To remove and install halfshafts on 325iX models, several special tools are needed. These include 33 4 050 and DD 5 500 for driving in a new lock plate for the brake disc, 342 2 070 for pressing off the tie rod, and 31 2 160 for pressing off the control arms. To press the output shafts out of the brake discs, use 33 2 112 and 33 2 113, and to press them back in, use 33 2 112, 33 2 124, and 33 4 042. On the left side, the output shaft is pulled out of the axle shaft with 315 011 and 30 31581, while on the right side, 31 5 011 and 31 5 012 are used.

On the right side, install 31 5 012 and 315 011, and again screw the 2 bolts in alternately to remove the shaft from the differential. When installing the halfshafts, make sure the snapring inside engages in the groove of the shaft. Coat the spline with light oil before installing the shafts into the steering knuckle.
