Abstract
An axle module is obtained by coupling an axle member and a pair of leaf springs in the same vertical relationship as in the actual state of use. At such time, when the axle member is disposed on a work stand, pins passing through holes provided in the right and left leaf springs for mounting to a vehicle body are inserted prior to tightening U-bolts used to mount the leaf springs. In addition, by applying a small force, the axle member can be moved in-plane within a predetermined range relative to the leaf springs. Furthermore, the tightening of nuts is carried out by moving tightening tools disposed on a carriage to a position underneath the tips of the U-bolts subject to tightening and then raising and rotating sockets installed in the tightening tools.
