Sierra LSD; I.D. from a photo ?
Is it possible to identify a Sierra type LSD (viscous) form a photo?
One often see's images on Ebay etc with the back cover removed and I wondered if there was any tell-tale signs to look for?

The one on the left is LSD
Not easy to tell from a photo
Turn input shaft both outputs turn the same way
I eat to survive
I drink to forget
I breath to pi55 my ex wife off (and now my ex partner)

this is true for limited slip and open diffs

But if you try to stop one of the output shafts:
The open diff will let you and spin the other faster.
The LSD will not let you stop one output shaft.

If the rear cover is off you will see a split line down the centre of the crown-wheel flange with the viscous LSD model.
The standard open diff has a one piece crown wheel mounting flange.

This is in my car. 7" viscous LSD. Ford helpfully often write the ratio as shown.

Ho ho. 3.62 written inside. Ford always did this. Handy!
