 Before changing the unit, perform the following checks:

With the engine off and all vacuum depleted from the booster, check the pedal action. It must be high and hard. If it is not, either the master cylinder is bypassing or something else in the system is causing the low pedal (check ABS valve if so equipped, all flexible brake hoses, or for air in ford truck 2system). Note that the booster cannot cause a dropping pedal — it either works or the pedal will be hard.

For 10-4007 (without cruise), upgrade to 10-2827. For 10-2690 (with cruise), upgrade to 10-2828.

Axle Torque Procedures

Guessing the correct torque setting is a bad idea.

The physics of all threaded fasteners are the same. As the bolt and nut are turned, the spiral threads convert rotational force into a linear force that creates clamping loads. When a threaded fastener is tightened, it stretches. Since metal is elastic, even greater clamping loads are generated. The threads also generate friction that keeps the assembly together. This especially applies to wheel bearings and axle nuts.
