Got a couple of problems:

whirring noise from rear increasing with speed, diff oil is good, wonder if the centre prop bearing / support could be the culprit 

leaning out / hesitant under medium throttle. Suspected a worn throttle position sensor then it self healed 🤔 came back today and worse. Not really responding properly in medium / heavy throttle below 3200rpm.

the car has covered 77k with a good history file. I bought it in December.

given the mileage, I’m wondering if there are known common issues to point me in the right direction

 

 

 

 

Whirring noise in rear more likely wheel bearing given age and mileage.

Doesn’t increase with corner loading. Near side rear one got done on warranty 

wheel bearing.

 

mine's doing the same it's doing my head i. hardly hear it at 30mph.. 50+ 70mph.. it's a case of turning the radio on! lol

Had it on the ramps on friday and it's looking to be OSR 

 

got it booked into Subaru Nottm for this coming Friday... about £180

It’s starting to develop into nsr under load. Think you’re right. Failed bearing / installation . Main dealer fitted too.

That's where you went wrong main dealer. They are useless in my experience. I good indie that know Scoobies would do you better.

Rough running. If it was my Hawkeye I would check MAF sensor and plugs. Not sure about forester
