Looking for some suggestions here. Any advice would be appreciated. When I shift my 2003 6.0 PSD excursion into 4x4, I can hear a noise in the transfer case (sounds like it is engaged) but no power goes to the front wheels.
Thanks
Had the same problem with my 03 Excursion. Oil never ended up in the oil but was disappearing. Turned out that one of the heads was cracked and coolant was leaking into the cyclinder. Expensive fix.
Best of luck
