Technical Dimmension of Ducato hubnut?

[Reidar]

This weekend i plan to change the left front upright. The shock absorber is leaking.
Will I have too take the driveshaft out of the hub to achieve this?
If I have to, what are the dimmension of the hubnut?

I have done similar things on my Peugeot 106Rallye and other small hatchbacks before. Is this pretty much the same or is there major differences I should be aware of?

I can't answer this I'm afraid, but there have been a few good threads on this recently. While it's off, check the top bearing, they're prone to failure, so it's worth swopping it if it shows signs of roughness or tightness.

Hi mate
I have just done mine all you need to take off is the leg itself,but as mikey said check the top bearing,i personally replaced mine as you can't really tell how worn it is,as for the hub nut for future referance the one i got with my c/v joint was 41mm but the one on the moter was 50mm still worked ok they must be cutting costs,the bearrings were £13.50.Good luck.

Thanks guys!

I replaced the leg last night. I was too lacy too secure the driveshaft with wicegrips and straps as I normally do with the Peugeot 106 and off course I pulled the shaft too far out and lost about half a litre of gear oil

The new leg was a second hand one from a low milage car and came complete with topmounts that seemed fine.

the cv nut on a 55 plate 2.8 ducato is 50 mm

the nut on my c/v is also 50mm but the c/v i bought was only 41mm same c/v just a differant nut size.

The hub nut on my leftside driveshaft is 49/50 mm. The nut on my rightside driveshaft is 40 mm!

I have the Automatic gearbox.

Out of curiosity...does anyone know why they are different sizes?

Hi, old thread but still relevant!
I have bought a new CV - but my 45mm socket won't fit the new part which is 50mm , dammit.
I'm struggling to find a 50mm socket that will fit in the hub opening now. (Only 1.5mm clearance around the 45mm impact type socket)
Good job I checked before destroying the original hub nut!

yeah...I had to buy that 50 mm socket separately...and on a 3/4 inch bar .... its torque setting is very big! Glad i wasn't alone and my post helped someone else!

Thankyou!
One more thing though.
Did you have trouble finding a 50mm socket that fits inside the hub ok?
Even the 45(6?)mm impact socket barely fits in there.

40mm? The plot thickens!!
I imagine that the larger socket sizes allow a little more leverage to be applied before failure.
The nut seems to have been enlarged during production due to problems in service.
