Replacement Passenger Side Drive Axle

I recently purched a Type S and the passenger side drive axle is going bad because it is an aftermarket part. Is it worth the extra amount to replace it with an OEM axle or is it OK to replace it with an aftermarket axle? What good aftermarket axles are there for a Type S? The car only has 46,000 miles on it. Thanks for the advice.

Get a "new" axle not a reman. We have good luck with Napa's new axles. I'm not sure how much more it is from the dealer but I know they can be a lot more.
