Expand All | Collapse All | What is it about this Vibration Thing?I originally joined the UK 300ZX forum because I found a recent thread about trying to cure a vibration which appeared to be down to the propshaft.Many hours in front of the PC and hours under the car later (this is a lie - I may be able to find letters on a keyboard but am grossly incompetent with mechanical and electrical trickery. I leave that to others!) it became clear that: 1) everyone gets this vibration sooner or later Disclaimer: I am not technically qualified so if you take any action based on this information, you do so at your own risk. I accept no responsibility for the authenticity or validity of the items or articles linked from on this website. The story starts here...I bought my 1989 300ZX TT 2+2 in August 1999. At the very beginning, I noticed an intermittent vibration which appeared to be related to road speed. Not engine speed, road speed. It felt like there was a lump on one of the tyres. drrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr and so on. OK, I thought, new set of tyres, balance the wheels - that'll sort it. Hmmm - bit better but nothing to write home about. At the time, I had all my servicing done by the excellent Slough-based Nelson Mandela, so simply told them to fix the vibes. They tried several times quoting heat shield vibrations amongst other stuff then hit a blank wall. They contacted Nissan Japan for advice and were told "change the prop shaft". Given that this was estimated (at the time) at £750 + VAT + labour, I thought ****. Let's try something else before doing that! The Z-Club mag ran a letter from someone who had a similar sounding problem on a late 1991 UK Silver 300ZX TT. He pinpointed the problem to the UJs on the propshaft. April 2001
He'd forgotten I was coming so that got everything off to a good start. The vibe got better (less pronounced) but no major change. Hmmm - what next? I asked Mr Mandela to speak to Mr XXXXX to find out what had been done - no satisfactory response from either so put to one side for a bit. February 2002 Find the first relevant thread http://www.300zx.co.uk/forums/ubbforum/Forum6/HTML/000227.html There are pages on pages of good stuff from a lot of good people. Some of the ones I understood (vaguely) are included: Cookie first posted with a story about a bad centre bearing and clicking front u/j being cured by a 1 piece propshaft. February 2002 and a bit Cos recommends might be wheel-based March 2002 Colin from V-Tech had discussed this with a prop-shaft place from Luton and they, too, said to do the gearbox mount first. So I ordered one from www.japarts.co.uk £48.31 + VAT from J-land. Warning: it looks easy to get to but if you miss the turn there is no easy way to get back without a guided tour of Hendon or somewhere. And when you get there, nowhere to park either (well there is, but it is very crowded indeed.) My advice? I wish I had taken their offer of next day delivery but that would have cancelled out the saving made on this one small part. OTOH I would have had 2 hours of my life back! Fri 22 March 2002 There is a marked (positive) difference but still not perfect. The idea is to have a few days trundling around to quantify the improvement and then decide what to do next. 29 March 2002 Well, off to the Forum meet in Solihull on Saturday (good excuse for a long blast) so let's see what the boys have to say. What Next?
In view of his happy experience, I am very tempted to follow antleeds to those chaps in Bradford.... |
