rear axle width

[thailoz]

Ok I have tried to find this in search but not a clear answer.

As some of you may know I am having great difficulty in finding a donor,

what I need to know is what is the total width from hub face (wheel mounting face ) to hub face of the sierra rear.

I may have to go live axle

but we will see

Just found this

Ford Sierra 2.0i is a sedan/saloon with 5 doors, 5 seats and rear wheel drive (RWD). This model has been released in 1989. The automobile is 1372.00 mm high, 4424.00 mm long and 1695.00 mm wide. Moreover, this model's wheelbase is 2608.00 mm, its front and rear track are 1451.00 mm and 1468.00 mm respectively.

Just measured my car and its 1400 between the lip of the drum backplate so 1468 is about right

The track is measured between centrelines of tyres. So, the width between the wheel mounting faces (including the thickness of the drum, mind) should be 1468 + 2 * 35 (the wheel offset), so 1538 in total.

Wheel offset ET for Sierra was 38 and is a minus figure i.e. the amount the wheel centre line goes in towards the body relative to the wheel mounting face
Lets not confuse matters
As I said earlier in my post I have measured to the drum back plate at 1.4 meters, data quotes 1.468 and unless you have measured it that's what it is

Well, I don't have the roadster at hand to measure the geometry, and mine is buggered now anyway, but I have 2 spare brake drums. Their thickness from the backing plate flage to the wheel seat is 65-70 mm. So, if we combine your measurements and mine, ~1400 + 2 * 68 = ~1536.

And you're mistaken about the wheel offset. Sierra's offset is positive and positive means to the outside.

No I am correct on offset
Look at car wheel bible
ET without a - is in
With - is out compared with wheel centre line
I.e. ET 35 means your inner wheel face is closer to the car
Escort run ET from 22 to 15 a d have a deeper dish
I run ET 23 on one set of wheels and they stick out further than ET35
A lot of deep dish Escort wheels are 0 ET you can see the difference

The "ET45" figure below that though symbolises that these wheels have a positive offset of 45mm
In other words, they have an inset of 45mm.

I can explain it to you but can't understand it for you
