I'm making my list to finish up the front end and I'd like to replace the steering coupler, but don't want a poly/solid one. Is there a rubber one available somewhere that I just haven't found?

Old factory stock.

Sometimes you have to add them to the cart and order before you find out if they really have them or not...

I was just showing a possibility.  eBay is another.  He has a part number now, hit the Google..

Thanks, guys. Part numbers are good. I can do 32.75+shipping, if still available.

I've kept a link to a 2010 post on this site about Nissan rubber bushing part numbers by Mike W. It's been very helpful.

 

 

I learned the very hard way, poly sucks on that application.  Be sure and make matching marks with a Sharpie before you take that apart.  Another lesson I learned the hard way.

What... You didn't like Nissan's version of a Rubic's cube?

what is wrong with the poly?

Poly transmits a lot more vibration then rubber does, when installed in the suspension some of that vibration is soaked up by the drivers seat foam, but on the steering wheel it transmits directly to the hands which can get tiresome and irritating on long drives. For sure the steering will feel crisper in turns with poly but it is a trade off.

I installed a solid nylon coupler and it lasted one season before I replaced it with OEM rubber, much nicer on the arms.

Way too stiff for a road car.  Would be good on a track car I suppose.  I put one on my 280 when I rebuilt the motor.  The wheel was twitching constantly, put the old rubber one back on after a month or two.  I couldn't imagine having one on a lighter 240 with the original wheel.

Ha!  My problem happened when the splined rod that connects to the steering wheel slid out of its engagement.  I just guessed at it and slid it back up into place.  Went to the alignment shop and he said the front tires were almost 2 inches off.  Bad guesstimate. 

 

Someone long ago replaced my coupler with one made of solid aluminum.  I have not driven the car over 20 MPH yet, so I haven't experienced the vibrations.  I may have to look into a softer one someday.
