Whirring Noise While Driving - Wheel Bearings?

Recently I've had my M35 in at Nissan for a service and I mentioned that I thought the front wheel bearings may need replacing. I thought just the front right needed doing but Nissan told me that both front ones would need replacing. At $260 a side plus fitting, they're not cheap - so I want to be as sure as possible before getting these fixed.

Basically the noise has been getting slowly worse over the last few months - and is now audible at all speeds unless there is significant wind noise or something. It sounds basically like excessive road noise but gets sort of higher pitched the faster I go and is quite low pitched when driving slowly. The pitch goes up/down with vehicle speed, and is unrelated to revs or throttle. ie. Putting it in neutral and letting it roll makes no difference, and also there is no difference when coasting or under heavy throttle or even braking - it seems to only be related to how fast the car is moving.

However a couple of people have told me that it wouldn't be wheel bearings since the car has only done 92000km. I just cant think of anything else it would be.

If you've had your wheel bearings replaced, what did it sound like? Is it unusual for them to need replacing as low as 92000km?

Just dont wanna spend ~$600 getting them fixed if its not the problem...

Yep.

Had my front passenger bearing assembly replaced at about 86,000k.

Sounded much like what you are describing here... Very embarrassing in pear hour traffic!

Took it in to Nissan (Ferntree Gully) and Christmas time, they diagnosed it straight away and ordered the part from Japan.

10 days (not business days) later it was installed.

They had to make "a special tool" to get it on as it is "different" to any Aus delivered cars (what a surprise!).

btw, the front wheel bearing assembly was $211 delivered from Japan.

I was mistakingly quoted this as the install price, which they honored.

Well I finally got to the bottom of the whirring noise problem.

Turns out it IS actually just tyre noise, but the reason its louder than normal is becuase the tyres are wearing in such a way that its leaving a lot of sharp edges of rubber, particularly on the inside edge of the tyre. First I had the front passenger wheel off and had the space saver tyre on, and there wasn't much change, but then I switched the front right tyre with the space saver and it was a lot quieter. Both right and left tyres are wearing in a similar way - but the direction of the tread means that the sharp edges are creating a "lip" that faces the front of the car on the top of the tyre - kind of like this /| /| /| all the way round the tyre. Both tyres contribute to the noise, but its mostly the right tyre.

What it essentially means is that my wheel bearings are fine (phew) and that I can either put up with the noise, or just pay for new tyres. I'll probably just be putting up with it for now. We swapped the rear & front tyres (leaving each tyre on the same side as it was on) and this has made a small but noticeable improvement, and will even out the wear as well.

For anyone interested, the tyres I have are Firenza's (www.sumotire.com). Wont be getting those again.

I've notice I have a dull 'bonk' noise coming from the front of my car over general bumps as well as soft 'creeking' noise from the steering rack when rotating the wheel at low speed (parking etc). Had the guy doing my exhaust have a look at the bushings and ball joints, can't pick anything. Possible shocks need replacing? There is a lot under these things so I may take it to a suspension shop to see if they can run a test on one of those machines that emulate road conditions.

What areas of the M35 fail in the front suspension so I can have a nose around when still up on the hoist tomorrow?

Cheers,

Rhys

wheel alignment time? hopefully it was done when you purchased new tyres.

I honestly have no idea what was done - tyres were new from compliance. they would have to have done an alignment then but i have no paperwork other than an invoice. finding out anything else required specifically asking about each thing and the compliance place really didn't like me calling for stuff like that.

Still, I'm pretty sure it had an alignment done at compliance...I think its just maybe gone a little out of whack since. Will get another one done when I get the chance.

my guess they didnt do it. compliance places (no offence to any on here) will do things as cheaply as possible. its called business.

maybe get it done again, $60 for a 4 wheel alignment is cheaper than a few tyres

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      R32 GTS (RB20DE) Injectors Replacement

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
