rear speed sensor???

[SmokeyF350]

my rear speed sensor went bad so I was installing a new one and when i pulled it out it was broke. when it broke it let the gear in the diff or what ever that is slip off. i guess my question is are there anything else that holds this gear in its place to run beside the speed sensor?

What truck is this? Most likely you're going to have to pull the cover and take a look inside. The speed sensor doesn't hold anything in place.

my truck is a 06 f350 crew cab, just come in from pulling cover . The speed sensor ring is just floating beside or on the big gear(cant be right) found a sheared bolt from the housing oppisite side of the big gear almost the whole thing was in the bottom .nothing looks chipped or bad what holds the speed sensor gear on?what should I do,was some scaring on the housing looks like from the worm gear? any help would be grateful. thanks scott

It's definitely not supposed to be floating around. It should be bolted to the carrier in some way. I would clean the oil out, bolt the gear back on where it's supposed to go with some lock-tite and put it back together.
