Yeah I'm not sure if you'd go tighter or looser tho 1st thought was tighter (but not sure). I'm getting ready to do my 1st R&P as how hard can it be as there's only pinion depth (forward/backward) and backlash (in/out). I did add a sure grip to a 7&1/4 and months later it has a ton of backlash (no noise tho) and I merely duplicated the tightest backlash reading I got w the open before I opened it up which was kind of disheartening & dont think I forgot to tighten anything & it had the threaded side wheel locks in place so...
