Hey guys i accidently unscrewed the screw that you use to change the gears faster or slower just wondering how i can put it back to factory settings and also when i opened my dif casing i found a small spring and what looks to be a ball bearing im not sure what their for!! Does anybody no? Thanks

you need to find the hole where that screw goes, that small steel ball goes in 1st, then the spring and the screw goes last. turn it in about 3 to 4 turns and adjust from there.

Thanks so much and for also replyin so quikly
