1. How much play should there be in the rear axle bearing?
I pulled the axles to get my third member out and there is play in the axle bearing when I wiggle the "brake plate" with it out, but when it is bolted up, there is no play at all when wiggling the tires. All four axles I have are the same amount of play when out of the housing

2. Is it bad if the rear output shaft of the transfer case has a tiny bit of play in it?
I can just barely detect a slight click when I push it up and down from under the truck.

3. How "tight" should the third member be when you spin it by hand?
The 4:10 third that came out of my truck has 112K on it, and is tight with no play, but I can spin it fast by hand and it will continue to spin a half to a full revolution when I let it go.
The 4:30 rear e-locker has much more "drag" and will stop instantly when I let it go. It feels smooth, just more drag.

4. One extra question. Do you guys use the Elocker gaskets, or just RTV only? "and what color RTV please"

thank you

When i replaced the rear wheel bearings in my 86 4Runner, the original bearings were so bad that i could wiggle them side to side almost a 1/4 of an inch. The new bearings made a huge diference. Im not sure on the rest of your questions though.
