I have recently found you after being a member of the 205GTIDrivers forum for a few years.
My daily driver is a 1995 405 GLX 1.8i with the XU7 engine.
Recently I have had a whining / grumbling sound from the front and having recently replaced the wheel bearings, I suspected the diff.
I dropped the car off at a local garage to give me an estimate this morning and they have said it is the diff. The receptionist said I needed a new gearbox when she phoned me, but it happens in neutral as well so I knew she had got something wrong.
Having looked on the Peugeot public servicebox parts catalogue, it looks like I can buy bearings for the diff, is it easy to remove the diff?
I think for the 205 with the BE3 it is a couple of bolts and it drops out. Has anybody got any photos?
Thanks
Rob
