i have the 8.8 trac lock rear end from a 93 explorer in my 1961 falcon , the sensor is not hocked up and i only get a one wheel burn during a burn out.

my question is -a friend says i can hook the sensor on the rear end up to a toggle to make the rear end lock up , is this true

thx nockturnal

 

The TRAC-LOCK rear end is not and electrical LOCK-UP rear end it's mechanical. It uses clutch packs with friction pads. Sounds like you need to open the rear-end up and replace the clutch packs on both sides (Ford part # F5AZ-4947-BA). You could also get the high performance kit from Ford Racing that uses carbon discs for higher torque usage (Part # M-4700-C). There is also a "S" spring that applies the required pre-load for the clutch packs. You might also want to replace it also if it doesn't come with the clutch pack kit. Don't forget to soak the clutch packs friction pads in gear-lube before installing and also add the Ford friction modifier when installing the grear lube after assembly.

From the factory, the TRAC-LOCKs are packed in this order: shim, friction, steel, steel, friction, steel, steel, friction, side gear.

The alternating pack method is: shim, friction, steel, friction, steel, friction, steel, friction, side gear. This is how I set them up for better locking ability.

Note: The electrical sensor in the rear is the ABS sensor.
