2001 Nissan Sentra

I have an 01 Sentra, 2 cylinder engine with 70,500 miles. The cover of my driveshaft was damaged, not exactly sure how. It looks like I ran over something. The cover is bent pretty bad and is hanging very loosely from under the front of my car.

My question is will this likely be a costly repair? Any help you could provide is appreciated. Thanks.

It's a four cylinder.

Are you talking about the boot that covers each end of the shaft?

Best bet is a reman half shaft, couple hundred dollars or so.
