Can’t Dodge® this Durango®
Pulsation
Eric Seifert, Automotive Technical
Editor
Paul likes jammin’ to all the latest tunes
in his 2004 Dodge Durango. His mobile DJ business makes good use
of the Durango’s room to transport equipment from gig to gig.
On his way home from a wedding reception Sunday, Paul noticed a
different kind of pulsation in the Durango. It only would occur
when he lightly applied the brakes over 60 mph. I booked Paul for
a gig in my shop on Tuesday.
The vehicle may exhibit pulsation or vibration
in the brake pedal and/or steering wheel when the brakes are applied.
The condition is most noticeable at speed over 50 MPH but can occur
at lower speeds. If the customer indicates that the condition is
present, perform the Repair Procedure. The procedure involves installing
brake pads, resurfacing the rotors and checking rotor runout.
1 Set of Brake
Pads, P/N 05139733AA, will be required to complete the repair.
Applicable Vehicles: 2004-2005 Durango (HB)
Repair Procedure:
(Review safety procedures in the ALLDATAdiy.com®
before beginning)
1. Inspect
the front brakes for any signs of abnormal wear or damage. Repair
as necessary.
2.
Resurface the front brake rotors with a Chrysler® approved on-car
brake lathe. If an on-car lathe is not available, the rotor resurfacing
must be sublet to a facility with an approved on-car lathe.
3.
Remove the calipers.
4.
Clean the caliper adapter.
5.
Replace the front pads and anti-rattle springs with P/N 05139133AA.
6.
Mark one wheel stud on each side with a dab of paint or suitable
marker.
NOTE: Wheel stud torque is critical to the success
of the repair. The following procedure is intended to identify excessive
rotor distortion which could be caused by improper wheel stud torque.
 7.
Install the wheel and assembly to the hub.
Pre-tighten the lug nuts in a cross pattern to 100 Nm (75 ft.lbs.)
then final tighten the lug nuts in a cross pattern to:
200 Nm (145 ft.lbs.) for steel wheels or 175 Nm (130 ft.lbs.) for
aluminum wheels. Mark the wheel at the same location as the marked
wheel stud.
8. Set
up a dial indicator to measure mounted rotor runout. Place the dial
indicator plunger against the inner machined rotor face, visible
between the brake caliper and the front splash shield (Fig.
1). Rotate the wheel and tire assembly two turns and take
runout measurement. If the measurement is less than .025 mm (.001
in.) no further action is required. If the measurement is greater
than .025 mm (.001 in.) remove the lug nuts and relocate the wheel
one stud clockwise, tighten the lug nuts as described in step 7
and check the runout again. Do not remove any brake parts. Repeat
step 8 for each wheel location until you achieve the lowest mounted
runout. Minimum mounted rotor runout will be achieved by moving
the wheel, not the rotor.
