I have had my mrs4 for so long that i cant even remember if the hpi steel versions came with threaded screws or not......but i think they did, really cant remember.....Cool man cant wait to see some updated pics.
The screw goes in where the red arrow is pionting right. Well the screw went all the way through that piece and touched the inside part of the knuckles where the green arrow is pointing. So not being able to tighten it down all the way it left the wheel loose. So I had to snip the screw downn to get the ability to tighten the screw in.
And one more note, the right side fitted in fine. it was just on the left where i had the problem.
are you sure that you used the right lenght screw for the other side....please make sure man....it shouldnt matter anyway just as long as you have it in there........did you use some loctite....if not you should the inner wheel just might fly off.
I dont have any screws at the bottom of my knuckles.......but it shouldnt matter now since you got the innerwheel on there....did you use loctite by any chance.......if not just apply a small drop on the screw.....i use blue, which is strong enough.
