assembly difficult.

Important: Carefully insert the axle shaft in order to not damage the seal.
2. Slide the axle shaft into place allowing the splines to engage the differential side gear.

4. On axles with a locking differential, keep the pinion shaft partially withdrawn.
5. Install the brake drum.
6. On axles with a locking differential, place the C-lock (1) on the axle shaft (3) so that the ends are flush with the thrust block (2).
