Before changing front axle gear lube...

[jmeehan]

I just drained my front axle gear lube, and while wiping out the bottom of the housing I noticed the lube in the little trough at the bottom was much dirtier then what drained out. So I'm thinking it would have been a good idea to drive in four wheel drive for a couple miles to mix that junk in with what drains easily.

Thought I'd pass this along.

No need. Your front end diff is turning whether it's engaged or not.

Hmmm, for some reason I thought that with the pass. side axle uncoupled the diff wouldn't be turning.



Nope, I thought about this some more. Your front diff may or may not turn. If the spiders can rotate freely, and you have a front axle disconnect (pre '02) the ring gear and diff carrier should remain stationary while the spiders all whirl around transfering the drivers side rotation to the pass. side.
