My bro-in-law had issues with the piece that mounts on the driver's side firewall basically shorting out. Water would run on it from the cowl area and get into the electroncs. I believe his is an '04.

yeah its a 150. there not like a normal locking hub its an internal vacum operated (expensive)pos. looks like a unit bearing in design but has a vacum opererated cog ring inside. dont know if that started in 04 since there was a body change but i know my dad wasnt impressed when his 4x4 was only 4x2
