Topic: Drive Axle Carrier Assembly Prep and Replacement
Please watch video for complete instructions.
Prep:
- Install guide pins at 3 and 9 o’clock
- Clean the carrier ring surface with an abrasive pad
- Inspect for cracks, nicks, and burrs, or anything that might affect sealing
- Replace damaged fasteners
- Check for loose studs or cross-threaded holes
- Use a good solvent to remove gunk, debris, or old RTV
- Use Dana-approved RTV and practice good RTV use (cut tube to 1/8 inch, don’t flatten beads, don’t overuse)
- Apply at the center of the carrier ring, then around the bolt holes
Install assembly:
- Put carrier on guide pins
- Align the splines of the output shaft to the output side gear
- When carrier is on the pins, lower the hoist enough to disconnect the chains
- Put on the stud washers, nuts, and bolts
- Snug bolts in a crisscross pattern
- Take out guide pins
- Torque down to spec
Put in axle shaft gasket:
- Do not mix up the shafts
- Put shaft back in
- Reinstall the washers and nuts. Torque to OEM specs
Install driveshaft:
- Make sure bearing cups are completely seated between yoke nibs
- Torque the strap bolts to spec
- Refill the axle with new lube so the lube level is at the bottom of the fill hole
- Lube should be ready to run out
