Thrust Bearing noise
Hey guys had the car two weeks and Ive noticed quite a loud thrust bearing noise its very noticeable from outside and in the cabin
whats the norm?
any noise at all or do they moan ?
Im going back to the dealer and I just want some advice if I should push the issue to change it or not ?

Probably normal. By the way, it isn't the throwout bearing, it is the transmission input shaft that you are hearing. You'd hear the throwout bearing only when the clutch is depressed, because that's the only time that the bearing is in use. When the clutch is released, the throwout bearing shouldn't be touching the clutch diaphram, and thus not making any noise.
The input shaft does make a little noise. - all of the Mazda's I've had were similar.

would you consider the absence of cylinders normal?
no, it's just different, it's the way it is. i dont understand why everyone is up in arms about the noise.

Well probably right but I can hear it while I drive only the radio
kills it . The loan car I had had more K's on it and it wasnt on that one and I test drove a car with 10k and it wasnt noticeable there
either.
But It could be me as you get used to a car you start to hear all the little noises so I'll ask the newbie question from the dealer and see what I get
:D

But, as someone posted...I'll get used to it eventually, or I'll get rid of the car.

mine's not nearly that loud, so mayube you should get it checked out.
but also, have you owned other rotary manuals? you might be mistaking sounds from the motor as coming from the tranny. since our motor are halfway in the tranny tunnel anyway!

If you have to open the windows on the highway in order not to hear the noise, you have a problem. I'm an ex-rocker and have very sensitive hearing. I can't handle loud cars (or other loud things) any more. I find the RX-8 to be a pretty quiet car. Not as quiet as an IS300, but definitely quiet for a sports car. No drone, highway road noise quiet good considering the 18" tires. I can do 10 hours driving per day in it and I am not hearing- or other wise fatigued at the end of the day.
What I do hear a little of is the transmission turning in neutral while the car is idling. It's barely audible if the windows are up. And, even with the windows down, it's not intrusive.

Same here, the only noise that I come across is the input shaft when I release the clutch at idle.
I showed this to my dealer, he told me that every 8 he has worked on has that noise.
I do get a little bit of gear whine around 2-4 but I reckon that is normal, (it was on my old nissan stanza)

You should not hear any noise when it is in neutral and then goes away when you put in the clutch, My RX8 does that when I first drove it, I made sure I informed the sales manager. I had a 2000 Celica GTS that did the same thing and it was FIXED!. THe Celica was new and had problems too that were also fixed,
From what I gather......the Mazdawg has some problems that may or may not go away or be fixed. I have heard nothing about an 05 RX8 so I am guessing maybe they will drop the car after one year.
I mention RX8 and the sales people cringe and cannot hide it......I am thinking of trading it for a WRX and I only have 300 miles on my RX8.
And to think I traded my 1995 Toyota Supra NA for this.....that Supra was Bullet Proof! but I had 120k miles on it and thought it was time .......it was an automaic and it wasn't a Turbo anyway.
Now I think I should have got the WRX instead, we have a STI WRX but I thought maybe get a standard 5 speed WRX.
I have owned two Mazdawgs before, a protege' and a MX6-GT (Turbo) which both were incredibly awesome and reliable cars! more reliable than the three Toyota Camrys I owned.
If I come upon the Lemon Law threshold, then this time I will enforce it and make them Buy it Back from me and then I will go and pay cash for the WRX since my RX8 is paid in full!

Sure... they'll drop the 8... <rolls eyes> and just scuttle all that cash that went into engineering and producing a new platform.
Pilot bearing noise is irritating, but it's VERY widespread, and when you have to replace the clutch someday, make sure you replace all the bearings and you'll be fine. PB noise does not make a lemon.

There's plenty of threads here on this forum that have discussed the very minor changes due for the 2005 model year. For your information, the RX-8 is meeting Mazda's (aggressive) sales targets to date - in other words, it's selling very well. It's not going to be dropped, that's an incredibly stupid thing to suggest.
I don't know what your problems are with your car, but you don't need to be ignorant about it!

Gordon

gee I disctinctly remember posting a reply, and Voila! it's gone!
this Noise is not good, it is not acceptable nor do we lower our standards to tolerate it. this board is most likely moderated or supported by Mazda hence the deletion of my previous posting, they made a defective product they need to fix it! I am guessing even with 300 miles on my RX8 I am trading it for a better car a WRX

Did you read the thread linked by Snap-On? It's transmission gear roll-over noise, and it's common in many RWD transmissions in an assortment of different vehicles. It's not a defect, it's not a problem. If you can't stand it, then you are most welcome to take a huge loss on your car and buy something more to your liking.

No I did not violate any rules with my post that disappeared.
However I am a former Automotive Engineer and that is total BS about gear noise whizzing in neatrual???
WTF?? the only mechanical connection between the engine and transmission is the clutch and pressure plate and of course you have a pilot bearing and trhow out bearing either or......they make noise when there is a problem, stop trying to fool yourself or kid yourself, this is a major vehicle issue because it is so widespread...
meaning there is so much of it we are resigned into being manipulated into believing that it is something that we have to live with and accept!
BS!! It is not,
I had a toyota celica that did that and it was FIXED! Mazda is going to have to NUT IT UP and take responsibility for a cheap defective part and replace it at no cost,
like I said you have a problem car, and it gets to the LEMON LAW threshold, they buy it back, I get a WRX!

OK, back to class for you - please study this manual transmission simplified page from www.howstuffworks.com .
Yes, the mechanical connection between the engine and transmission is the clutch, pressure plate, throwout bearing. Is the throwout bearing doing anything when the clutch is not depressed? NO. Can the throwout bearing be the source of the noise, then, when the engine is idling, clutch engaged, transmission in neutral? NO. So what is happening when the engine is running, transmission in neutral? The transmission input shaft and layshaft are turning, and there are gears engaged between these two shafts. Note - gears are turning, shafts are spinning - so much for your statement about the mechanical connection between the engine and transmission - that's completely irrelevant, since the transmission is the source of the noise, NOT the connection from the transmission to the engine.
Back to gears engaged, shafts turning. Since the transmission is not under load, the gears can cycle rapidly between having the front faces of the gear teeth in contact and the back faces of the gear teeth in contact. That cycling of contact/pressure points on the gears is what makes the noise while the transmission shafts are turning over in neutral.
Thems the facts, whether you understand them or not.

Gordon

Well Kiss my *ss!!!
I am a former because it paid ****!, what I do now pays more than twice as much!
how things work, hahahaha yeah my kids use that site when they were in elementary school.
Have you ever changed a clutch??? what? you know a clutch??
BTW it's not a good sign to hear any noise however you want to rationalize it or however you want to minimize it, that's it keep telling yourself it's OK.....
the boogey man transmission noise monster really isn't hiding under your bed!!
