shootin' the shit / Re: Cars, Cars, Fucking CARS !!
« Last post by spidermonkey09 on Today at 10:02:03 am »My Subaru Legacy has developed a very loud jet engine type noise. It drives completely fine but above about 30mph a whine develops which gets louder and louder the faster you go. It is worst around 60mph and then dies off a bit about 70. Its just about ignorable when driving but apparently for rear passengers its fairly deafening. Internet research/asking knowledgeable friends suggests this is likely to be either the rear diff or wheel bearings. The latter seem particularly bad on Subarus, but there is no discernable change in the pitch of the noise when I change lanes/ go round corners. However I'm not sure whether this would be as noticeable in the rear bearings as the front. There is also no change in the pitch/volume when I shift into neutral. As I brake the noise decreases.
Obviously I would prefer it to be the bearings as the expense of replacing a diff is likely to be more than the car is worth. Anyone got any suggested methods of diagnosis that I can do without getting the car on a lift? Is it worth taking a punt on it being the bearings and getting them done? Will changing the diff oil make any difference to the noise?
Currently my plan is just to drive it til something breaks and ignore the noise but I feel like it might be worth the gamble of spending a bit more money on it as its only done 110k miles and has hopefully been reasonably looked after as it has a full service history. All input appreciated!
