I may be scoping around for an AWD vehicle for a family member soon and will be looking at used vehicles in the $5000 range. I've always been hesitant on used AWD vehicles since it just seems like more parts that could break.
I'm noticing a lot of these modern AWD systems use clutch packs in their transfer cases (and sometimes in the differentials too) to shift power. My understanding is that these are wet clutches of which in theory the wear is minimal since it relies on hydrodynamic lubrication meaning there's no physical contact of the clutch plates. Is this typically true of all AWD systems, and how is the long term reliability on this? Is the fluid the only part that breaks down and needs servicing?
Would like to hear your thoughts and experiences on these AWD systems. Which manufacturers are known to be more reliable and which to stay away from?
