Hi,

I totally forgot to ask.. i just picked up the car and left (because it was under warranty). I havent heard the noise since which is great...

I assumed it was in the diff as that is what the mechanic said to me initially.

I'm so so sorry...(trust me i've been kicking myself).

Hi,

I ended taking my car back to the main toyota service centre. I took one of the techs on a drive and pointed it out for him. He responded with "it sounds like a diff whine" before i even elaborated on how i took the car to another mechanic and that the 2nd mechanic favoured a diff prob...

He said he'll order in a few components for the diff so we'll see.

The diff is the differentials on your car....

We've managed to ask the actual mechanic about what he done and basically it was nothing.. he drove it, heard the noise and said that was normal... did not even put it on the hoist.

he suggested we take it to their main toyota service shop so the guys there can check it out further.. will be doing that next week.

will keep you updated.

hi,

I've got exactly the same thing happening with my 07 Auto Corolla (current shape). I get the noise when i hit between 50-60km/h and if i sit on that speed, it whines. However, if i go above and sit on 80km/h i get no noise. However, when i hit 100km/h and sit on that, then the whine happens again.

It only happens when my foot is on the pedal, the minute i take my foot off to slow down, no noise - the second i tap the accelarator pedal, it whines.

I've taken it to Toyota for a check and the mechanic there said that there is nothing wrong and that noise is normal. He reckons that the head guy in Toyota says that the noise is normal and nothing needs to be done. I've asked for a letter from this bloke in Toyota HQ indicating that this noise is normal and will not result in g/box failure in the future (from this noise of course). I'm yet to receive it.

I dont believe them cause i reckon its a bigger than normal job and they dont want to do it - the mechanic didnt seem helpful, just basically stayed away so he wouldnt get asked questions. My brother had sh*t fight with subaru when his impreza had a bad g/box. it took 6mths for them to finally do it after the Subaru Head tech in Subaru HQ intervened. The local subaru mechanic and the local subaru service manager had given my brother two different stories on what had caused the problem - and the service manager was a real ***** about it too.

I've taken the car to another mechanic for 2nd opinion and the he reckons it is the diff. This mechanic put the car on a hoist and put a stethiscope onto the g/box and diff and listened to both while the car was in drive. He reckons that the noise was much louder in the diff than in the g/box.

Anyhow, if you have had any updates on your issue, can you please let me know as i'm desperate to find out what i can do... this noise is annoying as it does it at 60km/h (your normal local street speed limit) and 100km/h (your highway speed limit).

thanks.
