NOTE:

With lock carrier installed, engine is removed downward together with the transmission and the subframe.

During installation, all cable ties must be installed at the same location.

All bolts on suspension components must be equipped with bonded rubber bushings and tightening in curb weight position (no load).

Bonded rubber bushings have a limited range of motion. Axle components with bonded rubber bushings must be brought into the position they will be in during driving before tightening (curb weight position). Otherwise, the bonded rubber bushing will have tension, which will reduce the service life.

Before starting work, determine the measurement -a-, for example with tape measure, from center of wheel to lower edge of wheelhouse.

The measurement must be performed in curb weight position (unloaded condition).

Note the measured value. This number will be needed when tightening the bolts/nuts.
