Snap Ring holding axle in place

.
Explain ALL please.

If rhe clip is missing or fails the axle along with the bearing assemble can slide out.

If you remove the 5 nuts you pull the axle assemble out but the backing plates do not come off because the brake lines are still attached to them.

The axle, and everything attached to it. If the bearing is the same diameter or smaller then the hole in the retainer, it's all comin out if that snap ring fails.
