hi olive don’t think there is a torque for this ,, there is a crush washer/ bush Behind it’s more to do with setting the load on bearings , Definitely wouldn’t over tighten,or possibly end up with groaning bearings,, you could probably just take up the play on nut and lock back in place,, this nut is normally done when setting up the diff ,, I’d imagine if it’s really loose possibly bearings are a bit worn

hi olive don’t think there is a torque for this ,, there is a crush washer/ bush Behind it’s more to do with setting the pre load on bearings on pinion gear before installation of lsd , Definitely wouldn’t over tighten,or possibly end up with groaning bearings,, you could probably just take up the play on nut and lock back in place,, this nut is normally done when setting up the pinion in diff housing ,, I’d imagine if it’s really loose possibly bearings are a bit worn,, I believe pinion bearings preload is 12-23 inlbs, But this isn’t the nut torque

Thanks a lot Chad!
Is it 12/23 inlbs or 12/13 ?

. 12 - -23 This is the rotational resistance on the bearings. To ensure they’re not to tight or running loose. Not the torque on the nut,, Could be different on different manufacturers bearings. But in the ballpark. Nut on mine was loose I just nipped it up at the time and locking it in ,,, probably most end up on the loose side as bearings wear. Unless it’s really really loose probably not a big issue.. pinion is shimmed to obtain correct set to crown gear on assembly,, I don’t claim to be a expert. But have some knowledge after doing my own diff work :whistle:

May be you are not an expert but comparing to me it looks like the same :thumbs:

Thanks a lot.

Sorry for late replay, regarding your question about the collar.


Its difficult to guess whether that missing piece could be the culprit.
Because usually those connectors on the hoses are very firmly and tightly attached to the airbox. So i don't believe that a missing collar and therefore a bit of play on the hoses (not on the connectors) themselves would cause a leak.

Usually those clamps only function is to keep hoses/pipes from dangling about and to keep them grouped together, so they don't get struck by moving parts.


Did you check if the plastic connector is ok? And if you connect the hoses to the airbox and you wiggle a bit on the hose, if its still firmly attached?

If you attach the hoses they make a firm "click" noise.

Honestly I did not checked it my myself. The car is in hands of my mechanic. I am gtransmitting to him all your advises every end of days :beer:

He ordered piece n°1 + some others small pieces. We'll see...
