It's that CV joint at the transfer case that kills the drive shaft every time, isn't it? Or that fact that you didn't have the proper drive line angle on your lifted Jeep. Or the slipboot ripped when you were on the Dusy Ershim Trail. Let's face it, there are so many things that could go wrong with the drive shaft that require it to be replaced. But one thing that guarantees you will have problems is installing a low quality drive shaft from the get-go. And that's why you are here on 4WD, where every brand of drive shaft on offer is from a well-known, high quality manufacturer such as Rubicon Express, G2 Axle & Gear and Dana Spicer.
