Powertrax no-slip locker exploded

Disregard, I zoomed into the picture.

I had set the bearing caps off to the side the way they came off.
The pictures don't show the other one, but there's a horizontal W and a vertical W on the housing. The caps have corresponding horizontal/vertical Ws.

Is it possible to measure the difference in carriers between the >3.73 and <3.54 ones?
I have a carrier that came with 3.55s that I could use, if it would work
 
Installed a powertrax no-slip in the front Dana 30 of my tj yesterday. Seemed a little slow to unlock, but I assumed the grease was still working it's way out.
Went to go somewhere this morning and this happened about a mile from my house. It had about 20 road miles on it from yesterday.
It felt like it wasn't onlocking, then when I turned off into a parking lot the front axle locked solid. I backed up a bit, then was able to make it back home.

The one in the rear(Dana 44) works flawlessly. Little weirdness around parking lots and leaving stop signs while turning, but otherwise invisible.

Wow! I put mine in about 2 weeks ago...got about 300 miles on it. Works flawless so far. Sorry to hear...maybe defective?
 
Powertrax says to go through the distributor for warranty and said they haven't seen any failures like this before. It blew up all 3 parts of the locker on the driver side, without damaging the axle. They didn't think it was installed incorrectly.

What are the chances of getting the other parts covered under some sort of warranty?
Of course they said that... ask them about heat treat records...

@whitrzac after 40 some years of fixing, chasing parts, and otherwise getting kicked in the nuts I have heard this line over and over. I must be the most unlucky SOB on earth!

Think of the keyword in that sentence: SEEN
(Hard to see when your head is in a bucket of sand)

Reminds me when I go into John Deere
JD: "those never fail"
Me: Mine did, you got any....
JD: checks computer....Oh! "I've got 11 of them in stock."
Me: Wow thats quite a stock for a part that never fails!

This page helped to verify that the carrier I bought was 3.73.


Replacement locker should be here tomorrow. I bought a new carrier/bearings but am going to reuse the ring/pinion. I plan on picking up a HP Dana 30 in the near future to build and swap over.

Powertrax and national drivetrain are both in chicago, but they had me ship the old one to grand prairie Texas.

New locker, same as old locker.

Something was definitely messed up with the first one. The old one would unlock midway through a turn and had some other weird issues, always in 2wd.

This one acts as I read about and expected. Completely invisible in 2wd on the road.
 
Probably not, I may call the later today to press for information and compensation.

If you see this rewriten and posted in every facebook group and forum, it probably didn't go as I hoped

You drove home on a busted locker, do you really think you're entitled to compensation? Not to mention this part in bold print in the manual:
REPLACEMENT OF DEFECTIVE PARTS, RETURNED AS STATED ABOVE, IS THE SOLE REMEDY FOR ANY PRODUCT DEFECTS UNDER ANY AND ALL POSSIBLE WARRANTIES

Like driving home on a flat tire and asking the tire company for a new rim. I guess people do it these days. I can just see the old-timer at Goodyear rolling his eyes as the lawyer tells him it's just easier to pay the guy off.
 
If you didn't understand shit had gone south when the front tires locked up I guess I shouldn't be too critical. It's just that some companies that make good stuff for my Jeep have gone out of business because of claims like this.

I had no idea what happened until I took it apart.

Even if the tires locking up didn't clue you in why does any of that matter? Powertrax says if their part is defective they don't cover anything but the part and the distributor already helped you out. It is the only section in the entire manual printed all caps and in bold. Again, why are you entitled to anything?
 
Who pissed in your Cheerios this morning?

If Powertrax and the distributor pay up, prices go up for all of us and you'd be the one making a mess of our Cheerios.

I'd say all this stuff to my buddies sitting around a campfire, they'd call me a sucker and we'd laugh it off. Doesn't come off that way on the internet - oh well.

Great you got it back together, I love mine and I'm sure you'll get some good use out of yours.
 
New locker, same as old locker... Broken.

Roughly 1500 miles. 2 days of wheeling
Did a mild trail(hills/gullies green trail) at flat nasty a couple weeks ago, left it in 2wd for most of it because of the tight turns, and 4x4 wasn't really needed except for a few of the hill climbs.(I was there for a different event, not to wheel)

Was at cliffs yesterday, all mud, no traction, and someone pointed out I only had 3wd near the end of the day. Pulled the diff cover to find the springs had collapsed keeping it from locking both wheels. Drove home and looked at it this morning.
Upon closer inspection, it has a hairline crack in one of the plates....

No more lunchbox lockers for me.

2 for 2?
I'd say that there is some other problem, somewhere...
Absolutely. I ran the No-Slip for years in my previous TJ with never a problem, and it held up fine with even some even extreme rock crawling trails occasionally in its repertoire.. It has too good of a reputation for a single owner's two breakages to be anything but an unrelated problem, perhaps an install error.
