Hey gurus, was replacing the steering wheel on my Nismo and my friend said this part was not found on his T.E.

 

Even the core on the new steering wheel had to be threaded for the screws that hold this part on.

 

What is this part and what does it do? There are no wires, or sensors next to it. We're thinking it's a weight? but the

weight is towards the upper center of the wheel.

 

Thanks in advance.

i'd think either a weight or magnet? googling "920a steering wheel nissan" shows it's a common piece in their steering wheels. i don't remember seeing that either when i swapped my wheel out.

I can't find it in any other GT-R steering wheel pictorial or reference.  Although the mounting holes ARE there. It is ubiquitous to many other Nissan's as you point out.

 

Looks like either a resistor or capacitor to me.  Maybe an anti-static feature?

thanks my people. I have no idea, but I definitely insisted on this OEM part to be put back on. It's gotta do something or else it wouldn't be on the Nismo models.

 

Does anyone know If I should replace the alcantara on the OEM wheel or just leave it alone? It's gotten worn out on the left side at about 9-10 o clock position, it's obvious i'm a left handed dominant driver. :P

Vibration damper.

 

How it work?

 

Why on some models and not others?  Or more importantly, why do all models have the mounting holes and they are not used on some and used on others?

 

Just asking - Since I didn't know and always trying to learn.

hey people, to this day, I still have no idea what this part does.

 

matter of fact, a very knowledgeable Nissan Parts person has no idea what this is!

 

Have I found the hidden, secretive, elusive part??

Interesting looks like it’s a damper as mentioned above.

I see some other vehicles use it to negate vibration frequency in certain Hz ranges.

Why one would have it and another wouldn’t, maybe that’s in the final shakedown ?

If you remove it do you get any wheel shake at certain rpm or road conditions ?

didn't even try it without. I figure if it were there to begin with, who am I to not use it.........(no sarcasm)

How it work?

 

                     Adding weight would change the natural harmonic frequency of the wheel, vibration and such.

 

Why on some models and not others?  

 

                     May be something about the nismo causes more NVH through the steering wheel?

 

 Or more importantly, why do all models have the mounting holes and they are not used on some and used on others?

 

                   May be they anticipate the possibility of needing this so they always have a provision for it in the steering wheel casting?

 

 

 

Just asking - Since I didn't know and always trying to learn.

 

 

                  I'm just guessing.  But adding a weight will definitely change the "vibration" of the overall piece.    Or, maybe it's a counterweight to change the feel of the steering wheel?  It is off center after all.  Be neat to do a back to back comparison on same road with it off and on the same car.
