928 Steering Wheel Installation Pictorial Step-by-Step For Beginners
Years ago when I had a 1986.5, I swapped out the stock steering wheel for a new aftermarket wheel and loved it. After a year in my 1988 S4, it was time for a similar upgrade. A quick search here revealed Bill Ball's excellent steering wheel installation, and that was enough to remind me how I did the old steering wheel swap way back when: http://www.billsworkshop.com/P928S4/momo/momo_club4.htm .
However, I took a few more pictures so that a beginner can see what is involved.
You will need:
1. aftermarket steering wheel
1. Momo hub adapter for a Porsche 928
1. 27mm socket
1. socket extension
1. ratchet or socket tool
1. phillips screwdriver
1. 3mm hex wrench bar (included in Momo hub adapter box)
1. 8mm open wrench or socket (if turn signal box needs adjusting)
First, pull fuse #18 for the 928 S4's to disable the horn (it has power even with the key out). You'll thank me later! Pull back your carpet on the passenger side floor, remove or flip down your wooden fuse panel board cover, and start counting fuses from the top left until you reach the 18th fuse. Remove it and set it in a safe spot for later re-installation.

If your aftermarket steering wheel has a center pad, you'll want to remove it now (this steering wheel holds its center section on with 3 phillips screws).

Put one hand on each side of the stock Porsche center section and sharply pull it straight back to you in the driver's seat to remove it. Gently disconnect the single black wire from it.

Lock the steering wheel with the key out of the ignition, and use a long extension on your 27mm socket to easily remove the center bolt that holds the stock Porsche steering wheel onto the hub mount.
Leftie loosey. Counter-clockwise loosens!
With the 27 mm nut off, cautiously insert your ignition key, turn to run (not start), and straighten your steering wheel to match your straight wheels. Don't pull on the steering wheel! Now turn the key off and remove it, then gently pull the steering wheel toward you to remove it.
*the hub and steering wheel may still appear to be stuck onto the steering column after the 27mm nut is removed. Don't panic!
However, even then there will be a tiny bit of "slack" now that the 27mm nut is off. With the big nut off of the steering column, squirt in some Liquid Wrench onto the center shaft and then simply tilt the Porsche's steering wheel ever so slightly up, then down, then up, then down, etc...all while pulling gently on the steering wheel such that the hub "walks" itself off of the steering column/shaft.
No puller required.

Slowly slide the Momo hub adapter into place (tab at 9 O'Clock position!), noting that the top-center hex bolt hole is precisely at the 12 O'Clock position.
Place the 27mm washer onto the shaft, then hand tighten on the 27 mm nut and slide on the rubber column/hub cover.

Place your aftermarket steering wheel onto the Momo hub adapter. Align all 6 hex bolt holes in the steering wheel to the hub adapter. Note that the top hex bolt hole on the steering wheel should be in the 12 O'Clock position, of course.
Insert and hand tighten each of the 6 hex bolts in a cross pattern just as if you were properly installing wheel nuts onto lug bolts after a tire change. Once all 6 hex bolts are hand tight, then repeat the cross pattern to tighten all 6 hex screws.
Don't overtighten! Tight is fine, but don't crank down like the wrath of an angry God on them.

Connect your Momo Hub Adapter's black wire to your aftermarket horn button.
One wire is all that it takes. When the button is pressed via the center section of the steering wheel, the button makes contact with the grounded steering wheel. This completes the circuit to sound the horn (once Fuse #18 is reinstalled, anyway).

Reinstall your aftermarket steering wheel's center section. For this particular aftermarket steering wheel, that means screwing in 3 phillips screws from behind the wheel.

Re-insert Fuse #18. Press the center section of your new steering wheel. If the horn honks, then you are finished!
*well, you need to go for a cautious test drive to insure that the steering wheel is tight and aligned properly, that the blinkers cancel after you finish making a turn, that you have no rattles, that your horn doesn't honk on its own randomly, and that all is well and good, etc.

A few notes:
I used an el cheapo aftermarket steering wheel for this project. $68 here: http://www.migicute.com/sw94163bkl.html
The good news is that they delivered it fast and it was a precise fit onto the Momo hub adapter. The bad news is that it smelled like pungent industrial chemicals. Intolerable aroma.
I had to coat it in baking soda overnight, then clean it with Leatherique's "pristine clean" leather cleaner, and I needed to let it sit in the hot Alabama Summer Sun for 3 full days before the seemingly toxic smell was baked out.
This was a *very* different experience from the wonderful, new-leather smell that I enjoyed with my real Momo steering wheel that I installed onto my Ferrari a few years ago.
So, if you cheap out, your nose will pay. You've been warned!
Also, I found the Momo hub adapter here for $67: http://shop.vendio.com/crowderscusto...245/index.html

Nice writeup , the only thing i would add is that the turn signal switch should be checked for the proper depth , so the horn contact isnt smashed to the new hub, this will wear it out or tear the horn contact ring off.
To do this remove the trim strip ( 2 phillips screws) and the 2 10mm bolts and 1 phillips screw that holds the column trim under the pod. once this piece is removed then you can see where the new hub will ride on the shaft and where it will contact the horn strip on the TS switch.
To adjust the TS switch loosen the 8mm bolt thats in the clamp and slide the TS switch as necessary.
The horn ring does not have to be smashed flat, a light touch is all it needs , add some grease to the parts so they will last longer.
Refit the trim once the TS switch is tight
