Transmission Whine Options

[HardHead93]

Within the last few days I started getting a whine from the car whenever I push the clutch in but it goes away as soon as the clutch is fully engaged or fully disenaged. It even happens if I ride the clutch without fully disengaging it (no, I do not ride my clutch normally). Everything is pointing to the throw out bearing. mad.gif CRAP! I just got the car all back together and now this. The sad thing is that this is a fairly new throwout bearing that came with my SPEC stage 2 clutch. If I had to guess, there is less than 2000 miles on this throwout bearing. Is the throwout bearing going bad or is it just going to make that noise because it is not an OEM part?

If it's not the above it could be gearbox bearings, either diff or shaft bearings. Which LSD did you install too btw?

After the install of my TRD LSD I had a whine - which I thought was the normal mechanical clutch plate noise, after a couple of months it turned out to be a bearing failure. Luckily the work was done by Toyota, and I could show I purchased the Toyota parts from Toyota New Zealand, so I was covered by warranty, I now have a unlimited lifetime warranty on the gearbox.

I know it is not the gearbox because I had a tranny shop I trust inspect the S54 before they put the LSD in and they said everything was in great working order. There was hardly any metal on the magnet inside the tranny plus there is only 130K'ish original un-boosted miles on this tranny and I have seen these trannies go for close to 300K miles if they are taken care of. I am a realist and I know I probably won't get that much out of this tranny because of the extra stress I am putting on it with my 3sgte. As far as LSD, I have a Helical Limited Slip Diff from an MR2. I got it used. It makes sense what Box said about the throw out bearing so I will start there. If the whine does not got away with me replacing the throw out bearing and greasing it properly then you may be right.
