Does anybody have a part number? Found them online for $150 each (!) but I only suspect that it's wheel bearing (could be diff') and if I replace one, I need to replace both... not keen to spend $300 chasing a noise...

Make sure it's not tyre noise - I had a friend who went and bought a set of bearings for her 40th Anniversary R33 GTSt after I bet her (should have put money on it too) that it was her tyres. My sister had the same tyres on her car (Maxxis MA-Z1's) and they are noisy as f*ck! Workshop swapped wheels and tyres with an R32 GTR that they were also working on at the time, and it was much more quiet.

Get hold of the suspect wheel and give it a solid shake, you will soon find out. Wheel bearings sound like a little steam train in the corner of your car, with little or no associated shudder. I first heard mine as a growl at really low speed (walking pace or less). Still drove it back from Apollo Bay to Melbourne then back to Adelaide before I worried about it, by then it had diagnosed itself.....

When you go to buy the part, Just Jap. Why buy two?

The manual RS4V has the extra tang with the bolt hole for the handbrake talk to the guys on the phone.

Call Joe Versace at Wheelworx for the fitment of your shiny new part. Be accommodating. Win.

Ah so is that what the extra bolt in the bearing assembly is for (saw that in the pic in the workshop manual)

thanks guys... from your descriptions it sounds like it is tyre noise. I only really noticed it after I had new tyres fitted (maxxis MA-V1's) and previously I had had the Z1's which were noisy. It it more of a high-med pitch whine/dull roar which starts at probably about 60km/h so I guess it sounds more like road noise (although could be diff - but doesn't change between accelerate/coast)

Only thing which confuses me a bit is that it gets gradually louder when braking, and continues down to fairly low speed (about 20km/h) when you pull up. Nothing very load, but noticeable, and from the back of the car.

Have a listen to the clip in a thread I started not long ago, and compare if it sounds the same.

I too have maxxis MA-V1 tyres and the comment about low speed noise rings true. If you listen to the clip you'll notice a low frequency roar as I brake and come to a stop. My tyres are about 4-5 years old.

Thanks for the details Springsteen, feeling a little better about doing a short cruise up to Sydney soon :-) No play in the wheel bearings that I can tell.

That's great stuff John - I think mine sounds very similar; if anything yours is pretty quiet... but yeah same sort of dull roar when coming to a stop, I used to have bad road noise with the Max is MA-Z1s, seems with these Max is V1s it's similar.

Hahaha, what a coincidence - you just happen to have fitted the same/similar tyres!

Yeah I thought that was rather interesting. I do remember the Z1's being LOUD! So I have put the V1's down as being "moderately loud... a bit like a wheel bearing but at a slightly higher speed".

    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
