Wheel Bearing Sound Travel

Hey Guys,

I've searched the forums and found some info on the wheel bearings for M35 Stageas. The DIY bearing change was great and elucidated the procedure, but we can't seem to figure out which bearing needs changing.

Above 40km/h you can hear the hum start to wind up and the pitch goes up as the car's speed increases.

When you turn right and load up the left side (above 40km/h) the hum gets louder and more groan like. It sounds like its coming from the front of the car.

So, I go the part 40210-AL800 (from DIY thread) and got the local mechanic to change it (3hrs labour x $90/hr).

The noise is still there.

My question is: Is it possible for the rear wheel bearing hum to sound like its coming from the front on these cars?

Mine is a 2002 Autech Axis. You can see it was driven in a snowy area in Japan because there was a bit of salt on the rear end and some corrosion on the muffler. Other than that the car looks brand new and has 45k on the clock.

Other troubleshooting:

- Tried the spare on each corner to see if it was tyre noise (no change)

- Jacked up each side and tested for play in the bearing and spun for any noise (none)

Thanks a lot guys

Just want to clear something up here..

You supplied the mechanic with the wheel bearing?

If not guarenteed he didn't change it for $270 including parts considering the bearing is around $250 alone

Bearing can be purchased for just over $100 on eBay from the US.

I read the post as the LABOUR component of the task was $90 p/h, no mention of bearing in the price.

Change the other one. You may have misdiagnosed.

They've both done the same number of kays, if one is stuffed, the other on the way.

Yes I got the bearing from Steve Jarvin Nissan and supplied it to the mechanic. So you think it could be the other front one? I don't understand how the front driver side could be bad if it is noisy when I turn right?

Thanks for the help guys.

So should I change the front driver side bearing instead of the rear passenger one?

Sometimes I get a shudder like this one when I bump the synchro button:

I cant work out if I Have a bearing problem, at the front left, or if my tyres are causing the noise.

It sounds like a low rumble increasing with speed.

No play in the wheels and turning left and right quickly at low speed doesnt seem to generate any significant noise or anything unusual. There is a slightly more rumble noise on the turning component of the tyres as they turn.

i jacked up car and tried to move the wheels sideways but they seem pretty solid. No lateral movement.

If I move the tyres backwards then forwards there is a slight clunk.

Just roting the wheels they seem almost quiet.( it is not noiseless)

Can I ask what tyres you are running . I am running 225 45 18 dunop venturo at 41 psi

PSI is a bit high but from all repeort s this level gives better handling.

What tyres are you running?

What does your noise sound like ( any addtional details)

Same tyres as you Samuri. Mine doesn't make any noise until 35km/h then a low hum increases with pitch and volume as speed increases. Same here, no rotational noise and no play. Going to take it somewhere and put it on the hoist.

I definitely have a bearings

problem at the very minimum.

Making the turn right actually increases the sound on the left front bearing,

because of the additional load , putting pressure on the left front

bearing.

must the unit be replaced or can a specialist bearing

compAny fix it? What's the best solution and why?

confirming part number is 40210 Al 800

My front passenger side was changed by the local mechanic who has a press. Ordered the part from Nissan.

What I would really like to know is why do they go in the first place? How many kms on your m35?

Just for interest sake what did they charge you? I just done it myself and wondering what I saved.

270 for 3hours labour for one side. Is it design fault why they don't last long or could it be that they are used in snowy/salty areas in Japan?

Changing wheels/alloys to a non standard offset can also change the load characteristics placed on the OEM bearing and assist in their premature failure.

Unless you have original log books for the car, i wouldn't place a great deal of faith in the KM's on the ODO either so this might not be the best indicator to go by.

Mine have done over 100,000km, I think that's a pretty decent life for a bearing that takes the kind of load they are subjected to.

Not really a design fault, peoples expectations of mechanical component life expectancy is the issue here.

Agreed any car would probably need one at around 100k. Add to that our cars are high powered nd heavy all wheel drive cars pretty sure it is going to put a lot more wear them a general car

Before you go spending heaps on wheel bearings, i would put it on stands or a 2 post hoist and run it up in gear, use a screwdriver or stethescope on hte hub to determine what is the problem. I seriously doubt a wheel bearing has gone at 45,000km, even 100,000 is fairly unusual, but not unheard of

+3hours to press one in is a bit steep. Should be able to comfortably do it in 1.5

While i agree with you in theory on the time it "should" take, these can be a pain in the ass when they're rusted in and eventually need to be be cut/ground from the hub.

3 hours is about right if they want to stubborn.

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

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

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
