Edit: This started as a parts request but it has gotten somewhat "techy" so it was moved to a more appropriate section. I'm going to change this up a little bit, to include some things that may or may not be missing from all the great writeups. This is not going to be a writeup by any means, just a little added tech for those searching to do this.
I am putting an elocker in my '93 4runner:
Parts I needed:
elocker diff gasket (thanks MarcP)
2 111mm axle studs
2 8mm lock washers
2 8mm nuts (I got these at Marlin Elocker Parts.) You can also get them from NTP, I just went with Marlin due to already getting some other stuff from them.)
2 rear axle seals (I got the Special Rear Axle Seals from Marlin Crawler, so we'll see how they do. They were only a few cents more over the regulars.)
Drill and tap set? Need to find out exactly what size tap. I know it is 8mm but need to find out for sure the thread pitch.
Already, I have seen something that isn't covered in the writeups, and that is for those that have the ABS sensor in the top of the third member. You will lose ABS. We will see what works to make sure that the ABS light does not come on. Paddlenbike has promised to help me figure this one out once I get it all buttoned back up. The reason for this not being covered, is that most writeups are on 3rd gen 4runners which have ABS sensors at each wheel or are on older axles that don't have ABS.
