Transmission

At about 70K I had the transmission rebuilt - gears slipping etc - the usual!

Now have 110K (kms) and in the last 2 weeks have developed a mechanical noise coming from somewhere in the transmission. On getting to 50km on power up it comes on but taking off power it stops.

Have had the car inspected by 3 mechanics including Subaru service centre. 3 different diagnostics:

1. rear diff
2. gear box
3. front diff
4. also initially told that it was the rear wheel bearings

Who do you believe????

When car up on hoist and in gears, seems there is excessive noice in the rear of gear box (transfer case area).

Has anyone had anythjing like that and can perhaps guide me in the right direction.
