I've been slowly rebuilding my front end drive train since last August when I had an unfortunate incident on a gravel road. I won't go into that in detail here, but one of the results was a blown front differential. A few months ago I was made aware of Harrop's option for the FJC through @wardharris at Cruiser Brothers and Harrop - Eaton ELockers | Toyota Differential Lockers | 4x4
I will detail the install here which was self-performed under the guidance of my friends at ACC Garage (@ACC Toyota). Because of the nature of the failed front diff, I could still daily drive it without adverse effects to the rest of the drivability of the truck. So I purchased an entire front diff assembly (stock gears) from a junk yard in order to maintain my daily drive duties and still work on the front locker install on the weekends.
Step one was to clean it up and get the replacement parts ordered. I got my 4.56 gears and install kit from Nitro and Ward was having the e-locker carrier shipped from their warehouse on the west coast.
Step two was to disassemble and remove the stock ring gear, pinion gears and all bearings & races from the clamshell housing. Then remove the stub shaft from the stock carrier using a slide hammer.
