Which components hold semi-floating axles in the carrier housing?

• A. Bolts
• B. Snap rings
• C. Seal retainer plates or "C" Locks
• D. Retaining clips

Answer: (C)

In a semi-floating axle setup, the axle end is kept inside the differential carrier by a seal retainer plate that fits around the axle and sits against the seal. The plate is secured with locking pieces, often called C-clips or "C" locks, which grab into a groove on the axle to prevent axial movement. This arrangement both holds the axle in place and keeps the oil seal properly seated, preventing leakage and keeping lubrication inside. Bolts or simple snap rings aren’t the primary retention method for this design, and the locking plate with C-clips is what physically retains the axle in the carrier.
