Sorry for the delay in replying.
Heretic?? Probably! They certainly do corner flat.
I removed the sphere and noticed some congealed antifreeze and dampness. So now need to source a decent one. Are the front ones easily modified to fit the rear? They seem to be easier to find.
I also noticed excess play in the knuckle joint and bought a new Lucas one, which was £££. To my surprise the new one had almost as much lateral play as the old joint! Is this normal?
Noticed the pipe join from the rear sphere to the mid section very corroded too, so would like to replace.
Has anyone on here got a sphere and pipe for sale please?
