Sierra rear hub dimensions
Nile_rt - 16/4/21 at 02:40 PM

Hello, can anyone give me the dimension between hole centres of the ford sierra rear hubs used on cars with drum brakes please?

I need to order some shims for changing the toe and camber on my de-dion set up and my car is away at the moment

Thanks

I made a cardboard template when I adjusted the rear tracking on my car then transferred the shape to some shim stock . Canít help with any sizes though .

Hello,
Perhaps I misunderstood the question, but isn't the answer: "same as the wheels", which is PCD 4x108 ?
Therefore a simple drawing will give you the distance between 2 consecutive holes, which is 76.37mm if it is what you are looking for.

Sorry if my post wasn't clear. It's the bolt spacing of the bearing carrier. They look like this http://www.kitcardirect.co.uk/ford-sierra-rear-aluminium-billet-bearing-carrier-60mm-pair.html

^^^ If it's for toe and camber settings then it's the bolt pattern for the bearing carrier onto the axle/upright
(Edit: too slow.... )


While I can't get at mine right now to measure them I believe they will be the same as the disc braked cars


This one should be the same too (I just can't confirm that right now)

At least they seem to match the sizes here:

Ah OK, sorry.
In that case, the dimensions you need are the same as on part RU7 and RU8 of the Haynes Roadster, because they are he parts the Sierra rear hub carriers bolts on.

(horizontal spacing of lower holes is the same as upper holes)

I have Sierra drum brake set-up on my Haynes and I can guaranty these dimensions are correct.

As mcerd1 says, drum and disc rear hub carrier are the same, just the orientation is different.
