mayf,
I think the idea behind the Panhard rod is to keep the rear end and axle
from rotating on torque reaction. When lots of torque is transmitted to the
rear end, it tends to rotate (in the axis along the drive shaft). This
results in applying more pressure to one spring and less to the other. Not
a good thing. The Panhard rod is supposed to keep this from happening.
When the rear end tries to rotate, the Panhard rod is supposed to go into
tension (or is it compression?) to keep the rear end from rotating. Our
Limey friends, when they put a Panhard rod in the Tiger, assumed that the
Ford engine rotated in the same direction that British engines do. Well it
doesn't. As a result, MK1 and MK1A Tigers have the Panhard rod attached to
the wrong side of the car. Maybe it has something to do with driving on the
wrong side of the road or something like that. I guess the arrangement
would be correct for an Alpine, if they put a Panhard rod on the Alpine.
Anyhow, in a MK1/1A the Panhard rod pushes when it should pull. Maybe
that's why they like to tear out, but I doubt it. This was corrected in the
MKII.

Subject: [Tigers] Speaking of Panhard Bars...
Are there any other cars that use leaf springs like our cars and a
panhard bar? The use of a panhard bar in our case is just counter
intuitive to me. The leaf springs keep the rear end located and that
would seem to make the panhard bar redundant. Yeah, I know about wheel
hop, but a panhard bar or any other kind of lateral location linkage is
to keep the rear centered. If I put coil overs on the rear of my car,
then, yeah, a locating bar would be needed, as well as some trailing
linkage for fore and aft movement.
So why did they install it? Did the Alpine have one? .
