Well I'm saving up for a 4.5 lift and I do know you need an SYE for this and a CV driveshaft, But my question is do 99 Jeep XJ's already have the CV Driveshft? Because I heard they did have that option. And another question would I have to get a new rear driveshaft too?

 

The front shaft is a CV. The rear is the one that won't work. But a front shaft will work in the rear with an sye so just go grab a front one from the junkyard

 

Thanks man
