Is there any chance that the flimsy cross-member that holds half of the diff
mounts has come partially free from where it is welded to the frame? That can
be hard to spot as the metal just separates and leaves what looks like a
joint, but is just held in place by weight. I had to solve that one. Normally
would not be eliminated by use of emergency brake, but who knows. A full break
there would hammer from the shock-absorber action (assuming you are still set
up with the Armstrongs), but I mention it as a "grasping at straws" thought.
Otherwise, one wonders if the hub bearings are stiff/shot and the clunk is
actually the sound of them breaking free. Do the wheel rims get excessively
warm when driving?

List,
Ever since its restoration many years and thousands of miles ago, ...
We have examined the diff mounts, replaced all universals on the drive shaft
and half shafts, pulled the half shaft apart and greased them, etc. etc.
We're
about to change the diff, even though neither of us believes the diff to be
the problem. In other words, we're down to grasping at straws.
This morning we made a new observaton which is why I'm appealing to the List
for insight or solution.
If the E brake is on while we attempt to move the car forward or backward,
there is no evidence of this "clunk". It occurs only if the car moves,
however
slightly.
I would assume this evidence eliminates the driveshaft, diff, and half shafts
as the cause of the problem.
Does the List agree?
Then, what's left? Brakes? Wheels?

Hi Ed & list!
PLEASE keep me informed on ALL the Info that you have received on this
subject, because I'm having the same problem.
I'm at the point where you are in wanting to switch differantials, too. But I
haven't tried the handbrake test yet. thanks for the input.
> Then, what's left? Brakes?
It could be a brake shoe spring retanior being to loose? But? How do you
check
that with the wheel & drum on?
> Wheels?
I'm thinking of rebuilding the hubs, but I've heard on the list that there
are
CV joint 1/2 shafts that are better. Now if I decide to get these, then do
you
know if they come with new HUBS? I'd hate to rebuild the hubs to find out
that
it was a waist of time because the CV units come complete with new hubs. Do
you know anything about these CV units & who or where to get them?
Again, I'm VERY concerned & interested on this thread.
