Does anyone know what the back lash should be on the on the prop flange. I have .011".

When I rock the prop shaft back and forwards there is quite a clonk just like a nackerd diff.

From my old MK2 Cortina days I'm sure pinion to crown wheel used to be .003-.004", which translates to an awful lot less than .011" at the input flange.

I have also just about managed to flush all the black goo out with lots of diesel and patience, not a quick job to say the least especially when I took the drain plug out and got most of it up my sleeve.

Now I plan to replace the egg cup full of tar with 450ml of Millers EP140 and hope it will run a little quieter.
