Adam----that pic you have above my post is excessively deep.....remove some shim from the pinion. My best guess is take 5~7 thousandths off the pinion.
PS---I saw the pic you posted last night over on Newbie General and that one was way too shallow....that one needed more pinion shim. Your patterns are easier to read now that you have some resistance when painting. Let us know what pinion shim values you are using to get these patterns. Thanks.
Adam----what value of pinion shim did you use here and what value on the other pic in Newbie General?
especially if you are running something like a detroit, I would go for as little backlash as the specs allow. You get so much slop out of the detroit you might as well make the gears tight as possible so there is slightly less beating and banging on the poor gears
brought it in .003, then .006 and here's where I'm at. Looks more centered to me. backlash is now .011. gearman did you mean FMS aftermarket gears or gears for fords in general. these are yukons if that matters. here are the newest pics:
ya Beezil...I was thinkin the same about young gavan.
Adam----you feel good that there is some good carrier bearing tension there? Putting the carrier back in the housing it went in tight....maybe had to beat it with a rubber hammer? I ask because I see a difference between the coast and drive side....the coast (first pic) looks good....but the drive looks a little shallow. Maybe re-paint the drive if you could. I am thinkin that the ring gear is moving around a couple thousanths....but if carrier pre-load is good then never mind.
Those are Yukon.....do the see US GEAR or the shield with a G in it on them?
AND it looks like the drive side would like to see even less backlash......be nice to bring it closer to the "inside"
