I think it needs a little more pinion shim. You're getting a hard line at the bottom and a soft line out towards the tooth edge but where I cant hardly make it out but it looks a little too close to the edge. The thicker pinion shim will move the gear mesh a little further in.
yes, way more. .0065 is almost zero lash. you may need to pull more than .002 out of the pinion to get the pattern and back lash you need. go down to .025 pinion shim and start there. it may be extreme but I bet it gets you pretty close with the correct backlash
This is 0.026 with 0.008 of lash. Couldn't find the right combo of shims to get 0.025. http://imgur.com/a/ytE1Z

I will try more if that pattern doesn't look okay.
Your looking pretty damn good. Your pattern is tailing off the inside ever so slightly. I think you need 1 or two thousands less under the pinion and play with backlash from there. Since you couldn't get .025, try .024. Your real close

Your coast with .024 I don't really like, but your drive side is pretty good with .026. Play with the back lash a little and see what it does. you may have to go back to .026 and play with backlash a little bit to real it in. You may have to settle for one or the other, some housings just don't line up great and make it tough to get an ideal pattern.
what are you using for marking compound? its smearing and I fear that its misleading a little bit.
This is the 8.8 in my car, try to get a good reading like this if possible, your compound is awfully 'wet'.
I'm using the stuff that came with the yukon overhaul kit that I bought. It should have thickened up sitting for the past day or so. I'll try 0.026 with 0.010 of backlash or so.

The Yukon stuff is good, that's what I use. It may have just been the picture. That's getting a lot better. your coast looks like it needs a touch more shim under the pinion. Your really close, your a very small adjustment away from getting it perfect.

So, try 0.027? Doesnt it look too far away from the root and too close to the face?
Before I changed the pinion shim instead of .010 B/L , move it to .007 or .008 and see what it looks like . This would move the pattern down some . May be all you need . I agree , you are close but does look a little shallow . If not better then I would add to the pinion shim .

I've already done 0.026 and 0.008 of lash. It wasn't ideal. I'll try 0.028.

x2, i agree. When your this close sometimes it can be reeled in with backlash adjustments. I always play with backlash before changing the pinion shim. but I think your coast is a little far off to be corrected with a backlash change but I could be wrong

.027 is pretty good. coast is much better and I like your drive even more. .028 should be good, drive is getting even better now but its moving away ever so slightly. go up and down with backlash and see what happens, you may need to try .028 under the pinion but if it messes with your drive to much you may have to stay with .027

I agree, Looks much better . I would try .008 b/l to see what it does . If it still looks pretty good I would run it . The b/l will open up some after it has run a while and breaks in .
Also could try a .028 shim with a . .008 to .009 b/l just to see what it does . Which ever looks the best , but I would have not problem with your last pattern .

That still looks pretty good . Not much better if at all . I would shoot for .008 to .009 b/l and button it up .
Just for giggles if you wanted to take the time and try a ..028 shim and see where it goes . If me I would have no problem running it as is with a .008 b/l .

I think I will go ahead and run it, I've had that thing in and out enough for the year. Are there any tricks to crush sleeves? I've got a mg725 that will have no problem with crushing it, but not sure on how to not over crush it.
Crush sleeves when you get close you have to move very very very slow when you get close . I have started using solid bushing now when I do a gear set . It has the shims so you can set preload and just torque the nut down . I have come to like that method better .
If you already have the crush sleeve just use it . If you have problems you may want to consider the solid bushing .
The only way for a crush sleeve is by hand with a cheater bar . If it is under the car on jack stands I use a piece of angle attached to 2 of the u join mounts with a v notch so the socket will fit and bungee it up to the bottom of the vehicle so it will push up on the bottom . Then I use a 1/2" breaker bar and push with my foot . No way you will do it by hand under the vehicle . Don't be surprised how hard it will be to move it . Just take your time . Hope this helps and good luck .
