Drivetrain Testing traction lock in the car

That seems pretty subjective to me. The last time I repacked mine, I did it with an extra clutch. It's stiff.

I agree that your method can certainly provide you a reference but what do you compare it to?

I'd do it. Then I'd rebuild it. Then I'd do it again and make a thread about it.

Found this online for GM Eaton style posi.


The method used for determining clutch and system performance to a testable standard is = (must resist or not not turn @ or below 250 LBS torque) A little old school but a test used years ago when I worked on the Dealership Heavy Line. Use a torque wrench to measure the minimum allowable resistance of the posi assembly. required to turn one axle while the other is held in place. If it fails to turn at 250 LBS then is passes the the clutch test.

Rotational force must be centered on axle not lug nut.



(vintage mustang forum);
The Ford shop manuals say's that with one tire on the floor,and with a tool that centers the torque wrench with the axle on the raised side. The constant torque required to spin the tire should be at least 40 ft lbs. It also say's that the break away torque may be greater. Like 200-275.
