96 Outback... AWD Auto trans 170K poorly maintained miles.

Drives smooth down the road with normal driving.... no unusual noise or vibration until....

You make a U TURN or sharp corner... then it clunks and bangs in the back. Sounds like the diff. Do they have a Locker or limited slip?

Any Idea's??

Interchange questions.... I have a chance to buy a 98 Outback... Auto trans AWD with a bad 2.5 engine.... Rusty body... not worth repairing

Would the Trans & The rear end be the same as the 96? I suspect the rear ends will bolt up... but are the Gear ratios the same?
Will the 98 Trans work in the 96 car?

Thanks for the help.

Symptoms are similar to those experienced when the AWD transfer clutch is engaged when it should not be. It's called "torque bind", and it causes the wheels to skip/hop on turns. Clunks and bangs could be a good description of the sounds that can appear, especially if parts of the drive train are worn.

Sometimes multiple changes of the ATF alleviates the symptoms; in other cases the transfer control solenoid/valve, or transfer clutch plates have to be replaced. Also, the car should have FWD fuse socket on the upper right side of the engine area firewall or the right side strut tower. Insert a fuse (any value) in the socket. A FWD warning light should come on in the instrument panel -- the fuse is disabling the AWD, turning the car into a FWD. With the AWD disabled, see if the clunking and banging stop.

Also, when the key is turned to ON (RUN) but the engine is not started, do the CEL and AT Oil Temp warning lights come on (they should)? Do either stay on after the engine is started, or flash (they shouldn't)?

Do a search here for the "torque bind"; there will be lots of hits, along with suggestions to diagnose the problem.

p.s. good idea to link to your other thread on engine replacement: http://www.subaruoutback.org/forums...53818-96-outback-2-5-2-2-swap.html#post525128
