Hi, new member here with a query. My 1997 Mk1 Eunos has developed a ‘chattering’ gearstick when accelerating. It does not happen on the overrun and disappears when I grip the gearstick knob. The noise subsides once everything is hot (15+ miles). I suspect that there is a plastic bush at the bottom of the stick which has become brittle and broken up (perhaps during recent cold weather) and this is allowing the lever to rattle.
Can any of the experts out there advise me whether this a serious problem & a solution?
Had the car about 3 months now. Great fun apart from this problem. Bought as a second car but now using it as my daily commute except when I need the luggage space.
The first link takes you to the download section of the forum, look for the one called “How to replace gear lever boots NA (MK1) & NB”
It’s worth doing the whole job. Para 16 refers to the nylon bush on the bottom of the gearlever, this may be causing your problems. The second link has links to the parts for the seals and another description of the job.
Mines doing exactly the same at the moment, again Nardi wooden knob.I am sure the knob is ok and I replaced the nylon bush and topped up the turret oil when I changed the gearstick boots last year. Easy to do so will check it again when I get a chance.
I am fairly sure it is the Nardi wooden knob at low temperatures that is vibrating. This morning it was mild and there was no sound , tonite it was a bit colder and the buzzing noise was back. As you say as soon as you touch the knob the noise goes. Well I held the gearstick below the knob to try to isolate it but it made no difference so the nylon bush I dont think will cure it. Once the heater had warmed the car up the buzzing from the knob went. The knob is tight on the stick so I will have to unscrew it see what else I can do to eliminate it. Sorry it was a bit long winded but hope it helps.
Replaced the boots & oil today & seems to have cured the vibrating stick for now. Mild here today so can’t verify your theory until the temperature drops again. If it is the knob I can live with that during the cold weather. The bottom boot was torn and the oil was the colour and consistency of a thick pea soup so the job was worth doing anyway. Also replaced the nylon cup which looked OK in fact although discoloured by the heat from the gearbox. So we wait & see.
Many thanks to all those who provided info & advice from.
You were both spot on. The Nardi gearknob is acting like a rattle in the cold weather (why only when it’s cold?). I’ll try to reglue the threaded core with Araldite.
Mike ,I have actually narrowed it down to the black ring at the base of the gearknob. I found that if you just touch that bit the buzz will go. Havn’t actually done anything to try to cure it yet but I imagine a bit of glue or silicone RTV might fix it.
