I actually have a few of these on my fridge! I have had the front offside wheel bearing changed as that was failing. The noise is still present. My local garage is skeptical about it being a rear diff grumble as they have had it on a road roller and driven it themselves. Unfortunately I don't think the roller can be conclusive as it is not under 'load.' Anyway, the rear tyres are wearing (also they do not match the fronts, so I am having them replaced as well, as another process of elimination. I hope this process does not end up costing too much! |

Certainly didn't feel like that. Checked the wheels for extra warmth and always cold to touch.

I am now but can't be certain of proximity to the sea before I purchased the car.

This is what it sounds like with chassis ears fitted, unfortunately mine now sounds the same!

Interesting and informative. I would like to hear the diff after a repair now to see how silent it was. FL2 MY10 TD4 GS traded in at 2 years

Me too YB, I bought the earlier none wifi version because a set came up on gumtree at a sensible price.

Alex, my GG AT2 tyres have the same issues. Whining/withering sound at 30 then 60 then again at just over 70mph. This started the first time I fiited them as winter wheels. Very much depends on road surface. It can dissapear on stonechip covered tarmac and generaly the newer and smoother the road is the worse it gets.

When the rear differential bearing failed on out FL2 , indeed one day it was not noticeable and the next day it was not noticeable .Of course the damage had not occurred in a short time , it was the result of 40,000 miles of wear on a badly specified component . There was a variation of the noise , under a heavier load , like acceleration , the “ grumble” was louder and on constant throttle at cruising speed the grumble was lower but constant . At no point if you listened carefully did the noise go away . Our GS auto is on Scorpion ATR and they are a very quiet tyre , and on a good surface the car is very smooth and quiet , so the day the bearing “grumble” started was obvious . I went through the usual, is it tyres? , is it a wheel bearing ? However after using the car on a 400 mike drive it was obvious that the problem was getting worse and was indeed the diff. 2009 GS Auto Zermatt Silver - Sold June 21 after 10 years of ownership 2016 Subaru Outback SE 2.0 diesel SE Premium Lineartronic Sold 2024 after 8 years and 80k miles .

After some more road experiences - where the sound changed intensity based on sudden changes of steering direction - and a careful inspection - I've had access to an elevator - I've concluded that the sound comes from the rear right wheel bearing.

Not that unusual for a wheel bearing to fail like that Alex, plus you often get accustomed to the sound as it develops.
