Hey all, This is my first build up just so you know, so If this is a stupid question please forgive me. So I just bought the HKS D1 replica Yokomo drift RC. And I just about finished the build up, I was putting on the tie rod on the ball stud. But with the slightest bump, it falls off. Is this normal or is the ball stud supposed to snap into the ball cap. Also I got the new drift tires with the single broad ring. But I can't get them on, it's just too tight. Can any one give me any tips to get the ring on. Thanks.
