Hi Patrick,

Do you mean the front hub or the back hub.

If you have any photographs it will help people see what you need.

I mean the front hubs, the back is no problem, I want to know from wich car I've to order

see here:
http://www.burtonpower.com/parts-by-fitment-type/parts-by-car-model-ford/ford-sierra.html?product_area=598&product_group=345

there are only 3 types of front wheel bearings - ordinary sierra, 4x4 or cossie 2wd



these are the normal ones:

Hi Patrick

Perhaps you asking how to attach the Sierra hub to the lower wishbone. ?

You will need to get a ball joint from an Austin Maxi.

The Sierra hub will need to be reamed to accept the taper of the Austin Maxi ball joint.

Hope that is of some help.

thanks that was my question

Hi Patrick

Gave this some more thought.

Assuming you are going for a Haynes type build, you will need Ford Transit Drag links to attach the top wishbones.

Drag links you need are right hand thread & M14 , 1.5mm thread pitch if memory serves me right.

You will also need to make or buy adapters to fit in the top of the Sierra hubs, these fit where the suspension strut would normally fit.
These are commonly know as mushroom adapters.
On the Haynes roadster, the tapered hole in the adapter is offset.

thanks now I know a lot more
