When I was setting up the gears I got the coast side perfectly, at least it looked like to me. The pattern was centered on the gear and had a nice symmetrical oval shape, BUT the drive side looked biased towards the inner portion of the ring. I didn't quite know how to interpret it so I decided to center the drive side and the the coast fall where it may. Input?

And with some gear sets no matter what you go you are not going to get a nice center oval pattern. The newer 2 cut gears are a little different also.
The point is to get it as ideal as you can with the set you are working with. If it is going in a SUV, Van or station wagon I get real picky with the brand of gear and the final pattern. That passenger compartment over the axle is a damn amplifier.

Should I get the new pinion nut too, or the one I'm using will be okay?

Again for a few dollers get another nut if they have one in stock.

Excellent job by the way! The coast side is more important on used gears as stated before. Don't worry so much about the heel and toe position of your pattern versus the flank and face (inner and outer edge of the gear). It is very difficult and sometimes near to impossible to get a perfect battern. You want the pattern nicely centered on the gear and if it's a little biased to the heel or toe that's OK. With 3.42s your current position should be just fine. Make sure your carrier preload is good and solid, err on the side of too tight if anything so the total preload should be (for new bearings) 32 - 55.
I like your tenacity in trying to do it right - good job!

Just like always - no one has an idea what is a crush sleeve 
Ordered solid spacer from ratech
Shut - maybe I'll finish by the next weekend
BTW is there any way to mesure carrier preload?
Thanks guys

For example, I get the carrier in snug and get two .0065 shims and add one on each side. Its a real PITA to get them in but the "lock" clutch pack has some real thick flanges so messing up the shims themselves isn't an issue. I even bought a tool for it to spread the load over the entire shim pack when I hammer it in with a dead blow hammer.

I like to zero endplay plus .008 or so.

What post are you refering to? Are you sure I was not refering to a backlash setting?
As far as adding .010-.012, I really don't like them that tight. No more than about .008 usually is fine.

Also the only thing you have to watch for on some of the selectable interlocking shim packs is sometimes the thickness varies alot

Is this the .010-.012 figure you are talking about? If so I was talking about the shim thicknesses that are available in the kit not the total preload or what to add to the shim pack.

Is that would be okay if my drive side pattern is centered on the gear, even a bet on a left side?
