I did a search but didnt come up with anything? Sometimes, when I am making a left turn, there is a grinding noise coming from my rear axel (sounds like rear left)... i am going to ask the dealer, but wanted to see if anyone had the same issue

 

have you had your car towed ever? any suspension mods?

 

i got this car used but never towed that i know of and no suspension mods

 

I've got a noise similar to that. More of a whirling mechanical noise that a grind. Only seems to happen on sharp left turns.

I thought it was something do to with the differential and tires. I've put 30k miles on it and nothing has broken yet...

 

I've noticed similar noises. Bought the car new, never towed, no mods. Haven't noticed anything other issues. Just the noise.

 

Sure it isnt the differential or wheel bearings?

 

I have a similar issue. It happens when I slowly turn my car right, this is like when turning into a parking spot, garage etc.

I did take it in to get it checked and the service manager said that it was the bolts on the subframe that weren't torqued right. So they did what they had to do. But I can hear the noise again, so I am gonna take it in again and see what gives.

 

I just posted in the tech garage that the limited slip clutch plates in my diff just failed. Mazda is going to replace the whole thing. I'm still waiting for the part after 11 days.

This could be your problem, especially if it gets worse over time and occurs under additional conditions. I'd get it checked but be skeptical of the dealer response.

 

I hear the exact same thing. Almost like the sounds of wheel bearings going bad. I thought it was the brakes but Smithtown Mazda changed the pads and rotors and the noise still continues.

I'm going to take it back in for them to look at since the car only has 11K miles and is an 05. Hopefully they can figure it out.

It sounds like a grinding and is noiser when coming to a stop.

The LSD engagement does make a little noise and you can feel the action if you're in tune with such things. Hopefully that's all you're experiencing.

I had a similar noise develop at about 40k mi. At first I thought it was tire rumble from the OEM Potenzas, but when I got new tires and the noise persisted I went to the dealer.

Bad wheel bearing - replaced under warranty.

 

I had my diff replaced because of this. Happened only after long drives(hard to duplicate for the dealer). Turnning off the Traction control or Dis did'nt make any dfferences. I had it posted in issues and problems "Rear end Shudders"
Goood Luck!

 

Was it the front or back wheel bearings?

thanks,

anthony

 

I bought mine new as well (currently 13k miles, never towed, no mods, etc.) and I think I may possibly have heard a noise similar to what ur refering to. I've heard it from the time I got the car, and it happens whenever I'm making a turn in any direction sufficiently hard enough to swing the rear end, but I've always attributed it to the traction control engaging to brake the outside rear wheel. Maybe that wasn't an accurate assessment on my part, but that was my initial diagnosis.

Having read this thread, however, I may need to have my 8 looked at... First, I'll probably experiment with and without the traction control on to see if that's actually the issue. Hopefully, it's nothin major

 

sounds like a problem i had many months ago. a grinding sound from the rear in low gears, especially when turning. it got increasingly worse very quickly until the entire car started shuddering fairly violently. turns out i had the wrong viscosity differential fluid (pep boys, etc...wasnt during my ownership). after that was drained and properly cleaned out, replaced with the right fluid, the grinding is totally gone. get it checked out.

 

Right-Rear wheel bearing was replaced.

 

Just had a long 2 hour drive and guess what...exact same thing! I tried with and without the DSC or TC, and it happens if I turn left or right. I caught it before after arriving home, but it was not as obvious.

Only 20000 miles, I already had a tranny switch, now this???

 

Mine has that noise since day one. I always thought that it was normal....

 

Hi Guys, I'm glad to see that i'm not the only one who is having this problem. Mine happens from time to time. Especially after longer drives. Doesn't happen every day but, happens enough to annoy the shyt out of me. I also had this same problem in my 94 Touring FD. Surprisingly I changed the rear diff fluid and it never happened again. I think I am going to do the same with this and see what the outcome is. I also want to take it to the deal since it is still under warranty. It is an 05 model year. . Don't think the rear diff fluid has ever been changed with some cheap stuff, but nonetheless, it probably never hurts to have new synthetic rear diff fluid in it.

Thanks

I've got the same issue. Mine happens more after long drives and only on hot days. I took it to dealer a few months ago but it wouldn't do it for them (wasn't hot enough). Never happens when it's cool outside or the car is cool. I bought it new and it's been doing it since the first summer I had it. Have not noticed it getting any worse.

 

it seems as if it only happens when the car is warm/hot. anyone can clarify what causes the grinding sound? i am having the same issue but couldn't replicate it for MM

 

Couldn't replicate it today at my service visit...SOL.

 

are you sure? I heard it too, mine doesn't come with DSC or TSC for that matter, anyhow it only happens when I drift or mad left turn burnout, my friend's car has it too but he said that was from his LSD, from what I've heard the rx8 already comes with a 1.5way LSD? maybe you're hearing that

 

I only get a wierd sound going in reverse when turning out of my driveway... i figure its normal.

 

Change the rear differential fluid. When you see the sewage that comes out of the drain hole, you'll understand why your rear-end is groaning in the corner. There are millions of threads on this issue in the tech forum.
