I agree with you

'lunch box locker' isn't cable or electric. a 'lunch box locker' is an automatic locker that replaces the spider and side gears in the factory open rear differential carrier. if you are looking at an OX, cable or electric, you are looking at a a full case selectable locker, that will replace the current open or factory limit slip differential. the full case locker will require having the backlash reset, which normally means a trip to a mechanic with knowledge of setting up differentials.

cranbiz Where do you live, is it a daily driver or primarily a trail rig. What type of trails do you run?

Personally I like selectable lockers. I run ARB's in mine.

A lot of people like the Truetrac for an auto locker. The OX locker is nice. I believe they have ironed out the issues that plagued it in it's early life. The nice thing about them is if the actuator fails, you can use a manual override to get off the trail.

I would not put an auto locker in the front if you live in areas that get winter weather and I also wouldn't put an auto locker in a Dana 30.

How much ownership time do you have with a Detroit Locker? There are lots of things we install onto our Jeeps that can be noticed but that doesn't necessarily mean it's a bad thing or unliveable. I happily drove my daily driver TJ for years with a Detroit Locker in its rear axle.

Look at the Rubicon markup. Part of that is for lockers. When so many jeeps never leave the pavement give people options.

cranbiz Well, Jerry, I know they are the same vendor. It was not an install issue.

Anyways, I had 2 choices, reinstall the spider gears or install something the shop actually had available. The shop wasn't going to wait 6-8 days or more to wait for Powertrax to make a decision.
Sure, I could install a replacement locker but that would need to wait until the new gears are broken in and I replace the break in fluid.If money wasn't an option, then I could have gone a lot of ways, one of then just buying and overnighting another locker but alas, money WAS an option.

I got to say, looking at where the locker failed, does make me wonder if it could be a continued issue down the road.

Jerry Bransford You simply got a defective No-Slip which is highly unusual, I ran one hard for years without problem. That'd be a step backwards going with the cheaper Lockrite. Same manufacturer for both lockers you know right?

And keep in mind that even the very best made products aren't always 100% problem free. Odds are you wouldn't have any issues with the replacement. Just make sure it is properly installed. Who knows, maybe the first one was not.
