348 speedo trouble

Have exactly the same problem. Will take a look based on the info here.
What about sources for the sensor? Is it a Ferrari piece?

 

I obtained the sender from www.eurospares.co.uk .Part No 393650106 ,washer part No 10263460. It needs a 32mm socket to get sender out and idealyneeds to be done from underneath the car. Good luck ....

 

Have the same problem
If I unscrew the speed sensor is some oil comming out?
By the way how many pounds need to apply on the wheel nut?

Sorry,cant tell you as I got it done for me,however it was while I waited so I dont think any oil would have come out.No idea about torque though.

 

I find is 72 lb/pounds for the wheel nut

Still need to find the problem of the speed indicator.

 

What does it mean when it works sometimes and sometimes it doesn't?? Thats what happens to me.
