Default 'Cracking' noise from rear diff.??

Drove my car (2003 JDM STi) today for the first time since November. Has been in storage due to extreme weather. There was a bit of a thaw today so took the opportunity to go for a bit of a blast.
When pulling away from junctions there was a very noticeable 'crack, crack, crack' sound. Sounded like the rear diff. The roads were dry and free of ice where this occurred
I've heard this noise once before when pulling away quickly to the left at a junction. I assumed that it was normal noise as the LSD did it's stuff.
Today, however, it was much more frequent than before even under mild acceleration while pulling away from junctions. I could even provoke the same noise under heavy acceleration in moderate bends.
I took the car to a large empty car park and did some circles, clockwise and anti, and after several in each direction the noise disappeared and did not reappear for the remainder of the drive.
Is it possible that the long lay-up has caused some problem? Or does this sound pretty normal?
The car has covered only 5,000 miles
Any advice or comments would be appreciated.

Please post in the right forum.

There are many experts on different facets of Subaru information. They tend to view and respond in the forums where their knowledge level is highest. By posting in the inappropriate forum, you are not only diluting the wrong forum, but short changing the search results of others and increasing the chances of an expert missing your question.

HAve you checks the rear diff fluid lately? when was it last changed? all those questions etc...

You could of had a metal shaving and not enough fluid in the rear-end causing something to go a bit off.
