I just bought my first 4x4; a 71 CST K5 (no idea what any of that means). I LOVE this truck. One problem. At about 50 mph & up she likes to "wander" from time to time. I replaced the draglink and centerlink tie rod ends, upper and lower ball joints, sleeves, etc. She's still wandering (but not as bad). I'm going to put on a set of shocks this weekend and see if it helps. I have looked for cracks in the frame, but haven't found anything. Any suggestions/tips are GREATLY appreciated.
