I looked at a used minivan today from a dealership and it seems in good shape, but the Carfax report says that it recently had its front driveshaft replaced. It is a 2012 model with only 48000 miles.
Is this unusual? It seems odd to have to replace a front drive shaft (I've owned several cars over the last 21 years and never had to do so). Should I treat this as a red flag and pass it up?
