Jeep cherokee XJ with WJ grand Cherokee power steering pump upgrade swap issues??

many people have reported various issues when swapping a 4.7 V8 grand cherokee power steering pump on a Jeep Xj Cherokee TJ wrangler or MJ Comanche. this video tests pump pressures on multiple pumps to explain mixed results people have reported with this swap. the wj pump is for high volume so no drilling should be required unless you are running additional items off the power steering pump. I ran a stock XJ pump and fitting with a 2003-2004 4.7 WJ pressure releaf valve. I the pump valve can be identified because the WJ will have a hydraulic cooling fan. i have not found a source for the valve other than the junkyard or to buy a WJ pump and remove the valve. if someone finds the valve elsewhere please post the link. 0:00 Intro 0:40 Stock WJ pump pressure test 1:39 Stock XJ pump pressure test 3:05 Jeep XJ pump with WJ pressure re-leaf valve installed. 5:00 Drill fitting on pump NOT Recommended 10:12 conclusion the facts 12:36 pump dissemble #jeepcomanche #jeep #jeepcherokee
