check for a loose vacuum hose. Spray around the engine with brake clean while engine is running, see if the car surges.

Always forget about the filter. I probably should do it on the last flush. http://www.napaonline.com/Catalog/CatalogItemDetail.aspx/A-Trsax-Filter-Kit/_/R-ATP18561_0456358427 This one?

define slow and sluggish. What engine do you have? does it feel like a misfire?

Was going to say. Cylinder needs spark/fuel/compression. Start swapping injectors/plugs and compression test lol. Good job

Will do. Hopefully flushing it will fix it. Currently trying to figure out why cruise randomly doesn't work

Oops . The first flush made it sooo much better. Before it binded REALLY bad when I cut the wheel like 1/8th of a turn. I couldn't even drive the car. I had put it in FWD mode to drive it. After the first drain/fill, I am now able to drive it in AWD mode. I can feel the shudder on most 90 degree turns, but it is no where near as bad. I will try a few more drain and fills and try more posi additive. Good news on that I can rebuild just the clutch packs without re-doing the whole trans. Any recommendations on where to get the parts/write ups on how to do it?

If I put the FWD fuse in, the binding stops. The binding is only there if the car has the AWD enabled (FWD fuse pulled). are you just saying to leave the fuse in when I drive it, and only pull the fuse when i do a drain/fill?

Makes sense. So keep driving it and flush it with the fwd fuse in? How will I know if the shuddering stops though

Welp heres an update. The grinding noise out of the right rear was the backing plate. The bottom was rusted and hitting the rotor. I smashed some of it out and cut some of it away. It is mostly gone now. It is KIND OF there, but gone. Bearings are fine. Put 4 wheels and 4 new tires on it. I can now safely go over 40MPH lol. I did a trans service, the fluid was sooooooooooo brown. I put 4 quarts in like a moron, so it was overfilled, and I added 3OZ of GM posi additive with it (spoke with a seasoned scubaru tech, he said he does it all the time to cure it). I drained it down till it was properly filled. The shuddering has toned down A LOT. It is only there at extreme turns. So maybe keep flushing it?

Will do. I am going to fix the tires first... as I can't even drive the car! Picking up a set of 15" legacy WHEELS (not ugly steelies) this Friday. will then investigate wheel bearing

Fixed right rear caliper, replaced rear brakes. Found left rear tire has a flat spot. Could maybe cause the "torque binding?" Its bad like can't even do over 55 lol (vibration from tire). Also found the bottom parking shoe spring on right side is hitting abs wheel? It hits hard when making a right but doesn't hit when making a left. Bad bearing?

I am on my way now to get fluid.

I had an 86 vf500 interceptor as well haha. Yeah Hazelton has many Subaru's!

Awesome thank you. Put fwd fuse in for now. Will buy additive and trans fluid. The fluid is BROWN in the car

Yeah that is what I thought. I'm not sure how subaru's AWD system works either, so I don't know if its the rear or the trans causing the binding. This is the thread I was reading on. http://www.subaruforester.org/vbulletin/f88/do-i-have-differerential-transmission-issue-awd-binding-39121/
