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)

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.

This is certainly not what I expected down here.

That works fine.

I make engine mounts for 3rd gen watercooled VW's out of hockey pucks.

Buck a puck, can not beat that.

They have held up to 500+hp as well before.



You know on second thought i can see it working but I worry about the torsional force they would be subjected to. 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.

A hockey puck is rubber or some sort.
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...

I have drilled through them as well to make engine mounts, and have subjected them to a fair amount of power tugging up on them, as well as pushing down on them under acceleration/launching.

Think a shear mount, like body on frame for a truck/car. Same sort of up/down forces, just captured in a housing, rotation limited by the design. (Accounting for a transverse motors tendency to rotate fore/aft under accel/decel)

I am not sure of a hockey pucks exact properties, but they always felt much closer to polyurethane, perhaps simply due to the durometer rating of the rubber.


But what I do know is I have destroyed poly bushings, because they are too stiff to take certain impacts, and over time they start to tear, especially from torsional forces.

It would be a bad thing to have that happen here over time.

Whether or not a hockey puck would do it I do not know, but it is still better than an ancient factory rag joint.

I had one of those on my modified E30 and you had to drive around it at times, such as 9/10 of the limit. Flexible rubber disc between your wheel and the rack & pinion. That was a car from 1987, I can only imagine how bad a lot of them are on vehicles over 10 years older.
