Oh they break, there are some items that are for the most part are known to break on any vehicle when wheelin. Tie rod adjusters, T-bars on occasion, T-bar adjuster, CV joints, hubs and a few other things. When they break most plan ahead (the experienced wheelers) and bring replacements. For those that dont have X-tras, XOC members are real good about helping each other out.

THis is why you should wheel with folks with experience. There is alot to learn, and most enjoy teaching. Come out you wont leave mt handed.
