Here's what your steering coupler might look like. This is a dangerous situation. If this coupler fails completely, you will lose steering control. (IMG:style_emoticons/default/yikes.gif)

By now almost all of them are probably bad from rubber degradation with age.
Those rag joints suck too, are they on all 914's? If my 75 has one, I'm getting that fucker out and replacing it with a u joint somehow someway. |

I replaced mine last year with an aluminum billet biscuit. No more rubber donut for me!

I replaced mine with a hockey puck (not kidding)
Its easy to find, cheap to buy and simple to drill. I will use a bruins puck on the next one so the new owner will have a bit of Boston to take with them. I reused the steel inserts that are (were) in the rubber donut and put them in the hockey puck. I ground them down a little to make them flush.. There is enough play in the system to loose the 1/8 inch. Rich |

They are very stiff, like polyurethane bushings when they disintegrate instead of wear like rubber since rubber can absorb impact........ IDK. I'd rock it for a while but would go metal or to a u joint. But it looks like metal would be ok, does not need to articulate much. |

Would a later model 911 coupler work? They sure look the same ...
As for "down right scarey", it's basically just a Hardy-Disk. Commonly used on a huge amount of automobiles for various applications. My 280SE Mercedes used one to couple the driveshaft front to the rear. They are used to reduce vibrations. I'm almost certain a 911 unit would fit and they're probably still available brand new ...

Its not brittle...it closes up on the drill when you are doing it and it smells like rubber. In the original unit there are steel sleeves for the bolts to go through so you are clamping down on those steel tubes. I used those, had to grind off a bit to get them flush with the puck...works fine. The bolts are dealing with the force, not the puck...its just a spacer so you wont feel bumps... Rich |

Just looking at it again...I only used two bolts so its directly bolted right through the hockey puck...simple.

Can the rubber coupler be replaced without dropping the whole steering rack?
I just put my front end back together and reused the coupler. It didn't look too bad except for some gaps around the metal sleeves. I'm now thinking maybe I should've replaced it while I was in there (except the Porsche dealer wanted $145 for a new one!). |

The plastic cover (missing in my first pic) is in the way. You'll have to pull the rack to get to the coupler. If the plastic is gone (cut it?) you might be able to do it with the rack in place.

I wonder if two beetle steering discs together would work, or does it have to be a single piece?
