I am running a Hydrotraxx and I have a set of plastic Tru Trax. They work great, but I seem to burn out my front bearings. I have now replaced all the bearings from original on all 6 wheels, but wondering if I should replace the tracks. One track has some wobble in it when running and a few of the side guides are broken off about half way down. No wobble in wheels when running without tracks. Any thoughts on if I should replace the tracks?
