I tried searching but no real luck.

In the catalogs (4wd and Q-tech) there is a footnote that when installing some of the lockers (Detroit Locker, etc) that a hub conversion for 87-95 YJ's is required.

Really? Why? Would that be required on an Aussie locker?

What do you guys do?

Thanks,

The 87 to 95s come with a split axle that is disconnected via a movable splined ring.
This means that one side of the front differential is being turned by the tire whenever the vehicle is in motion. Some manufactures do not recommend their differentials for installation as this means increased wear. Installation of a hub conversion eliminates the constant turning of the front differential improving mileage and reducing wear.

What do you guys do?

I replace the 2 piece axle with one with lockout hubs.
I did use an ARB in the front of an 87 YJ for several years without ill effects and no hub conversion. For warranty reasons I would follow the manufacturer's recommendations.
Enjoy!
