So im new to on road, just built a tcx with a 17.5 tekin and love it! Today I was testing indoors on carpet which was the second day on the kit. Everything ran smooth and then out of nowhere my car was making a nasty vibration noise when the car was turning on moderate power. It was fine in a straight line, or turning on full power. I took it apart and inspected everything cvd pins, uprights, spindles, hinge pins, front gear, outdrives, and drive shafts and nothing helped. My first thought was a cvd pin was coming out but they were fine. Any suggestions on what it could be, or how to fix it? Thanks.
