I've been burning through speed sensors like crazy... I broke the gear box coming out of my tranny that has the little speed sensor attatched and had a new one built by a guy who builds them custom. I replaced the speed sensor(I don't know the correct term for it) that screws into that little gear box and got my speedometer to work for 4 months or so, then that sensor quit working and I lost my speedometer again. this happens about every 4 months on the dot now and I've replaced it like 4 times and finally gave up because they keep failing. I'm at a loss here and was wondering if anyone has any ideas on what it could be... thanks

 

is the plastic gear in the transfercase worn?
every time it goes bad is the speed senser loose n the t-case?
rear yoke tight?

 

no it's still on there tight, but would it be hard to check the plastic gear in the t case?

 

i beleave you can unscrew the part that the speed senser screws into and feel/ maybe see the gear and i dont know if it is whats wrong but cant hurt to check
