Hey fellow yota enthusiasts. I’m new to the scene and starting off my 2nd Gen T4R build, also I apologize in advance for my noob questions and any unclear yota vocabulary.
A Spartan locker is on order for my truck, so before it arrives I figured I’d prep the truck so I could speed up the install process. When I drained the rear diff and then began to work at removing the sensor up on top of the differential. (Im not positive what it’s called and what it does, ABS? Wheel speed sensor?) ANYWAY.. it was stuck in there pretty good, and unfortunately I wasn’t careful enough and it broke from the top, leaving the remaining body of the sensor in the differential.

1. I’m wondering if this sensor stuck in there will stop the third member from coming out?
2.Does this send info back to the speedometer for vehicle speed or is it for ABS?
-If it is for ABS(which I don’t mind not having), if I go without replacing it will it affect anything other than the abs system?

Any help would be greatly appreciated! I wanna get this rear locked today!!��

OH! And it’s a 93’ 3veezy with a M/T

I did the same thing when I put in my TrueTrac. It's easy to do.

The sensor counts the teeth on the ring gear as they go by to indicate rear axle average speed. It's for the rear wheel ABS, and has no other function. The speedometer is driven from a speed sensor on the output shaft of the transfer case, so not affected by this.

To answer your questions,
1) It won't keep the 3rd from coming out.
2) It's only used for the ABS, which on the '93 is a fairly primitive ABS in the first place. It simply looks at rear wheel speed and modulates the rear brakes to keep the rear end from locking up. Believe it or not, it uses the power steering system pressure to do the brake modulation. Obviously an attempt to get some kind of ABS into the sales literature while they were working on the 4-wheel version which came out on the 3rd gen.

If you leave it broken, it will permanently light the orange "antilock" light on your dash under the speedometer (or tach, I forget which). If you can live with that, you're good to go. If you want to repair it, you'll have to get the old one out (easier when the 3rd is out of the truck), order a new one ($100 or so), and connect it in. It comes with a pigtail and connector, but the connector is in an impossible place above the frame beside the spare tire. I gave up on the connector and just spliced the wires from the new part to the old wiring harness.
