Whine

[raddish]

Hi, I’ve got a 55 wrx wagon. Drives great. Nothing to worry about and i hope this is just me. I can only hear noise for a second, but at motorway speeds70mph and 2500 when you come off throttle, to slow down there’s a second where the car makes a whine, doesn’t seem to be engine, just off throttle for a second, then stops. Only time I hear it, not at lower speeds. Anything to be concerned ?

Had a 55 WRX saloon for 10 years, but didn't experience your problem...

It might not be anything, might be wheel bearing, just wondered if it’s normal, it’s been 10 years since I have owned a Impreza. It’s nice to be back. Few years back the wife’s xc70 has rear diff issues, it used to do it on deceleration, but this us completely different, a hum for a second after accelerator is lifted, that goes but isn’t speed related, ie pitch doesn’t change with speed. Just noticed it on exit of motorway.

Does it do it when you come off boost?

[raddish]

No, it’s only done it when I came off the motorway, any other time on low speed it didn’t do it, even a 2nd gear acceleration on duel carriage way it didn’t do it. It’s not done it anyother time time. It only did it first a second. Seemed more rear noise, but could don’t be sure

Seems to only do it 65-60 mph. A hum noise. There seems to be a fair amount of wind noise through windows and sunroof, so cant get a great idea on noise, it’s not there on acceleration/throttle.
