Hi all.
I have an Express AWD that sometimes doesn't seem to get any power to the front axle. I have seen it put power to the front on occasion but have also had the rear spinning with no activity up front at all, it seems intermittent. This happens at a dead stop say when the truck is dragging it's belly in snow. I understand how the viscous coupling is supposed to work (different axle speeds warm and solidify silicone in the TC which tries to link the axles together ) , which apparently takes some time. But what if the truck is dead cold , say your snow plowed into a parking lot, like the last time the front axle did nothing . I spun the rear for a half dozen 5+ second attempts but the front never budged . Is that because the TC is cold ? I then backed up and slowly drove straight through. It seems as though it was using the front with a bit of forward motion but if it's standing still it is very hesitant to power the front .
It feels unstoppable when it's rolling but once the rear loses traction it seems to be a 2wd at least for a while.
I have full on snow tires on it but do not have the "G80" locker.
I know it's not a true 4x4, I have those also, but I also know it's supposed to put power to the front with a spinning rear in a reasonable period of time. Any thoughts ? Thanks !
