Differential Carrier: Removal
WARNING: This page is about a different car, the 2004 Ford F550 Super Duty and 2004 Ford F450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Do not use heat when disassembling a drive axle. To do so will destroy heat treat properties and weaken or distort axle components. Failure to follow these instructions may result in personal injury.
- Steam clean the axle assembly.
- Set the parking brake.
- Chock the wheels.
- Drain the axle lubricant into a suitable container.
- Remove the two bottom carrier bolts to drain the lubricant.
- Disconnect the rear anti-lock brake sensor electrical connector.
- Index-mark and disconnect the driveshaft, and position it aside. Refer to DRIVESHAFT .
- Loosen the pinion hex nut if drive pinion disassembly is necessary.
- Remove the axle shafts. Refer to WHEEL HUBS & BEARINGS - FULL FLOATING AXLE - DANA .
- Remove all but the two top carrier-to-axle housing retaining bolts, noting the length and position of each bolt.
- Remove the carrier from the axle housing.
- Position a suitable jack under the carrier.
- Remove the remaining retaining bolts.
- Use the slots to separate the carrier approximately 25.4-50.8 mm (1-2 inches) from the axle housing.
- Secure the carrier to a suitable jack, and remove the carrier from the axle housing.
- Clean and dry the components as necessary.
- Inspect the gear set for pitting, scoring, wear and damage.
- Inspect the splines for wear, cracking and distortion from twisting.
- Inspect the axle flange O-ring.
- Clean the axle housing interior, the axle and carrier housing sealing surfaces, and the carrier mounting bolt hole threads. Inspect the housing for stripped and damaged threads and bending fatigue.
- If carrier disassembly is necessary, refer to DIFFERENTIAL CASE AND RING GEAR .
CAUTION:
Steam clean the axle prior to removal from the vehicle. Dirt is abrasive and will cause premature wear of otherwise usable parts.
WARNING:
Do not strike the axle shaft flange directly with a steel hammer or sledge. This will crack and splinter the flange. Failure to follow these instructions may result in personal injury.
CAUTION:
Do not pry or chisel the axle shaft flange away from the hub. This will damage the sealing surface.
NOTE:
Mark the left or right axle shaft flange for proper orientation during installation.
WARNING:
Secure the carrier to the jack to prevent it from falling when removing it from the axle housing. Failure to follow these instructions may result in personal injury.
CAUTION:
Alkaline cleaning solutions will damage machine surfaces. Use only emulsion cleaners or petroleum based cleaning solvent.
CAUTION:
Use only soft, clean, lintless towels to dry the components.
CAUTION:
After drying, lightly coat the parts with rust inhibitor or clean lubricant to prevent damage from corrosion. Wrap all parts that are going to be in storage for a prolonged period in wax paper.
NOTE:
The gear set shown removed for clarity.
