A grind sounds like a bearing. Where it is though is anyones guess. Suggest jacking front and try turning various parts to find the culprit. A stethoscope helps.

+1 on the visual inspection, but they are mighty heavy to push The additional resistance of the transfer case etc. makes a difference!

Just came across this one - might be the same issue I've had since I bought my M35 last october.

I did some tyre swapping early this year (well, swapped different wheels with the spare to try to identify the problem) and it seemed to me that it was just purely tyre noise in my case.

However, ~6 months later and the noise has been slowly getting worse. Hard to say if it gets louder with speed, if anything its loudest around 30-40km/h and kind of stays fairly constant after that.

Lately its started doing a really low-pitched grinding noise around 10-20km/h and this noise will continue if i stay under 20km/h. The vibration can be felt through the car, although more through the floor at the front / steering etc.

I was originally suspecting wheel bearings when I bought the car but I'm not so sure. When I put the spare wheel on the front the noise almost disappeared. Its definitely speed related which just points to anything AFTER the gearbox I imagine.

Its booked in for the 100,000km service this week - might get the mechanic to sus it out while its in there.

Other symptoms include when cruising at say 60km/h, sometimes it will all of a sudden feel like the brakes are on and it starts slowing down quicker than normal - feels like the gearbox shifts to a lower gear which is strange, normally at this speed it will be in 4th or 5th when cruising.

And yet another symptom is the sensation that something is "slipping" either when changing from reverse to drive or if just slowly taking off up an incline. This doesn't occur when driving normally though...only when first taking off from standing still.

Well I have the verdict on mine already - the mechanic just rang and confirmed it is just the tyres. He said they had it on the hoist and the wheel bearings seem fine. This is the same as what my dad and I diagnosed on it about 6 months ago so I'm happy now.

The tyres are really ribbed, particularly on the inside. The tread is just getting sharper and sharper edges on it the more its worn. So now its making a shudder at 10-20km/h and also the whining noise as you go faster.

So in some ways its a good result but now I've got the choice of either drive a nice car that handles like crap (and sounds like a council bus) or hand over ~$700 for new tyres.

I really really want new tyres now - this has been driving me up the wall for the past 10 months!!

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
