Hi guys, just bouncing this off anyone that might know

when driving car for a few miles, I get a whining noise that goes in sync with wheel speed not engine speed, Ive been told its not a wheel bearing from a guy who did my clutch last week, but then he had it from cold so to speak, any ideas chaps?

Car is a Uk Impreza 2000 turbo 1999

Hi Mate
Had the same thing..... If it sounds like its coming out of the radio (general area) theres a good chance its the bearings on the center diff assy at the back of the box. If you get whats known as transmission wind up (ie after a longish journey when you turn into a parking space or thight turn the car seems to struggle to move thats wind up) you will need to replace the center diff assy as well as the 2 bearings that go into the rear casing of the box.
First the good news - the gearbox does'nt need removing to do this it can all be done in situe You have to remove the rear prop , gear linkage and gearbox mounts then the back of the box can be removed by undoing the ring of bolts around it.
The bad news - Its going to cost about £600 - £650 in bits depending on what oil you use.. You will need the center diff assy (which comes with a bearing) the 2 bearings in the rear casing ( if poss strip and check these bearings first as only one of mine had gone) the gearbox casing gasket ( this must be replaced because this helps set the preload for the bearings ect) and 4.5 - 5 litres of 75W90 synthetic gearbox / diff oil.
It would have taken me about 2 hours to do mine if Sparshatts hadn't supplied the wrong bearings and gasket to start with. This was with air tools and a lift but I had never done one before but did have plenty of advise (Simon @ Merdon motors 01489877431 ex top tech with Subaru) . No special tools are reqd just a press to change the bearings on the shafts.

You need the whole car lifted to be able to run it in gear for someone to listen at each corner and at the rear of the box if you suspect as per the post above.

I have a similar noise, again coming from the stereo are, but I've put it down to a failing power steering pump, only makes whirring noise when slowing down strangely!!
