Dodge Durango (HB). Manual — part 55
14. Slowly tighten pinion nut in 6.8 N·m (5 ft. lbs.)
increments until the desired rotating torque is
achieved. Measure the rotating torque frequently
with an inch pound torque wrench (2) to avoid
over crushing the collapsible spacer.
15. Check pinion rotating torque with an inch pound
torque wrench. The pinion rotating torque should
be:
•
Original Bearings: 1 to 3 N·m (10 to 20 in. lbs.).
•
New Bearings: 2 to 5 N·m (15 to 35 in. lbs.).
16. Position exciter ring on differential case. With a
brass drift, slowly and evenly tap the exciter ring
into position.
17. Position ring gear on the differential case and
start two ring gear bolts. This will provide case-to-
ring gear bolt hole alignment.
18. Invert the differential case in the vise.
19. Install new ring gear bolts (2) and alternately
tighten to 156 N·m (115 ft. lbs.).
CAUTION: Never reuse the ring gear bolts. Failure
to follow these instructions will result in bolts
fracture.
20. Install differential in housing and verify gear mesh
and contact pattern.

DIAGNOSIS AND TESTING
BASE BRAKE SYSTEM
Base brake components consist of the brake pads, calipers, brake drum in hat rotor in the rear, rotors, brake lines,
master cylinder, booster, and parking brake components.
Brake diagnosis involves determining if the problem is related to a mechanical, hydraulic, or vacuum operated com-
ponent.
The first diagnosis step is the preliminary check.
PRELIMINARY BRAKE CHECK
1. Check condition of tires and wheels. Damaged wheels and worn, damaged, or underinflated tires can cause pull,
shudder, vibration, and a condition similar to grab.
2. If complaint was based on noise when braking, check suspension components. Jounce front and rear of vehicle
and listen for noise that might be caused by loose, worn or damaged suspension or steering components.
3. Inspect brake fluid level and condition. Note that the brake reservoir fluid level will decrease in proportion to
normal lining wear. Also note that brake fluid tends to darken over time. This is normal and should not be
mistaken for contamination.
a. If fluid level is abnormally low, look for evidence of leaks at calipers, wheel cylinders, brake lines, and master
cylinder.
b. If fluid appears contaminated, drain out a sample to examine. System will have to be flushed if fluid is sep-
arated into layers, or contains a substance other than brake fluid. The system seals and cups will also have
to be replaced after flushing. Use clean brake fluid to flush the system.
