04 2WD rear diff whine: Need DRK303...and?
I have the whine at 60-65 mph. Based on the threads I've read, it looks like it's the pinion bearing. I'm considering picking up a Timken DRK303 rebuild kit:
I have access to a lift, tools, etc. So, is there anything else I need? Other gaskets that I'll break that aren't included in this kit, for instance? I've been looking around for a walk-through on this but I haven't had any luck. I've gone through the RepairPath documentation but it looks like I'll need a little more experience before I'll be able to put their documentation to use.
Oh: And do people call this different things? The more I Google the more I see people mixing phrases in threads. "Rebuild the rear end, rear axel, rear diff, etc"

SUBJECT:
Rear Axle Whine-Like Sound - Only At Vehicle Speeds Greater Than 55 MPH
OVERVIEW:
This bulletin involves the installation of a body/frame damper at the C-Pillar.
MODELS:
2004 - 2007 (HB/HG) Durango / Aspen
SYMPTOM/CONDITION:
While driving, the customer may experience an axle whine-like sound coming from the rear
of the vehicle (rear axle). The specific axle whine-like sound will occur when the rear axle
is fully warm and only at vehicle speeds that are greater than 88 Km/h (55 MPH). The rear
axle whine-like sound will occur more frequently during light acceleration (drive side), or
while maintaining vehicle speed (off throttle / coast) driving maneuvers.
This condition may be due to the axle sound being transmitted into the vehicle body
through the C-Pillar body/frame mount.
DIAGNOSIS:
If the above condition is present perform the Repair Procedure.
NOTE: The Repair Procedure will REDUCE the axle whine-like sound intensity, and
only if the condition occurs when the axle is fully warm and at speeds
GREATER THAN 88 km/h (55 MPH).
PARTS REQUIRED:
Qty. Part No. Description
2 52122188AA Damper, C-Pillar Mass
4 04895415AB Spacer (washer - two per side)
2 06508823AA Screw / Bolt
NUMBER: 03-001-08
GROUP: Axle
DATE: March 14, 2008
REPAIR PROCEDURE:
1. Raise the vehicle on a suitable lift.
2. In front of the left rear wheel, locate the left side C-Pillar body mount consisting of: the
upper body-to-frame isolator and the lower rebound isolator.
3. Leaving the original upper and lower C-Pillar body mount isolators in place (these
isolators will not be replaced), remove and discard the C-Pillar body mount isolator
fastener (bolt).
4. With the original lower rebound isolator held in its correct position on the vehicle,
install the new damper parts in the following order:
a. Place the two spacers (washers) against the lower side of the lower rebound
isolator.
b. Place the mass damper (oriented correctly) against the spacers. The recessed side
of the donut shaped damper will face towards the ground and towards the head of
new fastener (bolt head).
c. Place the new longer fastener (bolt) through the mass damper, both spacers, lower
rebound isolator, vehicle frame, upper body-to-frame isolator, and into the body.
5. Verify at all components are installed correctly. If installed correctly the new mount
component order should be from top to bottom: the vehicle body, body-to-frame
isolator, vehicle frame, lower rebound isolator, two new spacers, the new mass
damper (oriented correctly with recessed side towards the ground), and the new
fastener (bolt).
6. Tighten the new left side C-Pillar body mount fastener to 81 Nm (60 ft. lbs.).
7. Perform the above procedure to the right side C-Pillar body mount.
8. Lower vehicle.
