gov lock how too???
- Thread starter buhlandy
- Start date
Gov-lock test: jack rear end off the ground, rotate one tire, note direction of other. Opposite/no revolution of opposite tire, it's not locked up. Good.
Next test, rotate same tire QUICKLY by hand and the other axle should lock in, and you'll know it.
As to lube, I'm too lazy to go search, but I *think* GM spec's GL-5, which already has some friction modifiers in it AFAIK. None called for that I've seen in manuals. It would NOT be surprising if the lube specs have changed since the introduction of the gov-lock.

I thought posi lube was for cone type diffs ?
All the Gov Loc's I have seen have had metal friction discs , and worked fine with just regular ol lube ( until they let go LOL ) .

Not just cone type, Eaton (and others) make/GM uses a flat clutch style as well. Anything spring loaded. Since the gov-lock isn't "preloaded" like the spring type posi-diffs (which bind the axles together at all times) it doesn't need anything to prevent clutch chatter when you corner.
