Nismo GT Rubber knob rattle

[Whiplash Willy]

I have a 2nd gen B&M short shifter and a Nismo GT Rubber Shift knob. The knob rattles like crazy, and hums with viberation. I know its just the knob because when i take it off there is no rattle. Does anyone know of a fix for this problem?
I tried putting the tip of a rubber hose up in there so the threads would grip tight, and it dosn't help at all.

[TiNMAN]

do you have all the parts for it? tighten the top enough? are the threads on your shifter dull? i had no problems with my gt shift knob, it was the urethane one also. is it loose even without screwing the top down?? hmmm..

[trsilvias13]

can u show pics of this knob? i might be interested in buying one... never seen a rubber knob before

[blue109]

my shifter rattles, but its where it goes into the trans, not the knob. if both parts are tight i dont really see how it could rattle. does it feel loose at all? does it wiggle?

heres a pic from jspec. id recomend the shift-knob, it feels great. easy to remove to get the center trim/shift boot off.

The alen bolt up top is as tight as i can get it. The threads are good since both shifter and knob are brand new. When i don't have the rubber hose piece in, i can tighten it all of the way, it keeps turning, but it is tight. When i have the rubber hose piece in, i can get it really tight. There is absolutely no play in either situation. I am thinking part of it is all of the extra vibration and what not throught the B&M shifter. I don't see what else i can tighten, maybe i can use something to absorb some of the viberation? How did you guys install your knobs? Did you take it all apart, screw in the inner piece, then put the knob on and tighten it with the allen screw?

Its not the knob. Tape the C-clip at the top of the black plastic thing on the shifter...thread tape works best.

[Whiplash Willy]

When i take off the knob, there is no rattle at all even at high rpms, or at points where i hear the most rattling.

[XxJaPxOxNeEs23xX]

just try putting thread lock on it and see if that helps.


i have the metal one. wen its hot it freaken gets too hot ull burn ur hands. thats the only draw back to it but i like the way the shift knob design is.

I used to have this exact setup so I'd listen carefully to what I have to say. Even the 2nd gen b and m rattles. It rattles much less than the previous model but it still does. Because the Nismo GT knob has a hollow bottom, the noise from the shifter goes up in that area and resonates. What I did to get rid of it was to stuff some crap up in the bottom of the shiftknob to work as a sound deadening. I can't remember what I stuffed up there. I think I may have used tissue or toilet paper.

[blue109]

im also thinking it may only rattle with the knob on because the extra weight of the knob pushes the shifter down a bit, allowing the metal on metal contact. mine doesnt rattle unless i rest my hand on the knob, then it makes all sorts of noise.

you should definatly install the knob in 2 stages if you didnt. put the inner piece on the shifter first, and use some thread lock. there really isnt any reason to take this piece back off, so tighten the hell out of it. then you just have to use the allen screw to take the rubber part on and off if you need to. it shouldnt be able to rattle at all.

I wouldn't use thread lock....what happens when you want to change your oil?

Try either what Flybert or I listed. We both have the shifter...(I have not tried fly's method but it sounds like it may work)

Yes, do thx's method as well if you want to do it the right way. It'll take a few minutes more but it'll be worth it. If your a lazy bastard like me, do it my way.

[mjjstang]

i got same exact setup as you including second gen, and mine does same shit, havent checked if it stops when knob is off though,

[Whiplash Willy]

Thanks guys, ill try stuffing the thing and tapeing the c clip and keep you updated to what works.

i dunno i just gave a suggestion but thread lock does come off when u want it to. it just keeps it from vibrating out. and thers differnt strengths in thread lock.

I have the same problem with my B&M shifter/Nismo GT knob. It only really started to make noise right after I changed my clutch. It wont make noise at certain rpms or speeds...but it will rattle like CRAZY at 80mph...and its pretty annoying. I'll try putting a piece of foam or rubber between the knob and the thread part and see if that works. I'll keep everyone updated. I'm just glad to know I'm not the only one with this problem.
:x:

True on all points.

In zilvia "tradition" though thread tape is better.

ITS CHEAPER~!

:coold:

[Whiplash Willy]

I tried thread tape on the C-clip and the threads on the shifter, allen screw, and around the inner part of the knob (which screws into the shifter, that the actual knob is screwed into). I also stuffed the bottom with some paper towels. that decreased the rattle a bit, but it is still there. I am pretty much out of ideas as of now. Any other advice would be appreciated.

[420sx]

it rattled like a bitch in mine. i had b&m too.

switched to stock. perfect fit on my hand. nismo gt is for lil girls.

[Drunk Bastard]

I put a rubber gromit between the threaded metal piece that attaches to the shifter and the actual shift knob. I set it up so that the screw goes into the hole and it didnt make a difference at all. Still rattles at about 80mph. I'll try the T.P. trick tomorrow, but I doubt it will help. Anyone have any good incite? :2f2f:

I have an ebay knockoff of the B&M with that knob and it doesn't rattle at all
I love my $60 shifter , will do a write up after I get more miles on it
Is the bushing on the end of the shifter[in the trans] tight?

[crioten]

dont use thread lock...thats just dumb lol...

to properly get rid of thread lock you have to heat it up to something like 600 oF...i dont think the rubber can take that much lol...and you would prolly tear the shit out of your shift knob or maybe even snap the shifter trying to torque it off...

just turn your stereo up a bunch and deal with it :)

[Drunk Bastard]

ok, I've tried taping it, doing the TP trick, putting a rubber piece in there and ive taken the shifter off to inspect that it was sitting in there correctly...It STILL rattles extremely loud at 75mph. I never minded the quiet rattle from before, but since I've changed my clutch the rattle has got 10x worse. Anyone have ANY idea's on how to reduce vibration in the driveline? I dont think its the B&M shifter itself, I think it might be the tranny shaking. Does anyone have a B&M shifter and the nismo tranny mounts or any other type of tranny mount?

:sadwavey:

[thx247]

Is the little plastic piece on the bottom of the shifter still installed? Just have someone local look at it if you can.

[red240]

I've got an ebay copy of the B&M and the nismo knob and no rattle, The shifter is tight and works great!
I've had it on for a few months and no problems, not sure what is causing the the rattle but if the bushing on the end [trans] is worn it will cause problems

[Drunk Bastard]

I took the shifter off on sunday and inspected the plastic piece, cause i thought it was that too. And sure enough, it was in perfect condition. Like I said, this only happened AFTER changing the clutch. Before, it would lightly rattle (not enough to notice/complain about) but now it rattles like no other between 3000 and 3500 rpms'. Im gonna put my stock shifter back on and see if it still rattles. If it doesnt...well I guess I'll see if B&M will send me a new one or something...considering its not that old.

[MasterOFDrift]

what do you expect to happen when you get engine and tranny mounts that are decently solid plus a direct shift kit like the B&M? seriously there WILL be vibration and it WILL get worse as you go faster. Also you can not get rid of the vibration completely.

I have a B&M with a stock leather shift knob I get less vibration then when i had my momo or when i tried using the B&M shift knob but i still get vibration its quite normal when you get a direct shift kit.

when you modify your car towards more performance you will inevitably and definitely sacrifice daily driveability, depending on what type of person you are the lengths at which you consider drivability can vary, it is just something everyone who decideds to modify a car considers and is well aware of. so basically just get used to the vibration : P otehrwise put your stock shifter back on and call it a day.

[MasterOFDrift]

^oh and by the way why would you ever put thread lock on your shifter? unless you decide to not change your tranny oil and not take your center console off lol

[Drunk Bastard]

who put thread lock on? I certainly didn't

[MasterOFDrift]

^ sorry not reffering to you, reffering to the guy who suggested thread lock

[thx247]

Every time I've changed the transmission oil on my two cars the shifter makes more noise for awhile and then quiets down. Sometimes it takes 2-3 days, sometimes just a drive to work. I'm really surprised you're having such a rough time quieting it down.

[Whiplash Willy]

Well i have tried pretty much everything. I took off the c-clip on the shifter along with the lower boot. I put the stock knob back on and it still rattles. All bolts are tight It rattles prettymuch at all speeds, it is especially bad when i take my foot off the accelerator. The weird thing is, when i take off the knob, there is no rattle at any rpm or speed i have tested, unless i grab the threads tight. I will take out the shifter soon and see if the white washer is firmly on the shifter, and i think i will take the whole shifter apart and see if i can find a problem. But the rattle is horrible, and would drive an iguana insane, it is not just at high speed and rpm, but at most speeds and rpm. What a pile of shit.
