George Dredd Posted May 22, 2011 Share Posted May 22, 2011 Hi guys, I need a bit of advice- following on from my previous post 'aaaarrrgh please help' I reported a rattle from my gearstick which happens between 4.5k and 5.5k revs, nobody could seem to diagnose/guess what the problem could be.... Well today while driving I found that if I apply a small amount of pressure to the gearstick it stopped, i.e if I was in third gear, I push the gearstick a tiny bit towards the stereo and the noise stopped, let it go and the rattle continues, I called my mechanically minded mate and he said it could be the gear linkages, can anyone confirm or deny that this could be my problem and if it is can you tell me if its a big job and a rough idea of costs. Thanks. Quote Link to comment Share on other sites More sharing options...
M13KYF Posted May 22, 2011 Share Posted May 22, 2011 is it a aftermarket gear knob, it could be a bit loose and just need tightening Quote Link to comment Share on other sites More sharing options...
George Dredd Posted May 22, 2011 Author Share Posted May 22, 2011 Yes I do have an aftermarket gearknob and coincidently the day I fitted it was the day I first noticed it rattle, the thing is my mate said to me on the way to japfest he could hear the rattle, but I could not hear it, I got the knob from japfest and fitted it while I was there (not using the grips and rubber method ) the old knob came off really easy that's why I continued to replace it. Anyway, on the way home I noticed the rattle and my mate said that is what he was on about before. I have tightened the new gearknob by hand and it is tight but I don't want to over do it, especially if I have damaged my gearbox in anyway. I suppose I could put the old knob back on and see if it still happens. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted May 22, 2011 Share Posted May 22, 2011 Could be a number it issues causing this, however the main culprit is the rubber O ring in the base of the shift knob, failing that the bushes in the base of the shifter where it hooks up to the transmission linkage. As usual all in stock Alex. Quote Link to comment Share on other sites More sharing options...
coldel Posted May 22, 2011 Share Posted May 22, 2011 I got a gear knob from KTA and when I put it on i heard an annoying rattle which only stopped when I gripped the gear knob hard (ok queue the jokes...). Anyway my dad had some white tape (cant remember what he said it was) but he wrapped it around the gear stick thread then put the gear knob back on and viola, fixed.

mattbowey Posted May 22, 2011 Share Posted May 22, 2011 there is a small metal piece within the standard knob which will remain when the knob is removed. check that's not still sat there. you'll have to take the new knob off to check. if it doesn't fit tight in the new knob it may be causing the issue.

leonk Posted May 22, 2011 Share Posted May 22, 2011 PTFE tape, plumbers use it as well. Its for sealing threads Quote Link to comment Share on other sites More sharing options...
George Dredd Posted May 22, 2011 Author Share Posted May 22, 2011 Thanks Alex, could you tell me prices for these bits and is it something I could do myself? Or is it a trip to cougar store? Does it sound like a biggie? I' m worried now Quote Link to comment Share on other sites More sharing options...

Does it sound like a biggie? I' m worried now If the problem only arose after you swopped out the shifter knob then more than likely the O ring will still in your old knob. Have a look and if it is, then simply transfer it to your new shift knob. If you still have issues then just give me shout back. Quote Link to comment Share on other sites More sharing options...
coldel Posted May 22, 2011 Share Posted May 22, 2011 Sounds a bit daft, but have you tried putting the old gear knob back on see if it still does it? Quote Link to comment Share on other sites More sharing options...

Not daft at all mate, anything's got to be worth a try, but no I've not replaced it yet because I don't have any grips, and want to do it properly this time, just incase I have damaged something.

George Dredd Posted May 22, 2011 Author Share Posted May 22, 2011 Ok, I have my knob in hand. Is this the rubber o ring you mentioned that is shoved right inside the knob? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted May 22, 2011 Share Posted May 22, 2011 Might be. The inside of the oem knob is made of rubber and the threaded part of the shift lever screws into this, however there is an independant rubber O ring which acts as an insulator. It is circ 5 mm deep. Have a poke about inside the oem shift knob and see if you can dislodge it. Alex. Quote Link to comment Share on other sites More sharing options...

George Dredd Posted May 22, 2011 Author Share Posted May 22, 2011 Cheers mate. Good to see someone else from leicester here we may have passed crossing over queens road about two months ago, we gave each other the zed nod. Was it you?

That's it mate now go fit it to the new gearshift knob and hopefully your noise will be gone. That little bad boy is actually an item that Nissan recommend should not be reused however at circa £14.00 a pop it is worth a go Alex Quote Link to comment Share on other sites More sharing options...
cmck13 Posted May 23, 2011 Share Posted May 23, 2011 I fitted an after market gear knob last week and had the same issue, however mine was the steel collet ring that you have in your photo. In my case my new knob wasn't bottoming on to the ring and hence it vibrated like a bell, take it off and see if that does it, don't forget its not unusual to fit this ring the wrong way round.

George Dredd Posted May 23, 2011 Author Share Posted May 23, 2011 Hi guys, just a quick update on the rattle, hear are the things I have tried so far 1- fitted the rubber o ring 2- fitted metal ring+ rubber o ring 3- re fitted the oem gearknob 4-re fitted the aftermarket gearknob None of the above made any difference- there is still a rattle Anymore suggestions? Thanks Quote Link to comment Share on other sites More sharing options...
George Dredd Posted May 23, 2011 Author Share Posted May 23, 2011 Oh and just to clarify, the rattle sounds to me like it is coming from the gearstick and not the gearknob. Quote Link to comment Share on other sites More sharing options...
M13KYF Posted May 23, 2011 Share Posted May 23, 2011 are you sure the gearknob is tight enough. maybe you have loosened the leaver Quote Link to comment Share on other sites More sharing options...
George Dredd Posted May 23, 2011 Author Share Posted May 23, 2011 are you sure the gearknob is tight enough. maybe you have loosened the leaver The gearknob is tight enough that I can't do it any tighter by hand, also when you say loosened the lever, do you mean I may have loosened the actual gearstick itself? If so what do I need to tighten it?(dont want to damage anything) Quote Link to comment Share on other sites More sharing options...
M13KYF Posted May 23, 2011 Share Posted May 23, 2011 yes, I know you have to be careful with the gearstick when removing the knob. Maybe alex can advise on tigthening the stick back. It does sound like a loose knob to me though. Perhaps you've got weak wrists and by hand isn't good enough Quote Link to comment Share on other sites More sharing options...
