Locker Installation on F250SD

[Hocky54]

I have a 2007 6.0ltr F250 sd 4x4 without a locker in the rear, I would like to fit a detroit trutrack inplace of the standard diff. The truck has covered 72000km, do I need to replace all parts in the diff, or just the locker bearing,shims,bolts etc.

Any help would be appreciated.

Yes you should only need to replace the bearings, shims, bolts, etc. The gears should be reuseable. Of course, since you are replacing the locker bearings, I would also replace the pinion bearings and seals to.

The only thing that you might have an issue with is if you reuse the ring and pinion, if they are not set up exactly like they were they might sing a little. Not saying they will but every now and then it happens.

That's a good point Lee. Perhaps it may be a good idea to get a new set of gears. I still think though I would try to reuse them but that's just me being cheap.

I went that way, when I set up my ARB Locker and they sang thats why I mentioned it. I tore it back down and use new gears and was all set. little noises really bug me! I guess it the ADD kickin in! LOL

The gears will sing if they are not set up correctly whether they're new or used. Set them up right and they are fine. Reusing the gears is no different than pulling the diff to rebuild the clutches and putting it back in with the same gears.

+1 for this.

if you are running 35+ tires you might want to think about re-gearing at this time, since you are already in there.

ahh... the eternal debate about whether to regear...ever read that story "if you give a mouse a cookie?"...about how if you give a mouse a cookie he'll want a glass of milk, then a story and blah blah blah...gears have always been that way for me. "I'll just stick a detroit in the rear...well since I'll be in there I'll do it right with new bearings and seals, might as well regear...of course then that means the front too...and bearing kit for the front"... what was a relatively cheap (only by comparrison) upgrade, has now turned well into at least a 1500 dollar ordeal, plus a couple fluid changes for breakin, not counting whatever is to be done about the speedo...the things we do for performance. It's just money right?

Just my two cents, been down that road a lot. Good luck.

Also too, I have heard, and it's only been heresay, no personal experiance, but I've heard the truetracs don't hold up as well to bigger power, and bigger tires as well. I do know they don't function with a wheel off the ground. I got a truetrac in a 69 mustang with an 8.8, and it works flawlessly, but that's almost always on dry pavement, and with both wheels on the ground...both rear wheels that is. Food for thought depending on how you intend to use it. I'd vote straight detroit locker...had them in a few different trucks, the newer ones are much quieter than they used to be...and smoother. make that three cents.

Ah yes, the "while I'm at it" syndrome. If anybody finds a cure please let me know. I've had it for years and can't seem to shake it.
