ok had my Ultrex for 3 years perfect timing for something to go wrong .Last trip out i noticed a noise when i turned the TM under power like a clicking sound but only when i was turning , i could turn without power no clicking When i got home i deployed the TM to check it out noticed play in the steering head and figured i was time to swop it out 300 bucks gets you a new one and it does not look a big job but i like to reference projects like this on Youtube but guess what there is nothing on youtube about changing out the steering head
