What was the shim in the pics in the previous post?

THe .026 looks way better. Might try going to .03 and checking if the coast side will move more to the center of the heel-toe.

Iīm not sure what the shim thickness was in the previous post but I think it was 0.037". Ok, iīm going to try out the 0.03 shim. Should the gears make noise with this setup? What should I prefer, a setup too close to the root or a setup close at the toe as this setup?

The .026 pattern looks pretty good. The coast being biased toward the toe is not great but would probably work out.

I'm going to assume that you are turning this with the pinion gear because the pattern is not clear with defined edges. I recommend sticking an axle in and use the axle to turn it several times in both directions to get a more clear pattern. Also be sure that the pinion bearing preload is set correctly every time.

The .026 pattern looks pretty good. The .030 pattern looks pretty good on the drive side, but the coast side is a little too much on the root. Go back to the .026 and make some adjustments to the backlash to see if the coast pattern will move toward the heel some. Use the axle to turn it.

ok, so I got a nice pattern so I began to install the pinion for the final time. I installed a new seal and a new crush sleeve but I got really worried when I started to screw the pinion nut. I was told that I should screw until I feel the crush sleeve crushes (it would rotate easier) and that it would take a lot of wrench torque until it crushes. So I started to screw the nut (really hard) but not until it crushed because the pinion got stuck (I couldnīt rotate the pinion). Is this normal and will the pressure release when it crushes?

The pinion should be loose the entire time until the rotational torque is correct. Also the numbers you posted seems low, usually the lower numbers are for used bearings(6-15 in lbs). Usually new bearings are 15-29 in lbs...

You should have to put around 300 foot pounds of torque on the pinion nut to get the crush spacer to crush. If the bearings got tight before that then you have a problem. The spacer may be used or it might have been a bad one that was made too short.

anybody knows how to do a proper assembly of the inner retainer of the drive shaft? should I heat the inner retainer so it shrinks or can I just press it on? And how important is it to have new gasket (at the brake backing plate)? because the axles I know have is in bad shape and is going to be replaced when I got new ones (about a mounth from now) and donīt want to spend to much money on something temporarily.
