RE: Lug Torque
Hmm..so if I understand correctly its now 135? Also where can I find documentation not to put a plug into radial tires. I want to print it out and show the guys at Wal-Mart.
Edit: So I'm looking through some stuff on the net and I come across this http://www.kaltire.com/commercial/me...res/repair.php Now thats saying to use a plug and a patch. I was watching from a distance the guy doing the repairs and I do remember him using a sander on the inside of the tire. Should it be safe to assume that was from him prepping the area for the patch?

RE: Lug Torque
Patching is the best way on a radial. if you have watched them install a plug, it often requires that the hole be made larger. When you do this on a radial it can/will get into the belts and further weaken the tire by cutting them. I'm sure that somebody has a different feeling on this though.
Concerning the TSb mazz posted. Did I miss something in there. It seems that what is being described is a troubleshooting procedure for the rotors. I didn't see anything saying the final torque should be reduced to 100 ftlbs. Thanks.

NUMBER: 05-003-04
GROUP: Brakes
DATE: June 8, 2004
THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 05-008-03, DATED
NOVEMBER 28, 2003, WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL
REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND A REVISION TO THE
WHEEL, LUG NUT TORQUE AND CLARIFICATION THAT THE REPAIR APPLIES TO
1500 SERIES TRUCK ONLY.
SUBJECT:
Brake Shudder or Vibration
OVERVIEW:
This bulletin involves installing brake pads, calipers, resurfacing the rotors and checking
rotor runout.
MODELS:
**2003 (DR) Ram Truck (1500 Series Only)**
SYMPTOM/CONDITION:
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.
DIAGNOSIS:
If the customers indicate that the condition is present, perform the Repair Procedure.
PARTS REQUIRED:
Qty. Part No. Description
1 05080556AF Brake Pads - Vehicles built prior to March 6, 2003
(MDH 0603XX)
1 05139733AA Brake Pads - Vehicles built after March 6, 2003 (MDH
0603XX)
1 05134582AB Caliper , Right (2003 Only)
1 05134583AB Caliper, Left (2003 Only)
NOTE: 2004 vehicles are already equipped with the calipers listed above. Do not
replace calipers on 2004 vehicles.
REPAIR PROCEDURE:
1. Inspect the front brakes for any signs of abnormal wear or damage. Repair as
necessary.
2. Resurface the front brake rotors with a DaimlerChrylsler approved on-car brake lathe.
If an on-car lathe is not available at the dealership, the rotor resurfacing must be sublet
to a facility with an approved on car lathe.
3. Remove the calipers.
4. Clean the caliper adapter and lubricate the adapter and anti-rattle springs with
MOPAR brake grease.
5. Install new calipers, p/n's 05134582AB and 05134583AB.
6. Replace the front pads and anti-rattle springs with the appropriate part number listed in
the Parts Required Section above.
7. Bleed the system.
8. 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.
9. Install the wheel and pre-tighten the lug nuts in a cross pattern to: 70 Nm (50 ft. lbs.)
then final the lug nuts in a cross pattern to: **183 Nm (135 ft. lbs.)** and mark the
wheel at the same location as the marked wheel stud.
10. 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 .050 mm (.002 in.) no further
action is required. If the measurement is greater than .050 mm (.002 in.) remove the
lug nuts and relocate the wheel one stud clockwise, tighten the lug nuts as described
in step 6 and check the runout again. Do not remove any brake parts. Repeat step 7
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.
