Rear Diff question...
Posted 26 April 2007 - 02:03 AM
Should the rear diff be this hot?
Has anyone encountered this type of 'fluttering' feeling throughout their vehicle?

there are a number of options but my first guess is a ujoint in the driveshaft. check the ujoints for any play. if it's very light and "flutter" like you said, you might not notice any problems unless it's removed or you have a really good eye for spotting seized ujoints. the joints could be seized instead of having play in it and in those case they are very hard to diagnose without actually dropping the driveshaft down.
before going through that you might want to make sure it's not a wheel out of balance or a bad/old tire as well.
i'm doubting it's your diff, but it's not impossible. they normally like to make noise, not just vibrations. there are a couple other things to check but i think they are less likely so im going to stop there.

I had the car up on ramp on Monday and did a thorough check of the driveshaft and it is solid from front to rear. I looked at the U-joints, but I don't think I would be able to tell if they had seized.
I have ruled out the problem as anything related to a tire/wheel due to there being no shake/vibration in the steering wheel.
It is quite hard to describe this 'fluttering' that I feel. It is like I am feeling it through my body, like super low bass on a good subwoofer. At first I was not even sure it was there, but after a period of 2 weeks I am very sure of it. I also thought it could have been my rear spoiler 'fluttering' in the wind. I checked it and it is solid and tight. It isn't a spoiler like on the newer Subarus, but an aluminum fin type that creates a downdraft over the rear window.
