What should I expect for maintenance on a 06 OBW 2.5 non-turbo, manual tranny.  Cost and lifespan woudl be appreciated 
  
In particular: 
  
Clutch life  
Front and Rear brake Life 
Center diff (Viscous coupler) 
and rear diff (limited slip) 
and is Heat gaskets an issue on these vehicles 
  
Thanks
