So, I've read posts and looked at my haynes manual and none of the instructions mentions removing the half-shaft (front drive shaft) to access the castle nut for the upper ball joint. But once I got out in the snowy driveway, took the wheel off and took a peak, i see no way to get that nut off without removing the half-shaft. Am I right or am I missing a trick for accessing that castle nut without removing the half-shaft?
