I might just be being a bit over the top as I always think I hear things driving my scoob but I've got a feeling there might be a very slight whine that has appeared on deceleration and down shifts.on deceleration its more in 2nd I think.could it just be that it needs new gearbox oil?i have been thinking of getting that and the diff oil done soon anyway.
Oh yeah nearly forgot the most important bit,whoops!!!its a Sti on a 53 plate so 6speed box but not DCCD.
Cheers Michael

 

Diff' scan whine when backlash not set properly between crown and pinion might be that?

Or preload not set right in the bearings

 

Could it be this even if its only just started having owned the car 3 months?

 

Most cars I have ever owned(And ive owned a lot) have had the odd whine hear or there if you listen for it.

Stop worrying! like most people on here do far to much!

One day you will have something to really worry about, and I bet this aint it!
