Incidentally, the book recommends Castrol Hypoy rather than Castrol EP90.
And what brands are GL4 and GL5 free at the moment?

I'm pretty clueless about this as you probably guessed, but it's my
impression that all (?) gear oils are either GL4 or GL5 specification
and that if neither is mentioned, assume it's GL4.

Sugest you forget about oil its a wild goose chase and change the right
hand rear wheel bearing -- symptoms are classic.

I only mentioned the oil issue as a by-the-way after seeing the notice
on Canley Classics' webpage. You're right, whether or not this is
something to worry about is drifting away from the topic of the thread.

I couldn't find anything on the Canley site this morning, but a Google
search found an American web site for owners of British cars. They
specifically say that GL4 is OK but do not use GL5 oils...
I am going to ignore the gear oil issue for now. I am pretty sure my problem
is not in the diff.

I have arranged for my car to go on a hoist tomorrow. Then I will find out
whether anything is more obvious when I can walk underneath it with a bright
light. The garage also has a rolling road, which will make it possible to
listen for noises from outside the car while the transmission turns.
Identification of the source of a noise from the drivers seat is never easy.

In view of the help and interest so far (thanks for all the suggestions), I
will report back what I find.
