Differential Noise

[Richard]

I have a 1999 Subaru Outback Sport with 107,000 miles and an automatic
transmission. Recently it appears that my rear differential is making a bit
more noise. It sounds like I have snow tires on the car which I don't. I
only notice it when I am going above about 50 miles an hour. There are no
engine warning lights. I was wondering if this is normal aging or something
I should be concerned about? Thanks

Could be the wheel bearings are getting noisy. This sounds a lot like
aggresive snow tires.
Does the noise change when you turn left or right?

I don't think so, but I will check it tomorrow when I have to go on the
highway.

Stupid question, but you didn't mention it in your initial post: Have you
checked the fluid level?

 

[Richard]

No, I have not checked the fluid levels. I just assumed when I took it to my
Subaru dealer that they would do it as a part of the regular service. I will
mentioned it specifically next time I take it in for service which will be
this month. I looked at the differential and did not see any oil leaks.

Before I drove too many more miles I would check this, or have it looked
at! If the level is low and the gears etc are not getting proper
lubrication the whole thing can seize. Not a good thing on the highway at
70MPH!!

I have this problem also, I have 1995 legacy wagon automatic awd, The
rear end can be damaged by having one tire larger or with higher tire
pressure than the one on the opposite side of the car.

I have an appointment on Thursday to have my Subaru dealer look at it. I
will report back with their findings.

The dealer said it was a bad left wheel bearing which he replaced and the
problem is solved. Last year I had the right front bearing go bad.
