4wd low

took them apart, it seems that the right hand side one had the spring broken took it to an engineering shop and he fixed it, it is working properly now. Now I found an other issue, there is an annoying noise coming from the rear, it's like a high frequency hum, it is also present when the gear is in neutral ,checked the wheel bearings and breaks, but it seems it is coming from the diff or shaft.
