how often should be replacing my diff. fluids. i only bash. id like to say i get to drive everyday but i dont. more like 1 or 2 times a week. for 3 to 5 hours at a time. thanx, clay unruh

I like to reaplce mine after about every gallon, but every 2 gallons is fine.

Well Clay, you can basically bash the diffs with the same diff oil indefinitely so long as the oild does not seep out. Sooner or later though, you will have to break the diff open for maintenance, like replaceing the internal spiders, shimming them because they wear and are beginning to suffer from lash in between the teeth, and of course, they begin to leak.

thanx ill keep that info in my head and tend to them as i see fit. thanx agian, clay unruh
