Noticed when I'm in 4hi with hubs in the "auto" position, they unlock when I come to an extended stoplight. When I start out, just the rears spin and then engage after I left off the pedal.
Is this normal? They are vacuum actuated right? Could I have a leak or just not pulling enough vac at idle?
Considering it's been snowing just about everyday since November, I switched to the locked position, but the autolock is helpful when going from clean to unclean roads so I'd like to figure this out.
Thanks in advance.
