Wabco 1200 air dryer cartridge question
Does anyone know for sure(without guessing or just personal opinion) If a Wabco 1200 series air dryer cartridge goes bad based on time but not mileage?? 29000 miles but 10 years old; never if hardly...

While no one can tell you for sure if YOUR cartridge needs replacing or not, I can tell you that my owners manual states every 2 to 3 years (no mileage).
