Eaton True trac ?
Has anyone put an eaton true trac in their excursion ? I have an open diff in the rear now. I tow a 8,000 lb camper and it spins a lot in the dirt/mud in the campgrounds. I have to use the 4wd way more then I think I should.
I am thinking about the true trac because it doesn't have any clutches or parts that wear out. I plan on keeping it for a long time so I didn't want to have to worry about rebuilding the clutch discs later down the road.
I use it on the street a lot too, but not daily. So I thought a detroit locker was a little over kill.

After I burned up the rear diff iin my Lightning, I replaced it with a Detroit True-Trac rear diff. I love it. No more clutches to replace, ever.
I've read a few posts in the diesel forum where guys have installed a True-Trac in the front and rear diff of their trucks. From what I've read, it's all smiles for them after the install too.
If the differentials in either my Excursion or F250 ever go out, I'll replace them with a True-Trac too, without hesitation.

I really want a Gen 2 Lightning more then anything. Unless Ford ever gets off their butt and makes a Gen 3 Lightning. I almost bought a Gen 2 when I bought my excursion. I went with the Ex because I tow a lot.
besides that the true trac sounds like a winner

LOL!
Yeah, the True-Trac really performs perfectly at the 1/4 mile track, the autocross track, and in daily driving. Other than doing what it's supposed to do, I couldn't tell a difference between it and the OEM diff with clutches.

Even if they perform the same or even if the stock was better(which its not) there is little difference in price. I figure the difference in price is worth not having to rebuild the clutches later.
The guys with them front and rear should be able to go through anything.

You can Google it too to get more info. Detroit TrueTrac diffs are a pretty well known upgrade in the performance world.
Hope that helps.

Yes
remove diff cover
remove axle shafts
remove diff from housing
remove ring gear from stock diff
install ring gear on true-trac
install true-trac
set up backlash with dial indicator and shims
replace diff cover and fill with fluid
its pretty much the same thing you would do to swap out ring and pinions, if you are planning on swapping out your rear gears that would be the perfect time to add the true-trac.
If you stock diff has a lot of miles on it, it might not be working that well anymore. the stock t-lok LS diff has clutches that wear out with time and the true-trac would be a great replacement

Is there anywhere on the net I can get pics of how to remove the axle shafts and how to set up the backlash with a dial indicator and shims?
