Well tonight I got my wife's Outback up on my neighbor's lift. Installed the Transfer Clutch Seal. 2 1/2 hours, start to finish. Filled up DEX III, warmed up everything, and put the front bumper against a big tree. All 4 wheels spun! A $1.48 seal kept 4WD from working. Thanks to all who helped me resolve this! I checked the dealer's receipt from when I had the Clutch pack and Duty C replaced, and they never listed the Transfer Clutch Seal in the new parts list. Should I complain to the dealer that they had broke the 4WD, and what it took for me to fix it?

Hey Dave, Thanks for the picture! Yep, that little bugger was missing from the Duty C that the dealer had installed. And when I replaced the Duty C to see if the dealer had installed a defective one , I did not know about that seal, so I never installed one, either! Not 5 minutes ago, UPS dropped off a small package containing two seals. Heck, they are only $1.48 each, so I got 2 of them, just in case I screwed one up. I am scheduled to get the Outback on my neighbor's lift on Saturday. I'll post if that fixes the issue. I'm sure it will!

I think I posted the wrong position for the Seal, in the above thread. Heres a new pic of where I believe the seal should go. The Service guide doesn't even mention it, in the "Remove/Replace Duty C Solenoid" Section. It must be mentioned elsewhere, but I haven't found it. Seal on order.

Could this be the missing rubber washer?????

Here is a pic of the valve and where it should contact the Extension Case. It sure looks like there should be a gasket there!!! But when I removed the Extension case after the dealer had replaced the Duty C and the clutch pack, there was not a gasket there. I cannot find a P/N for one. I'll keep checking...

Please elaborate. The Valve is not mounted to the tailhousing. I just double checked the parts diagram and I do not see where there should be a rubber gasket, except under the two mounting bolts for the valve. Do you have a diagram of that rubber washer? Thanks.

Heres a close-up picture of the new clutch pack that the dealer installed. I count .... 5 plates? Also, heres the pic of the Duty-C. This is the one the dealer installed. The replacement Duty-C I bought was exact same P/N and looked exactly the same. Also, a pic of the old Reduction shaft alongside the new reduction shaft I put in.

Nope, driveshaft was bolted in place. I had to remove it when I pulled the Extension case, then I reinstalled it. Good question though. Also, when I spin the driveshaft with my hands, the diff, axles and rear wheels do spin correctly, so that rules out a blown diff.

Yes, I knew about the changes to the Duty C during that time frame. So I double-checked what the dealer put in, and I thought it was correct. Duty C installed by dealer was P/N 31942AA130 (valve AY-TRF CCH). I ordered the same P/N when I replaced it. If it was the wrong Duty C, I think the rear clutch pack would be "Locked" if the FWD fuse was in place. But with the FWD fuse in place, it still didn't have Rear wheel drive. The Subaru Tech guy I spoke with about the code, said it wasn't the speed sensor, but more likely the Reduction Shaft. Since the rear Speed sensor is hardwired onto the Trans Wiring Harness, I took it upon myself to replace the Trans Wiring Harness, with all sensors. Yep, that didn't fix it either...

Hey guys.... first post, here. My wife's 2004 Outback 2.5 4EAT was experiencing the infamous rear wheel Binding while slowly turning into a parking spot. I knew it would be a rear clutch pack and Duty C solenoid. I had the dealer do the work, since we needed it done in 3 days. We were moving. SO, the dealer got the work done for a little over $1000.00. Ok, we drive to our new house several states away. Hmmmmm... funny, when I hit the gas, the front tires are spinning on the new gravel driveway! What? No Rear wheel drive anymore!! AT Light not lit. FWD fuse not in. DEX III filled and double checked. Well, I'm thinking, it just HAS to be a defective Duty C. Can't take it back to that dealer now, so I ordered another one, with new gaskets for everything I had to remove. Installed it, no problem. DANG!! Still no Rear wheel drive! So I pulled the TCU codes this time. Code 93 - Rear vehicle Speed Sensor. Well the rear sensor is part of the Trans wiring harness, so I order and install the trans Wiring Harness. Button everything back up.... still no Rear wheel drive. So I ask the dealers Tech guy what would cause error 93. He suggested the Reduction Drive Shaft, as sometimes the welds on the Stamped gear shear off. I knew from the last time that I was in the Extension case, the stamped gear was on and looked great, and it would not spin independently of the Reduction drive gear, so I was a little reluctant to replace it. But I went ahead and ordered up the shaft, gear, bearing, and seals. I pressed all together, then dropped the Extension case again, and pulled out old reduction shaft and installed new reduction shaft. Still no Rear wheel drive. Soooo.... I am at a loss as to what to do next. Does the tranny have to come out and get rebuilt? Is there anything else I can check before this? Also, I am not a car mechanic, just a "Weekend" Mechanic. But I am a certified A&P mechanic. Thanks guys. If you need them, I do have the list of the part numbers for everything I installed, as well as the part numbers for everything the dealer initially installed.
