All Models
- With vehicle on level surface, fuel tank full and no other load, jounce both front and rear until suspension settles. On E100/350 models, place 2 height blocks 3 1/2" high between top of axle and flange on lower part of jounce bracket on each axle.
- Measure clearance at inside area of jounce bracket (toward wheel) between top of axle and spring seat lower surface on frame.
- On Bronco, Bronco II, Ranger, and F100/350 models, place 2 height blocks 5" high between top of axle and outside lip of jounce bumper on each axle.
- Measure clearance at inside of spring seat lower surface (toward center of vehicle) between top of axle and spring seat lower surface. If clearance is not correct, height must be corrected by installing proper springs or shims.
