A-Premium Power Steering Pump, with Reservoir, Compatible with Jeep Grand Cherokee 2001-2004 & Dodge Viper 2003-2006, Ram 1500 2004-2006, 4.7L 8.3L, Replace # 73329105, 52089300AA

Replaced a whiney and complaining OEM pump. 1000mi so far. 2004 Grand Cherokee, 4.7-N. Save yourself the hassle of pulling the pulley. A new Dorman pulley (Dorman 300-310) is only $12. I used a 3/8-16 bolt with a nut, socket, and a couple of washers to press the new pulley on. Was a tight press, but not difficult. New pump runs silent after I purged the air bubbles. I never realized how tight my steering was until I replaced the pump. Parking lots are a dream now. Hydraulic fan now runs on high when called for, and coolant temps dropped 7f.Tech-tip - if replacing a Jeep WJ PS pump, and you have the hydraulic fan, be sure and compare the high pressure orifice on your new pump to the old pump. Most new pumps have too small an orifice and you will starve the system and burn your new pump in a matter of months. They are not designed to run your steering AND hydraulic cooling fan. In lieu of swapping them on mine, I just removed the new one and drilled it out to match the factory size. If you remove to swap or drill, be careful removing - there is a spring behind that is DYING to fly around your shop! You will also have to remove to reservoir to get the orifice out.....

La obtuve hace tres meses y trabaja perfecto, tengo un wj 4.7 2002, la entrada de aceite es pequeña y pensé que tendría problemas , pero funciona muy bien .

Easy to install and functioned for bit over a year running in Grand Cherokee 4.7L with hydro fan, though it made noise from day one. I dismissed this as a noisy pump even though I spent 3 hrs purging air turning wheel lock2lock and adding fluid. Still, ~3k miles in this pump seized on me today, snapping the pulley and threw a belt. Motor only has 6k miles on a blueprinted 4.7...luckily I caught this in time and bought a 5" shorter belt to bypass and get home (# 815K6).

I was actually about to give up and return this pump after buying several fittings that did not work to conver it for use ony jeep xj 4.0.Turns out you just have to swap the high pressure fitting from the old pump to the new pump. I had to remove the pump/pulley to actually take it off. You'll need a 26mm to take off the fitting that comes with this pump.But once I got that headache sorted this actually does have more output than my stock pump andakes low mph steering much easier. I will update in 6months Incase it starts to leak but so far so good!

Customer car, no complaints or leaks or repairs, so it works

The pump looked great. It was new and came as expected however once installed it whined like no tomorrow. I had to replace it with a different one since it didn't work.Update: Turns out I had a problem with one of the lines to the pump. After fixing the line, the pump works as expected. I'm very satisfied with it.

Do yourself a favor and spend the $12 for a new pulley. A socket, bolt, and impact will press it on.

This pump actually went on my 1997 XJ and was direct boltin. I plugged up the 3/8th fitting and ran an AN6 fitting to convert the output of my steering box to 1/2 return. No whining and it turns 33's like butter with no whine, it's a nice feeling to have the front differential locked and it the steering still feels unlabored.Thanks!
