Ok this one has me a little stumped/irritated. Got this one in to fix, has less than 1000mi on the gearset with metal in the oil. Explorer 8.8. The driver's side shims had pushed out into the axle, that was the metal. I've done tons of these with no issues and this one is a bastard. No matter what you do to this thing the pattern sucks. Its looks damn identical to this pattern at any pinion shim thickness using the correct 8-12 thou backlash. These are 4.10 ford racing gears using the .030 shim from under the factory 3.73 gearset. To me I would say the pinion is too close from the pattern but it looks just the same with a .015 shim. The coast side leaves a tiny line near the toe, not to mention if you roll the gears as if it were coasting you can hear noise. I've checked everything I can think of. And the fact of them being ford gears you can't use a pinion depth tool because the pinions aren't marked, if they were marked I would have just set it at that and put it back together.
