Brake Load Sensor Proportioning Valve
NOTE:
All fluids should be at specified levels (fuel tank full) and spare tire, jack, hand tools and floor mats should be in their stowed positions.
Measure spring length with vehicle in unloaded position. Spring length "A" should measure 6.25-6.37" (158.8-161.8 mm). See Fig 1 . If spring length is not as specified, sit on rear of vehicle then slowly get off. This will stabilize suspension deflection. Loosen eye bracket bolts. Adjust spring length by moving bracket. Tighten bracket bolts to 14 ft. lbs. (19 N.m). See Fig 2 .
