Thank you.
Noise is independent of engine rotating; most apparent with engine off in
neutral and coasting - in the stillness of no engine noises.rg

Is your fan belt in good order. I had one that was 'lumpy' with some cross
sections being different to others. I had great difficulty working out where
the vibration came from. In the event it was the car that told me by fracturing
the dynamo bracket

Not a lot of progress...
Brake cable is well clear of propshaft and securely clipped.
Universal U joint/spline phasing is correct.
Been doing lots of listening with stethoscope.
With propshaft disconnected, am able hear noise in 2nd or 4th when slipping
clutch (reduces speed)
Assume is the same noise and less distinct because of the engine noise.
Not nearly as distinct as when shaft is connected and rear wheels freewheeling
in neutral and engine off.
Loudest area seems to be rear GB casing near rear bearing.
This still does not sound like a bearing to my ears ?
Plan to try to get a 2nd expert opinion with younger ears !

Drive shaft hitting the handbrake cable when the car is jacked up. Probably
will go away when sitting on the ground. David

Subject: [Healeys] Mystery noise AH people - fighting a noise in my BJ8 that
may or may not be
serious.Reluctant to tear out the tranny unnecessarily and then to find it was
something simple !
Notice it at low speed (probably exists at driving speed but too much wind
and engine
noise) if shift to neutral and cut ignition to minimize engine
and exhaust noise.Noise is pulsating - like a tire with a bad spot but seems to
be at
prop shaft speed. At first thought that it was at wheel speed and from R
side.So changed out the R wheel bearing.No improvement Then while looking below
noted that universals had some play.So changed out both universals.Rear brakes
not dragging and no binding of wheels.No improvement. Did listening on hoist
with others listening too. Consensus was that there
was a noise at rear OD area as well as the pulsating one. So pulled annulus in
situ and replaced both rear bearings. Quieter but
still the pulsating noise while coasting in N. Sound file enclosed is a road
test from about 15 MPH then shift to N and
cut engine. Tunnel cover off.
Able to replicate noise with engine on axle stands but not by turning a
rear wheel by hand or with an e motor.
Noise does appear to come from transmission.
To verify is not diff removed one of the rear seats and noise doesn't
appear to be coming from diff area.
Disconnecting prop shaft to isolate diff not possible as need the inertia
of the rear wheels to produce the pulsing. About 5k miles ago I changed out the
larger OD front bearing (sourced from
Moss ... ?) in the OD.OD works fine and transmission shifts and works OK
without unusual
noises. The pulsating/cyclical nature of the noise baffles me and not
consistent
with a bearing failure ? Given that it occurs in neutral with no gears meshing
it surely is not a
bad gear tooth etc.
OD not engaged so it is locked so not likely there.
Removed gearbox top cover and did inspection - nothing obvious.
So to my mind this only leaves the GB rear bearing ?Or maybe a broken circlip
or thrust washer and probably on main shaft
external to gearbox ?
or half shaft ?
Any comments/thoughts appreciated from the more experienced
among us.
