2003 Ford Truck Expedition Suspension – Air Suspension Height Sensor Linkage Loose Service Procedure

download
ISSUE Some 2003-2006 Expedition and Navigator vehicles equipped with an air suspension may exhibit an air suspension height sensor linkage arm disengaging from the suspension ball stud or height sensor rotating arm. This concern typically occurs with the rear sensor (Figure 1) but may occur with the front sensors as well. If this occurs, the symptom will typically be the vehicle leaning to one side, the vehicle sitting too low/high, a harsh ride, and/or an inoperative air suspension. In addition, this concern may result in diagnostic trouble code (DTC) C1725 (air suspension front pneumatic failure) or C1726 (air suspension rear pneumatic failure). ACTION When a linkage arm becomes disengaged, do not re-attach the arm and do not replace the sensor unless broken. Instead, install a revised linkage arm on all three (3) sensor assemblies, even if they have not detached from the ball stud. 1. Replace linkage arms on all three (3) sensor assemblies following Workshop Manual (WSM), Section 204-05. 2. Discard the old linkage arms. NOTE IF THE SENSOR ASSEMBLY NEEDS TO BE REPLACED FOR ANY DAMAGE/FAILURE OTHER THAN THE ONE DESCRIBED IN THIS TSB, THE REPLACEMENT ASSEMBLY IS SUPPLIED WITH A NEW STYLE LINKAGE ARM, SO THERE IS NO NEED TO ORDER ADDITIONAL LINKAGES FOR THE SERVICE REPAIR. WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage OPERATION DESCRIPTION TIME 061510A 2003-2006 0.4 Hr.

Steering, Brake And Suspension Specialists Proportioning Valve Diagram

download
This diagram is the most common way to plumb a proportioning valve. In some cases, the right front line will be plugged off at the proportioning valve and the left front line will go to a “T” fitting. From the “T” fitting, the front lines then split off and go to the left and right wheels. Our proportioning valve has a warning light switch built in (this is not a stop light switch.) The warning light will detect any loss of pressure, for example, a leaky wheel cylinder. We recommend you wire this light into your system. Any two wire light socket will work. One wire goes to the accessory power and the other goes to the warning light. Our proportioning valves provide four functions: 1. Proportion pressure front and rear 2. 10 psi. residual check valve 3. Metering valve to apply pressure to the rear brakes before the front brakes 4. A brake warning light to detect a loss in pressure Proportioning Valve Plumbing Diagram: There are two proportioning valve lines that connect to the master cylinder provided in our kits. The first is a 90 degree bend with one leg longer than the other. This line must be oriented with the long leg connected into the front top hole of the proportioning valve and the short end in the front hole on the master cylinder. The second line has two 90 degree bends and has color coded fittings. The larger blue fitting goes into the back hole on the master cylinder and the smaller gold fitting goes into the back top hole on the proportion valve as shown in the diagram
