    Question What’s this sound? Day 4 of my new X Maxx

    Afternoon all.

    Had an X-Maxx for 4 days now and started to get a bit of a grinding noise from it when running.

    Here’s a video so you know what I mean....

    Can anyone help me out on what it could be?

    I have already updated the the carriers to the RPM carriers and up-rated bearing plus’s outer ABEC3 bearing and front bearings but don’t think it’s them as it’s only when accelerating.

    I have taken the cover off of the front of the motor and the motor pinion looks ok but the big gear off of that has a fair bit of play forward and backwards and a little up and down. Could it be this?

    The Maxx runs ok but just don’t want to explode a bearing or cog and cause more damage.

    If anyone can help out, that would great.
