So I had a bad clunking going in and out of 4WD. Tracked it down to a toasted upper differential bushing. I could lift the differential by hand.

Subaru part is NLA, but Superpro makes a replacement SPF3005K.

Tools needed are:

• 17MM
• 21MM
• Milk crate to set the diff on
• Hack saw
• Somewhat of pressing the new bushing in.
• Some way of lifting the car

I backed it up on some 6x6 to get enough room.

I couldn't press the old outer because I lacked the correct die. So I ended up cutting a slice out with a hacksaw.

I used a bolt and some washers to press the new one in.

 

So I took it for a test drive, and it was so smooth going into 4WD I though it wasn't working. Push the button and let off the throttle at any speed and you can't feel a thing. Same goes for disengaging.

Nice work. Interesting to see you use the Australian idea of milk crate !

Saves you from pulling the axles and drive shaft. Just set the diff down on the crate. Makes it a sub 1 hour job.
