Sure grip question

Just a little extra . Greg said above doing the break-away test with a set of axles. I cut 2 axle stubs about 6'' of the spline area. Using a grinder flattened spots to chuck the stub in a vise.Place the sure grip on the spline stub,insert the stub and try to turn with a pipe wrench.Resistance should be felt till break-away.I'll do this with the cone type.
As said above the clutch type that is rebuildable,I agree,check and replace the worn parts and be done with it.
