If your gunna do the body mounts, undo the top radiator mounting screws, so you don't flex the radiator when jacking up the front of the body.

I think it is the diff because I did
a tight U turn and it felt fine
until one of the tyres squealed
a little bit
as the clunk happened.

It sounds like you have 2 separate issues. 1stly, your rear diff is worn & has too much backlash, which is why the "slackness" gets taken up when you accellerate. 2ndly the clunk is most likely your panhard rod- either the bushes or where it mounts onto the chassis. Check that the bolt eyelet on the chassis is round & not egg shaped & torque the CRUD outa that bolt. I mean SWING off it!!! Also check your radius arm bushes. They'll cause this as will worn tie rod ends.

I jacked the rear axle up,
undid the tail shaft from
the flange, fitted the
flange tool I made last
year and used a long piece
of pipe on a breaker bar to
torque the nut up about an
eighth of a turn. I also used
a tyre lever to recheck all of
the rear bushes. I also pulled
the top panhard bolt out and
checked the bolt holes. After
re-torquing the nut super
tight I took the Old Trol
for a test run to a court and
did a few figure eights.
There is a definite
improvement. Some
of the bushes are getting
long in the tooth and will
be replaced when cash is
available.

With the help of a
mate, who owns a
hoist, I torqued the
flange nut another
eighth of a turn.
The diff now has a
slight breakaway
torque, which is what
the manual recommends.
The test drive was
smoother too.
I found that the lefthand side engine mount had also let go. The clunk has almost completely disappeared since renewing the mount. The diff probably needs to be checked properly. When finances permit, I would like to get the diff shimmed a bit tighter.

@ MN I have laser cut washers if the body mounts are out of round, [weld on]
panhard mount on the chassis
Have all the "Clunk" jokes been done???
