DIY: Fix for PWJDM Shift Knob Rattle
 

I know from reading other posts from Z owners with the Password: JDM shift knob there tends to be a rattle when the engine is revving. I did two things that cured it:


Next, get a rubber grommet like this one (cost me less than a dollar at a home improvement store):

Place it on the shift lever (at first I tried it under the shift boot, but that didn't work. But here's a shot of how to remove the trim around the shifter anyway, then the grommet on the shift lever:

Remove the little collar inside the shift knob (I think this is the source of most of the rattling):

Reinstall the knob, and you should be rattle free!

The grommet is rubber, 1" in diameter with a 1/2" hole. It is 1/4" thick. Sorry for leaving this out the first time!

nice dude!

Nice writeup dave!

Thanks guys! The rattle is completely gone with these minor changes. I really like this knob for the Z, not only for how it looks. Because the seat is below the shifter height on the Z, having a knob of this type works very well (compared to a larger ball type knob, which I've had on all my cars where the seat height is equal to or higher than the shifter). :tup:

Awesome! +rep to you!

I'm about to receive my PWJDM shift knob and was already worrying about this..

Thank you!

i installed my knob while i was doing my audio install and also removed this:

i believe any rattling anyone got before was due to this little washer type thing. ive never heard any rattles, so i dont believe you really need a grommet either..

Good to know, Chops! I like how the grommet makes a tighter seal with the shift boot. But if it doesn't do anything to stop the rattle, then removal of that collar/washer is an easy fix:tup:

Nice DIY.

I did basically the same thing when I got mine this past summer. Instead I just cut up an out an old bicycle tube into a couple pieces about 1/2" long. Haha, didn't have a washer at the time. Anyways it works great!

Very creative! I spent about 20 minutes looking at different washers and grommets a the home improvement store. I'm not complaining though. Stuff like that is like therapy to me.

I just installed my PWJDM shift knob and followed chops advice to remove that silver wahser thingy... No rattle at all.. I bought the red one and love it..

^looks great!:tup: If I had a red Z, I would go with the red knob, too. Adds a nice pop to the interior.

So it looks like the collar/washer is the culprit. Only follow my grommet advice if you want to also achieve a tighter seal between the knob and the shifter boot.

I got the white delrin one... I like it, but which it was a bit shorter.

Is there a DIY on how to remove the knob, I imagine it just screws off but I don't wanna damage the stock one
