Did you guys do just front and rear mounts or left and right?
R the top (not the plate that holds the spring) but the top plates in the front engine bay too tight. Mine where getting caught up on the tower somehow.. So I just loosen them some so they can turn easy and no more click bang.
As far as the grinding I would say the motor miss alignment and maybe putting too much on one axle.. (these r only suggestions) hope you guys figure it out.
