Hallelula!!!!! I have found someone who will skim drilled and grooved disks who is fairly local! I've only called about twenty places.... Touch wood, but it doesn't look like I'll be having to take a trip to EBC in Northampton. I'll post up details when done, I'm going in tomorrow afternoon. See what the runout are like before and after. Thanks Steve

I think its probably one of the bearings on the gearbox, likely in my opinion to be the input shaft bearing thats gone. I also have a very quiet whine, I'm 99% sure what most people think is the clutch release bearing (common fault on the 350Z) is actually the gearbox input shaft bearing. I had this before on my Punto and it was very similar to the noises coming from the 350z. When the clutch goes I'll be taking the gearbox off and having the input shaft bearing replaced. I have no noise at all in neutral with the clutch pressed in but get a rumbly/ additional noise when it is released. Hope you get yours sorted mate. Steve

Hi mate thanks very much. This is where it gets confusing it works perfectly with everything except for the Iphone. My sony MP3 has no issues. I would use that but cos its well old the battery lasts about 5 minutes and windows on my laptop doesn't support Sonicstage anymore. I'll take some photos when I pull it apart next time and send them over if I can't figure out whats wrong, maybe someone else can see whats wrong really appreciate your help. Thank you very much Steve

I'm still struggling to find someone who is actually willing to skim the discs. I haven't had any response from EBC as to if they can identify someone who is willing to skim them, I can't seem to locate a phone number for them either. Just for information the runout on mine where the problem is coming from is 0.36mm so to the naked eye looks like nothing but is a lot in braking terms. Spec for rears is 0.07mm and front 0.05mm. The root cause is hub runout caused by a bump to the kerb during the snow. Replacing all the parts isn't garaunteed to remove the problem completely because of the tolerances in the assembled parts so a skim may still be required even with a new hub carrier, hub, bearing and disks. I work in engineering and a lot of tolerance stackups are based on statistics and in some instances you will just be unlucky. A skim of the disks on the vehicle is the best solution if you are suffering any disk runout provided the disks are fairly new or you have enough meat left on them so they can be skimmed and won't go close to or below the minimum thickness. Obviously first check you haven't mounted the disks on a dirty hub! I'll let everyone know if I find anyone who will skim them up. Cheers Steve

Hi mate, Thanks very much, if I can't find anyone who will skim them up then I'll be stuck with only one route, new everything in that case I'll drop you a PM savings on parts are always appreciated Cheers again steve

Hi mate, I have considered fixing the underlying issue however this will prove to be very expensive. The wheel bearing would need to be replaced and it is also good practice to replace the hub as well. I've had experience in the past of just replacing the bearing to find it goes again a few thousand miles later due to the hub being out of round following removal of the old bearing. This should solve the hub run out issue but it can't be garaunteed because of the tolerance stack up of the associated assembly. I used to work in a car plant and disk skimming was done on some brand new cars. If the new bearing and hub etc did solve the hub runout however then new discs would be required because the ones on there now have got a thin patch caused by the hub running out for the last couple of thousand miles. So either way to use the existing disks they will need skimming and getting them skimmed on the car is the best bet because then they match the hub and run much truer. Hope this makes sense. Cheers steve

I still can't get my MP3 mod to work with my Iphone. I'm getting there though I think, I added two 32Ohm resistors as suggested by another member and it now detects that the Iphone is plugged into something so plays through the car speakers until you pause it then it stops working again. Only other thing I've noticed is the earth portion of my lead is live when you lick it you get a tingley tongue, I really don't know how I have manged this, it is only soldered onto the earth part of the board..... I tried licking the lead plugged into my hom eamp and this is tingle free . . . . nothing is ever easy or works first time for me.....

Hi Everyone, I hope someone can help me. Has anyone had their EBC turbgrooves skimmed on the car? I need to get my rear disks done due to hub run out on the passenger side from a knock on the kerb in the snow. However, I have tried 4 places I found on www.skimmydiscs.co.uk but no one will do them because they are drilled and grooved. Has anyone found any places that will do them? I'm based in Wakefield but I am now willing to travel cos I can't drive over 50, well I can as long as I don't use the brakes but need to get them done as soon as possible. I'm even considering going to the actual EBC place in northamptonshire. Does anyone also have a phone number for EBC because all I can find is an email form on their website and they haven't replied yet...... Thank you Steve

These are still available if anyone is interested. All boxed up and ready to go. Thanks Steve

Hi Zazur, the disk causing the problem on mine is running out a long way its clearly visible to the naked eye However the issue is quite a lot to do with the runout of the hub I have found. After I checked my discs I took them off and got the flatness checked where I work. The discs are all within 0.035mm except for the passenger side rear on its own it is out of spec but only out by 0.1mm. The hub run out however (at approximately half the diameter of the disk) is 0.15 thus at the outer edge of the disk this is causing the disk to run out by 0.30mm (assuming the disk was perfectly flat) however I know thats out by 0.1mm which gives a total runout of approximately 0.4mm. Since taking the original measuremnets I posted I have rotated the disk to its 'best' position and run out is down to 0.36mm way out of spec but I think with mine the biggest issue is the hub run out not the disc itself. Have you checked your hub runouts this could also be contributing to vibrations. I'll let you know how I get on after my skimming, I've found a local guy who ill skim the turbogrooves.

Well car got serviced but discs didn't get skimmed, garage were unwilling to do them because they are drilled and grooved and were concerned they would damage the machine. Bloody main dealers need a kicking!# Trying to locate somewhere else tomorrow!

thankfully its just not me, getting the resistors tomo so will feedback how I get on.

Well I bought myself a clock and base and checked my disc runouts, all was well until I got to the nearside rear . . . Nearside front = 0.03 mm Offside front = 0.05 mm Oddside rear = 0.08 mm Nearside rear = 0.45 mm!!!!!!!!!!! Car is off in Thursday for P2 service and Procut skimming see how I get on. I'll post up runouts afterwards, only getting rears done because fronts are in.

Excellent glad to hear its helping out the masses

Hi mate thanks very much I'll give that a go and see if it works, hope it does work I keep having a play and don't get nowhere. Cheers

Hi mate Im interested in the clear reflectors you have PM

Thanks mate, at least I now know its possible. I'll keep investigating Cheers Steve

Quick one, has anyone managed to get an IPhone to work with a Ghetto MP3 mod? I have got everything else to work with mine, MP3 player other phones etc but neither my iphone or any of my mates will work with it. You connect the lead and the Iphone does not recognise it is connected to anything so plays the music from its internal speaker. Really can't figure it out. The Iphone worked with the same cable attached to my home amp no problems attached to the bose no chance. If you start the ipod function playing then slowly insert the cable you can get sound to come through the car speakers for a few seconds but then the Iphone stops the music playing..... Plug it in fully before you start and it just plays through the internal phone speaker??? Realy confused. . . . any help appreciated. Cheers Steve

I've been told if you take your keys and log book. To the Nissan garage provided they are still the standard ones they can order you the right key. My weekend has just been topped off by realising I've lost mine gonna call Nissan tomorrow. To find out what's what. I think I left it on the wheel nut last week after putting the wheels back on. WHOOPS And now some magpie has probably got it as a nest ornament! First the girlfriend called time on us, then Wakefield got knocked out of challenge cup and now have no wheel nut key! What a truly awesome weekend!

GT4 Zed I think you are right I've measured the hub run out and it is out of spec. At the end of the day the wheel bearings amd hub wear which seems to be the root cause. I had one of my disks checked on the CMM at work for flatness and it is less than 50 microns out of flat which if mounted to a brand new car would have no problems. The problem for me seems to be caused because my hub runs out by 150 microns, three times the limit for the assmebly with the disk and thus the root cause of the vibrations. A pro-cut skim should fix the problem, I'll let everyone know how I get on when sorted. Thanks Steve

Thanks for your reply mate much appreciated. Right I have solved my issue!!!!! Problem was a few things: 1st and major problem was a small bit of solder ad dripped and was connecting two different parts of the tape deck board so I did have a short circuit but not from the cable was from elsewhere. 2nd and major problem was that the cable I have used is quite thick and when it was wedged between the HU base panel and tape unit it was stopping the tape from turning hence the 'error' message. Everyone be aware of this I just re-routed the cable and sandwiched it somewhere else to stop it getting pulled. 3rd and finally the IPhone is FAR too clever for its own good. Any other MP 3 player (I tried 2) work with the ghetto mod I have done however the iphone somehow knows its connected to the ghetto mod and decides it doesn't want to recognise there is anything plugged into the headphone port!!! So plays the music through its internal speaker. When my IPhone is connected to the hifi downstairs and the amp in my bedroom with the exact same cable that is now in the car it works fine! But not with the Ghetto mod. I have no idea why this is..... Has anyone got an IPhone working with theGhetto mod??? Thanks Steve

Hi Mic, yes it was me down at RS on saturday, how did you go in the end? Wish I could have stayed around but had prior arrangements. Good to meet you hope it all went well and the drive back wasn't too stressful, nice plate by the way I've bought a clock to actually check the runout properly instead of using feeler gauges and the caliper, it was taking ages! But based on feeler gauge measurements its gonna be time to go to a procut centre. Thanks Steve

Hi Guys, Right I've been trying to do this mod for the last couple of days and I just can't get it to work. Basically I've followed Alex's excellent guide and got my cable soldered in, I tried it the first night and I couldn't get any sound to play. So tonight I removed the cable checked it works with my home amp which it does just to verify I didn't have a fubbared cable. So soldered back onto HU and checked continuity between channels with a multimeter. Set my multimeter to continuity mode and it shows a large one on the left of the display when no continuity is present and reduces to 0 for a 'perfect' connection. When the unit is in the car with the ignition off or on the table I get good connections between left channel on 3.5mm jack and left channel on tape deck board and no continiuty to other channels, same for earth and right channels. When checking against the correct channels i.e. left to left, ground to ground etc I get continuity readouts of 003/002. However when I turn on the ignition and check across channels I get a continuity readout of 548 left to earth or right to earth. I also get 548 if I check the left or right channels to the HU metal case. The HU case when checked against the earth shows a continuity of 003, Is this correct? I don't think I should be seeing any continuity between the left channel or right channel and the earth and I don't think the case should be an earth should it? Also tonight when I tried it and put the empty tape into the tape deck the unit played forwards for a few seconds then back then ejected the tape and said 'error' on the display. Tomorrow I'm gonna remove the cable and try the headunit on its own I hope it all works OK Whilst the HU has been out I've done the fix for the left channel on the CD player so hope I haven't knakered anything or put it together wrong . .. Hope this all makes sense, I think I've got a short circuit somewhere . . . .
