Front end noise

[HUMTECH]

Without actually hearing the noise its a little tough, but have seen many range shift forks break causing similar issues. When the fork is broken or excessivly worn due to the plastic fork tips falling off the transfer case wont complete its shift. Almost sounds like it may be stating partially engaged into 4hi lock when its supposed to be in awd mode. But if its only on a left turn its unlikely but may be worth mentioning. By actuator do they mean encoder motor on the t-case? cause the h-2 does not have a front diff actuator as it is all wheel drive and the the front diff is always engaged.
