Make or buy a case spreader so you can put some more shims in there. You want the carrier to be TIGHT in there (as in tap it in with a rubber mallet tight). Dont set the CARRIER bearing pre-load too tight in your set up stages as it's a PITA to remove the carrier then. When you get your final pattern with your final backlash setting, add exact thicknesses of shims to both sides to tighten the pre-load up. If you do make a case spreader, DO NOT open the case more than 0.020" as you can tweak the housing (especially on an aluminum case like the D35's)
