Lower Ball Joint, Bearings, AntiRollbar Link??? -=thunk=-

DaveW · Post by **DaveW** » 30 Apr 2006, 19:07

According to my Haynes Xantia book :

Lower arm balljoint to hub carrier......... 250 Nm..............185 lb/ft

Strange that as on the BX it is 50.6 lb/ft.
I didn't think that the design was all that different.

Thats erratic Dave -
BX balljoint torque is as hard as you can get it not shearing the balljoint itself. Its the same as the hubnut (drive axle center nut) torque - 270Nm/196LbfFt.
This is not found in the BOL - however the BOL states the torque figure for the smaller nut securing the arm to the joint - which is what you found

Anders,

Perhaps I have misinterpreted what it says as the descriptions are different but :

"..Suspension strut to steering swivel .. 50.6 lb/ft .."

seems to be the one ?

"..Suspension arm to steering swivel .. 21.6 lb/ft .." is the small nut on the ball joint, yes.

Throughout that section the ball joint is described as :
".. Steering swivel (knuckle) bottom ball joint .."

Dave.

"..Suspension strut to steering swivel .. 50.6 lb/ft .."

- that is the clamp bolt/nut on the hub that holds (clamps) the strut end to the hub carrier. Nothing to do with the swivel ball joint.
As I said : the BOL does not mention this torque setting on the BX. And I've got 3 different copies of the BX manual : 2 different issues of the brown/grey and 1 of the later blue issue (spanner ratings sytem).
None of them mentions this torque setting. Except for the 2 settings you have found.

How's your French everyone? Taking lead from the Haynes thread elsewhere here's the lowdown from a VERY CLEAR side elevation illustration from L'Expert Automobile...

Couples de serrage [en daN.m]

Bottom balljoint nut [aka Fixation rotule] 4.5
Hub nut/driveshaft CV [aka Fixation transmission sur moyeu] 32

BUT

the actual balljoint to the actual hub [Fixation rotule/pivot] 25

Hope this clears it all up!!

Go on ask me for another torque setting!! [please don't!!]

Anders,

That's very confusing and very remiss of them.

In the text it says the usual " tighten to the specified torque " and one would expect that torque figure to be printed along with the others.
From the quotes in my post it is easy to assume that the description alied to the 50.6 figure does refer to the ball joint to housing especially as the third quotation (Steering swivel etc.) is used to describe the ball joint thoughout the section.

That is certainly how I would read it.

Dave.

I'm really truly sorry Dave -

I did'nt wrote the BOL manuals - honestly

But 16 years with different BX'es - and my 3 BX BOL's have teached me a lot - the hard way

Anders,

Despite serious doubts, I'll accept that you were not responsible for writing the BOL's ..........

Given that the Haynes books are, to say the least, a bit 'iffy' and the Xantia one in particular seems to very poor, can you recommend another source(s) of accurate information other than the Citroen workshop manuals (and this forum) ??

Dave.

Ok, I now have sitting in front of me a copy of the genuine Citroen service manual. (At least the suspension section, I don't have all of the book

)

The figures are:

ball-joint fixing to swivel - 25 m.daN = 181.25 lb/ft
ball-joint fixing - 4.5 m.daN = 32.6 lb/ft

From the horses mouth so to speak...I have all the other figures for the suspension joints too if anyone wants them.

Regards,
Simon

There actually seems to be more than 3 volumes per series of Xantia...

If they're anything like my Xm ones I've only got part of the Xant ones too. No wonder the garages are quick to try and get rid of these as they'll take a load of room combined with all the other models in the range with their extra supplementary info etc!

Good old ebay!!

Yeah, I only have a small fraction of the total Xantia manuals... I have only copied the suspension and hydraulic section, which alone is hundreds of pages.... I think the complete manual is close to a couple of thousand pages broken across about 4 large ring binders

Am I the only one to find the terms to be rather imprecise.

"swivel" I assume has to be the hub-carrier. Is this a translation thing or how it would be described in France. ?

Pretty poor if they cannot describe things in a sensible manner in the actual Citroen workshop manual !

Dave.

Dear Dave -

If you stumble on such peditesses in the manual - you'll never, ever get to any real work

Honestly though : manuals were written in french - then translated to english - by french engineers - and then again interpreted by some poor technical educated desk clerks at Haynes.

Now - you just wait until you get a chance to look in Citroen spare parts lists - which is a mix of french & english - with horrible spelling, translation and typo errors.
