Hi everyone:

I have an 02 Grand Caravan Sport with ABS and I have a problem with my right rear brake assembly.

The bolt hole for the caliper pin on my (what I believe is called) Caliper adapter (houses the emergency brake shoes, etc) is stripped and I tried using a helicoil but got sold the wrong size, and now it's ruined and the whole unit has to be replaced

Anyway, I've removed the whole thing, hub and bearing assembly and the adapter. Trouble is I can't find a replacement part at the parts store....All they have are the hub assembly but, no Caliper adapter part.

How do I find this part? Do I have to go to a yard and pull it off another? Am I even calling it the right thing? Finally, does it pull away from the hub assembly or is it one unit?

Any help would be appreciated!

 

Here are the Mopar part numbers, right side 5073640AA and left side 5073641AA. and here is a tech bullentin too.

8. Remove the driveshaft from the rear driveline module and hub/bearing. The driveshaft
is removed by first compressing the inner joint on the driveshaft and removing it from the
driveline module. Then, slide the outer joint of the driveshaft out of the hub and bearing.
9. Release the parking brake.
10. Create slack in the rear parking brake cables by locking out the automatic adjuster
as described. Grasp the exposed section of the front park brake cable and pull
downward on it. Then install a pair of locking pliers on the front brake cable just
rearward of the second body outrigger bracket.

11. Remove the park brake cable from the adapter by:
a. NS/GS vehicles: removing and discarding the horseshoe clip from the
retainer on the end of the park brake cable.
b. RS/RG vehicles: removing the park brake mounting bolt.
12. Remove the end of the park brake cable from the actuator lever on the adapter.
13. Remove the park brake cable from adapter by using a 1/2” wrench slipped
over the park brake cable retainer as show in to compress the
locking tabs on the park brake cable retainer.

14. Remove the disc brake caliper to adapter guide pin bolts.
15. Remove caliper from the adapter using the following procedure:
a. Rotate rear of caliper up.
b. Pull the front of the caliper and the outboard brake shoe anti-rattle clip out
from under the front abutment on the adapter.
16. Support the caliper to prevent the weight of the caliper from damaging
the flexible brake hose.
17. Remove the rotor from the hub/bearing.
18. Remove the four hub/bearing to axle mounting bolts.
CAUTION: CORROSION MAY OCCUR BETWEEN THE HUB/BEARING AND THE
AXLE. IF THIS OCCURS THE HUB/BEARING WILL BE DIFFICULT TO REMOVE
FROM THE AXLE. IF THE HUB/BEARING WILL NOT COME OUT OF THE AXLE
BY PULLING ON IT BY HAND, DO NOT POUND ON THE HUB/BEARING TO
REMOVE IT FROM THE AXLE. POUNDING ON THE HUB/BEARING WILL DAMAGE
THE HUB/BEARING. TO REMOVE A HUB/BEARING WHICH IS CORRODED TO
THE AXLE, LIGHTLY TAP ON THE DISC BRAKE CALIPER ADAPTER USING A
SOFT FACE HAMMER. THIS WILL REMOVE BOTH THE DISC BRAKE CALIPER
ADAPTER AND THE HUB/BEARING FROM THE AXLE. THE HUB/BEARING WILL
THEN NEED TO BE REMOVED FROM THE CALIPER ADAPTER.
19. Remove the hub/bearing from the axle.
20. If the disc brake caliper adapter and hub/bearing were removed as an assembly and
the two cannot be separated by hand, use the following procedure:
a. With a helper supporting the caliper adapter in his hands, position Remover,
Special Tool 8214–1 on the cast housing of the hub/bearing.
NOTE: DO NOT POSITION SPECIAL TOOL ON THE INNER RACE
OF THE HUB/BEARING.
b. Lightly strike Remover Special Tool 8214–1 with a hammer to remove
the hub/bearing from the caliper adapter. HUB/BEARING REMOVAL FROM CALIPER ADAPTER

21. Using the parking brake anchor boss on the adapter as a clamping point, place the
adapter in a vice. Inspect the parking brake hardware (shoe, return springs, adjuster) for
damage and wear. Any part that is damaged or worn must be replaced by new parts.
22. Remove the park brake hardware (including the rubber access plug) from the
adapter and install park brake hardware on the new adapter.
23. Install the new adapter on the axle.
24. Install the hub/bearing on the end of the axle.
25. Install the hub/bearing mounting bolts. In a progressive crisscross pattern, tighten
the 4 mounting bolts until the caliper adapter and hub/bearing are squarely seated
against the axle. Tighten mounting bolts to a torque of 129 N·m (95 ft. lbs.).
26. Install the wheel speed sensor on the hub/bearing and adapter and
torque attaching bolt to 12 N·m (105 in. lbs.).
27. Using the alignment mark from step 5, install driveshaft in hub/bearing and on
output shaft of rear drive line module. Driveshaft is installed by first sliding
the outer joint of the driveshaft into the hub/bearing and then compressing the
inner joint on the driveshaft and installing it on the output shaft of the driveline
module. Do not tighten mounting bolts at this time.
28. Install the park brake cable into its mounting hole in the adapter.
NOTE: BE SURE ALL THE LOCKING TABS ON THE PARK BRAKE
CABLE RETAINER ARE EXPANDED OUT TO ENSURE THE CABLE WILL
NOT PULL OUT OF THE ADAPTER.
29. Install the end of the park brake cable on the park brake actuator lever.
30. For NS/GS vehicles, install a NEW horseshoe clip on the park brake cable retainer.
The horseshoe clip must be installed with the curved end of the clip pointing straight
up and the edge of the curved end facing the rear of the vehicle. For RS/RG
vehicles, install the park brake cable mounting bolt to the adapter.
31. Using Gauge, Brake Shoe, Special Tool C-3919 or an equivalent, adjust the
rear park brake shoe to park brake drum clearance.
32. Install rotor on hub/bearing.
33. Carefully lower the disc brake caliper and brake shoes over the rotor and onto the
caliper adapter by reversing the removal procedure in step 15.
CAUTION: WHEN INSTALLING THE GUIDE PIN BOLTS, EXTREME CAUTION SHOULD
BE TAKEN NOT TO CROSS-THREAD THE CALIPER GUIDE PIN BOLTS.
34. Apply brake grease p/n J8993704 to caliper guide pin bolts and install caliper
guide pin bolts. Torque to 22 N·m (192 in. lbs.).
35. Clean all foreign material off the threads of the outer C/V joint stub shaft. Install
the washer and hub nut on the stub shaft of the outer C/V joint.
36. Remove the locking pliers from the park brake cable and lower the vehicle.
37. Set the parking brake. This is required to keep the driveshaft from
rotating when tightening and torquing the hub nut and driveshaft inner
joint to driveline module mounting bolts.
38. Raise the vehicle.
39. Tighten the driveshaft inner joint to driveline module output shaft mounting
bolts (Fig. 2) to a torque of 61 N·m (45 ft. lbs.).
40. Tighten the outer C/V joint hub nut to a torque of 244 N·m (180 ft. lbs.).
41. Install the spring washer, nut retainer and a new cotter pin on the
stub shaft of the outer C/V joint.
42. Install tire and wheel assembly.
43. Tighten wheel mounting stud nuts in a crisscross sequence until all nuts are torqued to
half specification. Then repeat the tighten sequence to full torque of 135 N·m (100 ft. lbs.).
44. Replace the left rear adapter using steps 2 through 43.
45. Lower the vehicle.
46. Fully apply and release the park brake pedal one time. This will seat and
correctly adjust the park brake cables.
CAUTION: BEFORE MOVING THE VEHICLE, PUMP THE BRAKE PEDAL
SEVERAL TIMES TO INSURE THE VEHICLE HAS A FIRM BRAKE PEDAL
TO ADEQUATELY STOP THE VEHICLE.
