How many different types are there - and what model/years were they.

Cheers.

 

BTT - would also like to know.

 

im not sure what ur thinking of are u thinking about the knuckle if so theres 2 types i think,
theres the sold bearing type (that uses a solid bearing) lol
and the split bearing just like the rear drum bearings thats the way i think ov it its usualy the mk3 fiesta knuckle and the mk3.5 fiesta knuckle nothing in it realy its just the different type ov bearing that goes in it

 

2

but i do not includ the hub or bearings, im talking about the hub housing it self, there are mk3 ones and mk3.5 ones.
i got one of a 1.1 once to replace a bad one on a mates FRST, no difference at all.
however bearing size does differ and so does outer cv joint size so the hub it self will poss differ on some models.
the hub housing on a mk3.5 is a little different, the bottom ball joint hole is a little bigger and i belive the hole for the shock is a little smaller
