noticed van was leaking looked underneath and noticed a crack in a 'casing',. Basically the area/housing that is cracked is where the inner cv joint is housed on the passenger side....my problem is that i dont know what it is called to by a new one....looked like there is a sensor that goes into the top too...anyone know what this is called and even worth fixing??

 

 

there are three bolts that attach this broken housing to tranny
