My cousin drove for 25 miles at highway speed on dry pavement with his pickup in 4wd without noticing that it was in 4wd. Then it broke one of the front cv shafts. He put a new shaft in and within a couple of weeks it broke the same shaft again. What would be causing this? Is the differential locking up? I haven't looked at it yet. How difficult is it to get the front diff out on these pickups? TIA
