97 outback/ auto.212k mls noise from rearend when giving gas, let up or put in nuet. noise goes away. a mech said it was bad front differential, noise telescoping to rear thru d/shaft. i might drive 20 miles a wk. met/fileings in oil on dip/stk. do i need a new differential or could it be a bearing?

Sorry that I never responded to this..... I was out of action for a couple of months here! The mass airflow sensor is located after the air filter box in the intake hose. It should be on the passenger side of the vehicle, and you will see a large connector w/ wires hooked up to a black box. Just disconnect the connector, loosen the clamps that hold he box in there, and pull it out! The sensor element runs through the middle of the opening in the box.

It is really difficult to determine what you tried to say in your post. However, to what dipstick are you referring? The front differential? Change the oil and see how much metal is in there... you might need to replace it, but take it one step at a time. After all, at this point, it might be correctable (or at least delay-able).

the oil was changed in the differential and the metal filings were on the diff. dipstick, after new oil was put in. now the noise has increased. i thought about disconnecting drive shaft to see if noise changes or goes away that way. then i would know for sure if its in the front or back.

Disconnecting the driveshaft is a good way to isolate it, but if you are getting that much metal in the front differential, that is most likely the source. And, if it is shaving that rapidly, it probably will not last much longer.

Do the signal lights come on when you engage either switch? If so, the flasher has likely quit. If not, I am not sure....

Well, there's the problem. If I recall correctly, the front differential and the transmission/center differential share the same housing. Therefore, the unit must be replaced together or the front differential rebuilt. (The unit is referred to as a "transaxle.")
You could probably replace the unit with something from 95, 96, 97, or 98 without any problems. The '99 was changed slightly from previous units, but that year has (based on empirical evidence) some issues with transmission reliability, so you should probably stick to the earlier years.
New, I think these units are about $5,000, but used you could probably find one for between 500-1000, and rebuilt are probably somewhere in the middle, about $2500.
