Brake Load Sensor Proportioning Valve Adjustment
NOTE:
All fluids should be at specified levels 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 5.94-6.06" (151-154 mm). If spring is not as specified, sit on rear of vehicle then slowly get off. This will stabilize suspension deflection. See Fig 1 . Loosen eye bracket bolts. Adjust spring length by moving bracket. Tighten bracket bolts to 13-15 ft. lbs. (17-21 N.m). See Fig 2 .
