I have changed the IWE actuator assembly and hub assemblies on three different occasions ( roughly 20,000 mile intervals ). I have had nothing but trouble with this it since it started occuring 2 years ago. What I understand from my dealership is that water etc. keeps getting into the IWE solenoid causing it to fail and only allowing the 4x4 to partially engage which then causes stripped hub assemblies? I am at a loss, I love my truck but have spent over $4000 on my 4x4 and I hardly ever use it? Is there a relocator bracket for the solenoid available or does anybody have any other ideas, it would be greatly appreciated? thx for your time RYAN
