Hi mates!
What is the torque of front hub nuts on 4x4?
Strange thig I saw in workshop manual.
On sierra there is a 205-235 Nm but on escort there is a 310-350 Nm
Hubs, bearings and nuts on sierra cosw turbo 4x4 and escort cosw turbo 4x4 are the same as I know.
Where is the truth mates? And if it's not a mistake in the manual, why the torques are so different for this cars?

 

it is 310-350, the other ones must be for 2wd

 

On 2wd I saw in the same manual 310-350.
I'll try to post three prints from Cosworth Workshop Manual with three cars:
Sierra 2WD, Sierra 4WD and Escort.

 

This is three parts of manual:

Sierra 2WD


Sierra 4WD


Escort


Maybe I've not understood something?

 

last time i bought new front hub nuts from ford for my 1996 esc cos there where 2 different sizes listed for it... if i remember correctly the choices were either a 20mm or a 22mm nut so i meassured mine and they were 22mm. maybe thats why there are 2 different torque figures..

 

Strange thing but I thing the difference between nuts size and not thread can't to affect to torque figure

 

obviously i dont mean the actual size of the nut... maybe i should have been clearer and said M20 or M22...

 

Sorry mate for misunderstanding. Of coarse this difference can affect on a torque figure.
And we have 205-235 Nm in a Sierra 4x4 case as we can see in a picture. Is that right?

 

i had made my bearings a few days ago on my 4x4 saff and i did the 310nm and everything works fine...

 

I do 2wd and 4wd up to 250lbft, never had aproblem.

Hi tabetha! Glad to see you here.

My trouble is that I used 205-235 Nm and it's less than 250lbft you use...

 

Just tweak up to 300nm will be fine.

Thanx all mates!

Will try to increase torque up to 300-350 Nm but it's a strange thing with information in the manual.

 

Even stranger when ford change the settings for head tightness too!!

i sptripped teh threads from a shaft at 225 lb/ft so be carefull as you do it up

 

I'll try mate but I'm a little afraid now...

 

I will admit to being confused as to why they need to be so tight, even on 2wd front.

Have no ideas. Ford is a strange thing at all.
