1st setup was with a different gearset that turned out to have way too much runout. Sent them back to Richmond and they sent me a new set.
2nd setup was .029 shim/.008 backlash... With that setup, it had the correct pinion depth... Severe whine...
3rd setup was .020shim with .008 bl. Less whine but still not acceptible..
That picture is with a .026 shim and .008 backlash..
All of the setups have looked similar to that pattern. Like they all looked acceptible to me. Moving pinion in and out doesn't seem move the pattern around as much as I think it should. The gears are marked with 1.031 pinion depth and .008 backlash..
I expect a little whine since their aftermarket gears but what I'm getting isn't even acceptible..
Whats really confusing to me is that I've done quite a few gm rears, 7.5s,8.5s and 14bolts... And 0 issues... The ford 9 is supposed to be the easiest lol..
