Have a 2004 lly 4x4. Have a abs light and a random brake light. Have 2 codes c0040 and c0055. Likely needs a front hub and rear vss in the t case. Put a rear speed sensor in...still randomly getting a brake light and c0055 still. In my last 04 the tcase was messed up and had a bad fork and would jump out of gear but this one doesn't. Just every once in a while the speedo gets a little shakey still. Can the front wheel bearing that's bad cause a confilt and make the c0055 light still come on or is my transfer case getting messed up slowly ?
