I had a freak occurrence the other day: one of my CV joint bolts backed out, and the half shaft flopped around and ripped off the speedo sensor that's on the drivers side of the transaxle.

With the sensor sheared off, I've lost odometer and speedometer. Is this salvageable by just installing a new speedo sensor, or is it getting way more involved than that?

I'm attaching some pictures of the damage...

Thanks for any help...

Cheers, Gary.

 

I think all you need is a new sensor (check with PartsHeaven, since you're so close). IIRC, in that last picture, you should be able to pull off what remains of the sensor from the wiring at the rectangular connector. As for the rest of the sensor in the tranny, it just twists right off from a second piece that actually goes into the tranny.

 

Ditto to what Joe said. Easy repair there. Just pick up another sensor and r/r.

 

You have to put Porsche and BMW cv joint bolts on the same way you put wheel lugnuts - cross-pattern. If you go in a circle, you will load one side and they will back out. The torque specs are low on these, too. Only around 36 foot-pounds.

 

I had the same issue on my turbo S.

I got a new speedo sender for like $50. Easy replacement as it screws in and out.

CV joint bolts should be attched with blue loctite and care taken to ensure that threads clean with no grease as this prevents the loctite from working. Also use new bolts as old ones streach and also tend to back out.

 

Thanks all!

I'll pick up a new sensor. Also, good info on the tightening pattern and the loctite (plus using new bolts). I had tightened them criss-crossed, but I hadn't used loctite...
