This came from Amazon for ~$192 (free sh), which is about $100 less than the best local price, and $300 less than NAPA or the dealership. I was a little annoyed to receive a damaged box inside a Pizza Hut box.

But the part inside appeared to be correct & undamaged.

I heard this clip was going to be a bear. I considered dropping the column for better access, but that just looked like more work.

Using 2 long Craftsman picks, I was able to release the clip. I raised the brake switch off the rod & used it to push the clip off the pin.

I might have spent 5 minutes removing this clip, including finding the tools.

With the foam pad pulled down to expose the nuts, I could see that the booster was also leaking inside, though not nearly as severely.

I marked the lines & ports to be sure, but the lines won't fit or reach to the wrong ports. The keystone clamp on the return hose won't be reused.

This is the easiest way to open a keystone clamp: jam a flathead in and twist it every way.

When the clamp loosens, it can be rotated for easier access.

With the loop open this much, the hose can be removed easily.

If I needed to reuse the clamp, it's easy to re-crimp it with end-cutting pliers. To make sure it tightens, jam the same flathead back inside before crimping, to keep the top of the keystone from collapsing. But I'm adding a common screw clamp instead.

The PS feed port uses a 16mm inverted flare nut; the supply port is 18mm.

Now it's ready to come out.

The nuts inside aren't easy to access, but I got to 3 with this extension, a wobble, and a deep 15mm.

For the top L nut, I added a u-joint because I don't have another wobble.

WithOUT disconnecting any brake lines, I pulled the master cylinder off and out of the way.

The old booster comes up & out.

The reman didn't include it, so I had to transfer the spider, spring, pushrod, & plastic washer from the old unit.

I finished, filled, & bled the system in less than 1 hour total.

To protect the new hydroboost, and everything else in the power steering system, I added a Magnefine 3/8" filter by disconnecting the line at the cooler return (silver keystone clamp), pulling it back through the core support, and running a new Gates line to the top of the fan shroud. The only new connection that's not visible under the hood is the one on the cooler outlet.

. .

Since I already had all the tools out for the PS filter, I cut the swage collar off the leaking transmission cooler line near the harmonic balancer, and added a filter to it, too. If it hadn't already been weeping there, I'd have cut the swage behind the bumper (top L of the photo) since it's easier to get at. But this way, all my connections are visible from the top.

ISSUE: Contamination from prior transmission concerns or excess wear may be trapped in the transmission fluid cooling system. This debris must be removed by properly cleaning the transmission cooling system. After cleaning, some contamination may still remain. The remaining contamination may be reintroduced into the fluid cooling system of a repaired/replaced transmission causing premature or repeat failures.

ACTION: After every overhaul or transmission exchange, clean, flush and backflush the transmission fluid cooling system which includes: fluid cooler, auxiliary cooler, cooler lines, and Cooler Bypass Valve (CBV), if equipped. Perform the cooler flow test to ensure proper transmission fluid flow volume on the transmission return line through the cooling system. Once proper fluid flow volume is verified install the Transmission Fluid In-Line Filter Kit (XC3Z-7B155-AA) in the fluid cooler return line (transmission fluid flow coming out of the fluid cooler going into the transmission). Refer to the following Service Procedure for details.

SERVICE PROCEDURE

NOTE: THIS IN-LINE TRANSMISSION FLUID FILTER KIT CAN BE INSTALLED ON ALL TRANSMISSIONS WITH 8mm (5/16") AND 9.5mm (3/8") TRANSMISSION FLUID COOLER LINES.

NOTE: THIS IN-LINE TRANSMISSION FLUID FILTER KIT WILL ALSO BE SUPPLIED WITH ALL E4OD/4R100 AND OTHER FORD QUALITY REMANUFACTURED (FQR) TRANSMISSIONS. AFTER ANY OVERHAUL OR TRANSMISSION EXCHANGE PRIOR TO CONNECTING THE TRANSMISSION FLUID COOLING SYSTEM TO THE TRANSMISSION, FOLLOW THE STEPS BELOW.

Clean, flush and backflush transmission fluid cooling system.

NOTE: VEHICLES EQUIPPED WITH STAND-ALONE OIL-TO-AIR (OTA) FLUID COOLERS CANNOT BE PROPERLY FLUSHED. ADDITIONALLY, 1998-2001 CROWN VICTORIA/GRAND MARQUIS AND TOWN CAR HAVE OIL-TO-AIR (OTA) FLUID COOLERS EQUIPPED WITH A TERMINAL BY-PASS VALVE. FOR ALL VEHICLES EQUIPPED WITH STAND-ALONE OTA COOLERS, THE OTA COOLER MUST BE REPLACED ON EVERY OVERHAUL OR TRANSMISSION EXCHANGE. REFER TO THE APPROPRIATE SERVICE/WORKSHOP MANUAL FOR PROCEDURE.

Once the fluid cooling system has been cleaned, flushed and backflushed, connect the cooler lines and perform the transmission fluid flow test to ensure proper fluid flow. Refer to the appropriate Service/Workshop Manual for procedure. If proper fluid flow volume is not obtained, refer to appropriate Service/Workshop Manual for repair procedure. The transmission fluid coolers, auxiliary cooler, OTA, cooler lines, CBV (if equipped), transmission fluid pump or internal filter may be restricted or damaged and require replacement.
CAUTION: FAILURE TO FOLLOW THE KIT INSTRUCTIONS MAY CAUSE INTERNAL TRANSMISSION ASSEMBLY DAMAGE AND REPEAT REPAIRS.
Only after proper transmission fluid flow volume is present, install the Transmission Fluid In-Line Filter Kit (XC3Z-7B155-AA). Follow the instructions provided with the kit.

Once the filter is installed:
With the transmission fluid return line disconnected from the transmission, verify fluid flow through the filter. Once the fluid flow in-and-out of the filter is verified, connect the transmission fluid return line to the transmission. Check and adjust proper transmission fluid level to normal operating range at normal operating temperature and check for leaks, kinks and chafe points (refer to the "Do's and Don'ts" chart in the kit instructions).

NOTE: THE FILTER INCLUDED IN THIS KIT WILL ALSO BE AVAILABLE AS A SEPARATE PART (XC3Z-7B155-BA). IT IS RECOMMENDED THAT THIS IN-LINE FILTER BE CHANGED EVERY 48,000 KILOMETERS (30,000 MILES).
