As I noted before, the Subaru's are noted for failing wheel bearings. Another possibility is one or both rear tires being "saw tooth" from the rear toe adjustment being off. Sounds just like a bad wheel bearing. Easy enough to check by eyeballing it, and running your gloved hand over the surf

I'm becoming convinced that I'll be replacing a wheel bearing in the future but not sure which one, yet. Based on my research, the wheel bearing assembly is a unit that is just bolted to the knuckle from the inside but it could be a tight fit. The job doesn't look hard if the bearing unit isn'

Merry Christmas to all. Thanks to Rick and Peter. I was not aware that this is a frequent problem in Outbacks. I especially appreciate Peter's technical discussion and insights. I think you may be right. I just returned from town with 18 cases of cat food in the back and it did sound louder

Having just finished replacing the third wheel bearing on the Golf, I'd guess a wheel bearing, especially if they are similar to the MB rear bearings. Since those are double race ball bearings, they don't make the same noise as tapered rollers when they go, they tend to hum, then growl, then how

From what you wrote, I posit the 60,000 mile service, which replaced to CV boots, was the starting point of the noise. It suggests to me that "something" was not bolted back on correctly, and that is the cause... Questions: Did the shop remove the axles to replace the boots? Were the axles repaire

I’m seeking wisdom from the group. My 2008 Outback has been making an odd humming noise ever since the 60,000 mile dealer service. The hum varies frequency with speed but does not seem to vary with light acceleration or coasting. Strong acceleration drowns out the hum. The hum isn’t loud and
