Detriot True Trac or Lock Right in Front Diff??
 
Okay, so I bought a front diff off of Craigslist with a Lock Right Locker to replace the front diff that broke the axle shaft in the one I got with a Detroit True Trac inside it. SO, do I just put in the diff with the Lock Right Locker and call it good, or take the Detroit True Trac out of my old front diff and put it in this replacement diff??? Thoughts, opinions, advice???
Thanks,
CJ

For numerous reasons, I would not use any auto locking diff up front in any rig. I love my lock rights in the rear, but they do not belong up front IMHO.

Wouldn't an auto locking diff up front lock up anytime you turned hard and stepped on the gas? Bad things would happen, no?

Yes, they do. Seen lots of bad things happen with non-selectable lockers up front on numerous rigs. And even with power steering, it can be hard as heck to turn on slickrock, as in, really, really hard. Belt-squealing hard. Auto lockers (Aussie, Lock Right and Detroit) belong in the rear, not the front.

And CJ did shear the short side drive stub in his diff... Makes more sense if he had a Tru Trac in it.

A Tru Trac doesn't have springs or plates, just gears right? So you need to apply the brake and the gas to get it to lock/engage?

Are you saying that a Tru Trac is more enclined to break axle shafts than a Lockrite?

It's better than an auto locker, but they are not fully transparent like an open diff.

My $0.02 is that selectable lockers are the only thing safe for front diffs on snowy roads. That's a personal thing, some people are comfortable with limited slips.

I decided to sell my Air Lockers because in the front especially it took up quite a bit of volume in the housing and didn't leave much room for lube (less than a quart IIRC). I don't do enough rock crawling to see the benefit of a front locker but do spend a lot of time in 4WD high and in 2WD with hubs locked.
