Hello HummerTech. Long time hummer fan and first time poster. My 2002 H1 transfer case will sometimes pop into neutral while driving at freeway speeds. It seems to happen after I have been offroad and I hav ebeen using the low lock and high lock settings. Then for the next few weeks I'll have occasianal issues when it makes a loud bang and pops into neutral. After a while it stops doing that. Any ideas?
