The image of the 100nm torque was only the initial torque before fully torqued to 290nm . Torqued both nut types to 290nm no issues. The strange nut you refer to has been used also on the rear hubs ( slightly smaller version) , and on other models too in focus  to torques of 235nm ok.

Did you try to re-use the stacked nut instead of replacing it?  Those ones really are single use!

Just for reference, I had a loose front wheel on my Mk6 from the day I got it...thought the bearing was knackered...once I'd bought the bearing I popped the centre cap off and went to loosen the hub nut...turned out the nut was only finger tight! Bearing was fine, just someone had left the nut loose after replacing it prior to my ownership.  I torqued it to 290Nm no problem.

Thanks again Ian,

Yes, you're right on the 100 NM

My mistake;

I've just re-checked the Ford instruction and indeed the 100 NM is the 'pre-load' torque.

I still find it impossible to believe that my type of hub nut will withstand 290 NM.

The last one certainly didn't.

However, The one that stripped was included with the 'LPB' bearing.  It wasn't a genuine Ford nut. Could there be a difference?

Thanks Toms,

It was indeed a virgin nut.

I've just this minute started gradually increasing the torque on both hub nuts by 10NM steps.

I'm now at 210NM (the limit of my 1/2" drive torque wrench).

Very interesting;

I've continued increasing the torque by 10 NM on both front hub nuts..

The N/S is a genuine Ford.

The O/S is LBP.

I got to 220NM with both.

I could tell that the Ford nut was performing much better than LPB.

I went for 230NM..

The Ford nut gave the re-assuring click on my 500NM 3/4" drive torque wrench.

The LPB is about to strip.

No way on this Earth will that nut reach 290NM.

I'm now minded to invest in another genuine Ford nut.

All input to this thread is much appreciated.

...and more interesting;

I continued increasing Torque on the Ford nut and guess what?

Yes, I'm at 290NM !!

I went back to the LPB o/s nut  and wound back the torque wrench to 180NM and again..

I got a 'click'

190NM, click.

200NM, errr, click.

210, no click, about to strip.

Time for another Ford nut I reckon.

Just to clear things up;

The nut that stripped and caused this debate was an LPB nut that came with the bearing and an unnecessary circlip.

I stated earlier that the Ford nut stripped.

My apologies for posting that misleading info :sad:

I'm now off to Fleabay to find a Ford nut.

Best regards and thanks again for your advice/input,

The second Ford hub nut (1008849) for the off side wheel arrived today.

I gradually torqued it up to 290NM.

I'm really glad to see the back of this job.

My word I've spent some hours on it.

I've learned a lot along the way though.

Thanks again to all who gave advice/opinions to help me along the way  :thumbsup:

I really do enjoy this website :smile:

Hi with that abs fault do you remember the fault code that came up as Iv recently got a abs code coming up C1095 that is a pump motor circuit failure and C1234 that is front right wheel sensor input missing its also blowing 30A fuses I also just changed the front right sensor with one from ebay and thought that was the end it so  I traced the wire back from the pump and theres no splits or anything in the wires so I don't know if I should blame the pump

Sorry for late reply F28 but I hadn't seen your post,

Have you got it sorted?

I don't have any record of the fault codes sorry.

I didn't ever get a 'pump motor circuit failure' reading.

IMHO and limited experience, single sensor issues are usually caused by the magnetic strip being corroded/perished on the wheel bearings.

Dual sensor codes are a nightmare.

I don't reckon your issue is really comparable with mine but please let me know how you've gotten on.

H..
