START!

For my conversion, I used Attain front conversion hubs, and S14 Silvia Q's SE rear hubs.

INSTRUCTIONS: REAR
Throughout these steps, use WD40 wherever necessary, and be sure to neatly secure all bolts/washers/etc while they're off the car. Use eye protection - you only get 2 and they're kinda fragile.

Step 1: Park vehicle in gear, lift and secure (via lift or jackstands)

Step 2: Remove wheel(s) from the position(s) you'll be working on.

Step 3: Using a 14mm wrench, loosen caliper, then move aside.


Step 4: Using a 17mm wrench, loosen caliper bracket and move aside.


Step 5: Remove rotor and set aside. If rusted to the hub, thread a bolt into the rotor to push it away from the hub, or use a rubber mallet to break it loose.


Step 6: Remove cotter pin and axle nut cap. FSM says to use a new cotter pin, but I never have.


Step 7: Using the 36mm impact socket, remove the axle nut (this is why we parked it in gear). You can use a breaker bar and 36mm socket, but impacts make life so easy.


Step 8: Remove rear shock/coilover (17mm bottom, 12mm top x 2)

Step 9: Install hub puller as below, and use it to push the axle away from the hub.


Step 10: Loosen and remove the 4 19mm bolts holding the hub to the spindle. The brake dust shield will come loose when you pull the hub off. Now is a good time to replace/mod/remove it depending upon your braking needs.
Reinstall new 5 lug rear in it's place.


Step 11: Assembly is the reverse of disassembly. Use the FSM and torque wrench to tighten everything to spec.


Step 12: Install your 5 lug wheels!


INSTRUCTIONS: FRONT (conversion/S14)

Step 1: Park vehicle in gear, lift and secure (via lift or jackstands)

Step 2: Remove wheel(s) from the position(s) you'll be working on. (Remember to loosen before lifting fronts).

Step 3: Using a 14mm wrench, loosen caliper, then move aside.

Step 4: Using a 17mm wrench, loosen caliper bracket and move aside.

Step 5: Remove rotor and set aside. If rusted to the hub, thread a bolt into the rotor to push it away from the hub.

Step 6: Using flathead screwdriver, pry dust cap loose and set aside. Remove cotter pin and set inside dust cap.

Step 7: Using 30mm (32mm for S14) impact socket, loosen spindle nut and set aside.

Step 8: Remove hub. Hub puller may be required, but mine slid straight off. Be sure to not the orientation of the key spacer inside the hub hole.

Step 9: Use a screwdriver and rubber mallet to tap the rear dust ring off of the OEM hub. Use the rubber mallet to replace it onto the conversion hub (or OEM hub if S14/necessary)

Step 10: Place new hub onto spindle, replace key washer, bolt down and cotter pin. Check for freeplay in the hub. Tap dust boot back into place.

Step 11: Reassemble brakes (may have to push piston(s) back into calipers).

Step 12: Mount wheels, pump brakes before starting car, start up, test brakes and drive away.
