I have a Traction-Lok...I know the "Detroit Locker" makes noise...
: Sorry boys, but SOME of them DO make noise, a kind of chunk-chunk-chunk as the clutches grab and release
: as you turn a sharp low speed corner. The more performance-oriented rebuilds seem to do this more often,
: as the tricks to make it live take away some of the Detroit mandated NVH requirements . It is not a metallic
: noise, and you can feel it more than you can hear it. I'm talkin Traction-Lok rear here. Here's how to check it:
: Put it in neutral, and jack both rear wheels off ground. Figure out some way to turn one wheel while holding other
: stationary( I remove wheels, use a big buddy with a big breaker bar, and me with a 250ft-lb beam torque wrench).
: Turn one wheel against the other until it slips. Did you hear the noise? How much torque did it take?(The more
: the better in my book). As the differential wears, the torque needed to do this will decrease, and specs are
: in Ford shop manual.
