Thank you, Bob, I will check the trailing arms and see about
replacements. Here is some info: Neither of the coupes has ever been in
an accident. In our cars, there is not enough clearance from the torque
tube to bend the crossmember. Using taller springs to lift the other
coupe (my friends 77 V6) a whole 2 inches reduced camber by only half
degree. I have not looked at the sub-frame bushings, but the guy with
the V6 coupe and the more severe camber problem has looked at his and
said the looked okay, plus the car handled too well to have busted
bushings (he won the Greek Mille MIglia classic race with it last
October, a 1975 Porsche 911 was second). So the search continues, and I
alternate between feeling frustrated and elated as I am fixing the car
but mostly elated.
Thanks again
Thanos

Subject: [Peugeot-L] 505-504 Excessive negative rear camber
I've heard the story about the crossmembers bending and it just dosent
compute
there isn't enough space between the crossmember and the torque tube to
bend
the cross member up enough to reestablish 0 deg camber.
I've changed the trailing arm bushings and seen no improvement in the
camber.
Raising the rear springs with shims achieved some correction but to get
to 0 deg
my TD would look like a funny car.
I'm convinced that the real problem is the trailing arms are bending
because they
are under engineered aka weak.
You could make wedges that would go between the trailing arm and the
bearing carrier.
Something that was 3 mm thick at the top and 1 mm thick at the bottom
for instance.
This would tilt the top of the wheel out.
If I hadn't flunked trig I might be able to describe the calculations to
figure out how much wedge to
get a 5 deg neg camber back to 0 deg.
There are wedge shims made for the various American cars to do this
correction; mostly front wheel
drive though. The Merkur XR4Ti guys are shimming their bearings to
correct splayed rear ends.
The best fix would be new trailing arms. Perhaps an even better fix
would be to bend them back and
beef them up with some fresh metal.
