The other members of the 'work club' have, I believe, open diffs front and rear: one '99 Forester S, two '99 OBW's, one '02 WRX. I am the only one with a rear LSD.
Steve
'00 Outback w/ AWP
'01-'03 Outback except VDC model
'01-'03 Legacy GT (maybe '00)
'00-'01 Imprezza RS (maybe '99)
'02-'03 WRX
'01-'02 Forester S (maybe '99 & '00 S)
'03 Forester XS
The following had a mechanical (clutch plate) rear LSD:
- some (maybe all) years of Legacy Turbo ('92-'94?)
- RX turbo and GL-10 Turbo (not sure what years but I know my '89 GL-10 Turbo had one).
- SVX??
DaveM
Have heard of not screwing the gas-cap in tight enough resulting in the check engine light comming on though. I also know the WRX has a rough idle compared to other cars.
Sure about the Legacy Turbo using a mechanical clutch-type?
-Colin
cheers,
Steve
SVX is viscous as colin said, as was the XT6 rear LSD (optional on the XT6) I'm pretty sure the legacy turbos were viscous but not positive.
-mike
The following US models have viscous rear LSD:
'00 Outback w/ AWP
'01-'03 Outback except VDC model
'00-'02 Legacy GT
'03 Legacy 2.5GT
'00-'01 Impreza 2.5RS
'02-'03 WRX
'00-'02 Forester S
'03 Forester XS
'92-'97 SVX
'91-'94 Legacy Turbo (Sport Sedan & Touring Wagon) - may be year, model or transmission specific.
'89 RX Turbo & GL-10 Turbo Full Time 4WD - 5 speed only - not sure if clutch type or viscous.
I think I got it right this time. At least I spelled Impreza correctly this time.
Mike - maybe this is another item for the FAQ site.

With the metallic - tinny rattle that I heard from my stereo that I posted earlier, I finally located it. It was not a blown speaker or bad reception, but the speaker cover for the subwoofer. Aparently, at certain frequencies and certain volumes, it vibrates. It does not happen all the time, just on occasion, and this is why. I was able to find a spot where a Styxs greatest hits plays where it rattles. Will be bringing it in when I get my clutch replaced.
Thank you for the suggestions and help though!
-Bob
Again, to preserve the mechanical integrity of that expensive center diff, & in some cases the rear diff (and not to mention the possible warranty expense to Subaru), you would think they would publicize this information better?

While I was there, I did some maintenance items. '02 OBW w/ 13.7k miles:
1) Checked brakes. Pads still look like new all around. No grooves in the rotors. I was going to pull the calipers and clean everything, but didn't have any high temp grease for the pins. And with more salt dumped on the roads, I think I will wait a few weeks, then do a thorough PM. I also thought about adjusting the parking brake mini shoes, but was not sure if I could really 'feel' the drag point or not. This was easy to do on my old Camry (FWD) as there was no mass attached to the rear hubs. I am a bit stumped with AWD as there is a lot of rotating mass there. The hand brake seems to work fine, so maybe I will leave it alone for now...
2) All boots (CV and steering) and ball joint covers look good. Noticed some dampness (maybe tranny fluid) on the inboard (green painted) half shaft on the passengers side. This is right above the exhaust, so might be one of the sources of the famous "Subaru Burning Smell"?
3) Exhaust shields are all tight, although the hardware already looks severely rusted. I foresee shield vibration noise in my future....
4) Carefully lubed all of the suspension linkages and bushings with spray lithium grease. Note to all - cover the brakes when you work with spray lubes!
5) Cleaned the wheels and waxed inside and out. Rotated the RE-92's (positions marked when I took them off last Fall), adj tire pressure.
6) Replaced the air filter last week. Checked hoses, belts, & fluid levels. Topped off the coolant (down just a fraction). Took off the winter wiper blades.
Now some questions:
1) In the past I used my floor jack at the side sill points, but this time I wanted to lift each end at once. I looked at my friends Forrester Shop Manual. In front I used the brace under the engine just ahead of the exhaust "Y". But I was confused about the back. Actually on the differential housing (wider rear portion - which I did), or on the cross brace towards the front of it???
2) My Dunlop snows are directional tires, so they have to stay on the same side, but the OEM Bridgestones are not. The owners manual specifically says rotate front to rear only - DO NOT switch sides. Any thoughts? Unless the tread pattern dictates, modern radial construction should not prevent cross-rotation. I went front to rear, but want to cross rotate to even tire wear in the future.
Steve
I read that bit in my '99 Impreza manual as well and rotated side-to-side when the tires permitted anyway.
No problems.
Not sure what that clause is in there for...
-Colin
Len
Nice write-up. Non-directional tires can most definetly be cross rotated on our vehicles.

First I had problems with belts shifting on two different tires, the place that supplied them then agreed to replace all 4 tires, well after several months two of the new set got flat spots.
At first they tried to claim that I had bent rims they tried God knows how many times to balance them, I just went in one day and flat through a fit and made them take all tires off and then check my rims for problems.
Needless to say there was nothing wrong with my rims, I them made them install Goodrich Radial TAs. these by the way were on a Toyota Corolla that I owned at the time.
BTW the continentals were sport contacts.
Cheers Pat.

Puzzled, I waited a second, restarted and this time the engine RPMs dipped back down to 1500RPM and sort of bounced around in a rough idle. I let it sit for a few minutes and everything seemed fine afterwards.
Strange.
Ken
Steve
since they just worked on the exhaust I might initially suspect an oxygen sensor problem if the behavior continues.
did you notice anything else? any driveability problems, noises or smells on the way to work?
-Colin
Mark: try parts@libertysubaru.com for the cheapest prices I've seen. Or sure, get crafty like Pat did. Check the photos section, IIRC, he shared pics.
-juice
We could pay him a visit with my new front bumper..

-mike
I suspect who it is, but no proof. It was at the park-n-ride in South Beach. I think it was a Chevy Suburban.
Mark
point it out, and mike might unsuspectingly "oops I should have reversed instead of drive forward". ;-)
-Dave
-mike
Is there an O2 sensor in the exhaust?
No, nothing strange after that intial startup issue. In fact, the Forester ran fine the few days immediately after the repair.
Ken
-juice
yeah there's one in the right hand header before the Y-pipe --certainly the area being worked on-- and also one after the catalytic converter. the first one is used for the fuel mapping, the second only for EPA regs (evaluating catalyst efficiency)

You may have to join imagestation to view the album but membership is free.
Cheers Pat.
Colin -- I didn't know that and it makes a lot of sense. If it persists, I'll be able to give the techs a start.
Ken
Anyway, I checked 1stsubaruparts.com for a grill and I think they were running around $100 (?) for a replacement...whatever the price was, it was more than I felt like shelling out at the moment and I didn't order it. The dealer quoted me something like $160 for the part.
Brian
but your problem could definitely be unrelated. very mysterious at this point, just one bad start.
-Colin
Len
I took a look at your homemade grill. Nice job- a little different from the original, yet not enough to be "off". Something to consider.
Brian- I did not receive any bumper damage (although my license plate was partially bent), but otherwise sounds similar to you. I'll check out 1stsubaruparts as well as liberty parts and see what the cost is. I wonder if I could use my Subaru bucks at Liberty towards the grill.
Mike/Dave - I have to admit the next day I was tempted to pull a "Brooklyn move" and leave the gentleman with a "low" tire or two, but then I thought it's not worth it, especially if I'm not sure if he is the correct person.
What a differnec from years ago when I visited Virgina Beach overnight. Somebody broke my drivers side mirror in the middle of the night while I was at the hotel. When I came out the next morning, the person left their insurance info and telephone number, along with an apology on my windshield. Live and learn. I now make sure I park head first facing another parked car, not a truck.

Good question, as the WRX has a rear LSD, but a fixed mechanical (no electric shut off) center diff. Putting the doughnut on the front saves the rear LSD from wear, but you cannot stop the center diff from fighting the 'front to rear' difference. Any thoughts??
Steve
-mike
The center viscous coupling should allow for small differences in rolling diameter. Think about a U-turn, compare the front outside tire to the rear inside tire, the outer tire probably travels twice as far.
Plus, the spare is limited to, what, 50 miles of driving?
-juice
-Dennis
Cheers Pat.

I've also driven over 100 miles with the FWD fuse in place just out of curiousity, so it's not a fragile system.
The manual models with the viscous center diff can handle it as well. In addition, the front and rear rotation differential would be half the side to side rotational differential due to the physics of the system.
I have no info on the VDC, but that would be interesting to hear. Anyone?
