Replace drive shaft & manifold

This all depends on what you need, want and can afford. A Jeep that is nearly 20 years old would be best replaced however these repairs are nothing out of line for a vehicle with 140k miles.

I think so. There comes a time when you're just throwing good money after bad. Every time you turn around it's something else! The vehicle spends more time in the shop than on the road! At that point it's cheaper in the long run to get a newer vehicle. Hope that helps! Jim
