ahead of my work. Little TIG on both sides : )

Sorry it has taken me so long to get back to this thread. I ended up moving to Massachusetts and its been crazy for the past 6 months. The toughest part is most of my shop is still down in New Jersey. So I’m limited in the amount of fabrication I can do right now.
But hope is not lost; I spoke with my shop foremen who use to do about 60% of the rack conversions for me. And he’s able to do as many as I need. So if you still need to have the conversion done let me know and ill get everything in motion.
pics were uploaded tio the test section, but i have them on my laptop so i can send them to anyone who needs
