Front Diff Flush.

Front Diff Flush after axle service?

I am flushing the front diff after doing the axle service to clean out some of the moly and built up junk that has collected there for the last 150k. How long do you all think I should need to do this before draining and refilling with synth?

How hard are you on it?
Wheel 2 or 3 times a weekend?
Tow with it?
Daily driver?

If its your daily driver and you tow with it an wheel it, every 4th oil change ie 12,000 miles. If you get to trailer it possibly every 100-120 hours in the dirt, or once a year, if you don't spend that much time wheeling it.

Lex,

Unfortunately, for now, it is just my DD. We get up into the mountains once in a while, but not as much as I like. At least not for fun anyway.

I'm just trying to clean the inside of the axle a little before I put the synth fluid in. The old fluid was almost black when I drained it.

It will depend on how much birf soup you had going on. I'd buy a couple of gallons of the cheap Coastal gear lube. If it was pretty contaminated when you did the front axle service, drain after a few hundred miles, then a second time after 1500 miles or so, and then you should be pretty good... but let the oil tell you if it needs another flush.

Rookie2,

That's about what I thought. A few hundred miles and see what it looks like.

Thanks, Gene
