Below are pictures of the emergency brake system components in a 2000
ford crown victoria police interceptor.
Here is the driver's side e-brake backing plate and brake shoes with
the axle removed

Leaving the caliper hanging by the flex hose like this is a bad service
technique that can cause flex hose failures later on

Not only has the axle shaft been removed from this side of the rear
axle assembly, but the wheel bearing and seal are also out.


Here is the other side of the car, this side does have the axle shaft
removed but the wheel bearing and seal are there.





Here's the other side of the car again


You do not normally have to remove the carrier to pull out the axle
shafts. But this car is having some repair work done to the
differential side gears.




Here's the e-brake backing plate

And the e-brake backing plate on the other side

Here are the axle shafts

This axle shaft has a little bit of wear where the bearing normally
rides

This axle shaft is in very good conidition in the wheel bearing area

Here are the rear brake rotors. These do not have cooling vanes like in
the 2003+ cars.

Here are the rotors from the back. Normally, the parking brake shoes
will ride inside the rotor hat.

Here's the carrier assembly from the rear axle





And a collection of various parts that had to be removed to pull out
the carrier and the pinion gear




Here's a new wheel bearing seal to install

The 2L1Z-4215-EA differential side gear kit. This one is intended for
"locker" carriers rather than "open" ones.




Here are the parts which you'd remove to pull out just the axles. To
pull the axles:
-remove the lock bolt
-slide out the locking shaft
-remove the antilock brake sensors
-push the axles inwards
-slide out the c-clips
-the axles will then slide out of the axle tubes


Here's the driveshaft

The bearing caps

An identification tag. The "3L55" stands for 3.55 locker.


Here are the differential side gears again

Here's another picture of the differential pumpkin with the carrier and
axles out


In this picture you can see where the watts linkage connacts to the
differential. You can also see the hole where the pinion gear would
normally be installed

The e-brake backing plate has scaly rust all over.

If you look closely, you can see a hole in the metal that isn't
supposed to be there too.



Below are some pictures that chevyguy on www.crownvic.net took during
insallation of a 3.55 locker rear axle assembly from a wrecked 2000
crown victoria police cruiser into hit 2001 civilian crownvic.
Here's the rear axle from the wrecked donor car at the boneyard. The
axle assembly had been sitting unused for a couple years outside
exposed to the elements, so the galvanized coating on the control arms
has worn away allowing the underlying metal to rust.


Here are the axles showing the area that the wheel bearings would
normally ride on



The e-brake backing plates on the junkyard rear axle assembly were bent
from rough handling at the salvage yard, so they were removed




chevyguy wanted to reuse his existing e-brake backing plates, so he
left the e-brake cables attached





Here are the messed up junkyard e-brake backing plate assemblies.
Damaged e-brake backing plates seem to be a common issue at the salvage
yard because the rims & tires are usually removed from cars when
they arrive at the junkyard, leaving the cars sitting on the
undercarriage metal parts.



Here's a closeup of the tools that you use to remove the watts rear
linkage nut.

If you're shopping a used police cruiser rear axle assembly, pay close
attention to this area. Sometimes, the stud breaks during aggressive
driving, but it's almost never a problem in civilian use.

Normally, a rear axle assembly would be attached to these control arms.



Here's how the rear axle assembly looks from the side with the springs
removed

And from the other side of the car


This is a 3.55 locker rear axle. You can tell by the s-spring in the
middle that it's a locker

And if you rotate the gear over, you can find stampings to tell you
it's a 3.55 ratio gear set




Here's the identification tag from the rear axle assembly



The hats on these new aftermarket brake rotors are powder coated to
slow corrosion



Here's one of the new axles next to the old ones. OEM ford axles with
antilock brake tone rings only came on cars with a factory installed
antilock brake system. But aftermarket ones for cars without antilock
brakes sometimes have the abs exciter rings on them.



Here's the rear axle assembly ready to slide the axle shafts in

And here's the rear axle assembly with the cover removed and the
carrier rotated so that the lock shaft and lock bolt are accessible.
