23105S Carrier to Housing Leak Repair Procedure
Spicer ®
Drive Axles
P/N: SHAIS141B
This document describes the recommended repair procedure for a leaking carrier-to-housing joint on a 23105S drive axle.
The new boss support bracket and capscrews are specifically designed to repair carrier-to-housing leaks occurring at the
6:00 position. The new parts when installed properly are designed to give added support at the joint area of the carrier
flange where high concentration’s of loading occurs from vehicle articulation and housing flexing.
Dana Axle Housing Hardware Kit P/N: 512097
Installation Instructions:
1. Block vehicle tires.
2. Disconnect driveline.
3. Drain axle lube into a clean pan. Lube will be reused at the end of this procedure.
4. Remove axle shaft nuts, washers and shaft.
5. Remove all but one carrier fastener. The remaining capscrew will hold the carrier in place until the transmission jack
and adapter plate are moved in place and secured.
6. Install alignment studs at the 3:00 and 9:00 positions of the carrier.
Carrier Removal
WARNING: IT IS IMPORTANT THAT YOU OBSERVE ALL OF THE NORMAL SAFETY PROCEDURES, INCLUDING
WEARING PROPER PROTECTION FOR EVERY STEP IN THIS PROCEDURE.
1. Mount the adapter plate to a transmission jack. Remove pinion cage cap screws at 5:30 and 7:30 positions.

2. Position the adapter plate and adjust transmission jack table to alien bolt holes.
3. To fasten the adapter plate to the pinion cage install 2 HCS ¾” x 3” capscrews and snug with impact gun.
Position Adapter Plate Install ¾” x 3” Capscrews
4. Remove remaining carrier to housing capscrew and carefully remove the carrier assembly.
Carrier Flange and Housing Ring Cleaning
Note: Before installing new fastener hardware or the carrier assembly, inspect the axle housing visually for
cracks, nicks or burrs on all machined surfaces. It is important that all surfaces are cleaned properly.
1. Use a wire wheel to remove any paint, old sealant or oil from the housing and carrier mounting surfaces. Wipe
surfaces down with cleaning solvent to remove any residual oil or dirt.
Wire Wheel Surfaces Check for Nick, Cracks and Contamination
2. Apply a 1/8” bead of Loctite 5699 Ultra Grey or Dow Corning 3-0100 Automotive Sealant to the housing surface, it’s
important to apply the sealant around (make a loop) all of the threaded bolt holes.
IMPORTANT: Do not spread or smooth-out RTV once applied. RTV will set in 20
minutes. Install carrier before RTV sets or reapply.
1/8” Bead of Approved RTV Make loop around all bolt holes

Carrier Reinstallation
1. Adjust the Transmission jack to start the carrier on the guide pins.
Note: The carrier may have moved forward when it was removed from the housing, the transmission jack
table should be readjusted to compensate for this movement.
2. It is important that the carrier is at the same angle as the housing. The gap between the carrier flange and the housing
ring should be the same all the way around.
Adjust Jack to Start Carrier on Guide Pins Same Gap Top-to-Bottom and Right-to-Left
3. Raise or lower the assembly until it slides into place. If it does not slide in easy, check the carrier-to-housing
alignment. Right-to-left, top-to-bottom.
4. Disconnect carrier adapter plate. Apply Loctite 277 to the threads of the original pinion cage capscrews, reinstall and
torque to 240 – 300 ft. lbs.
Apply Loctite 277 Reinstall Capscrews
5. Install at least one of the new carrier fasteners to hold the carrier in place so you can remove the alignment studs.
6. Remove the alignment studs.
7. Install new carrier to housing fasteners to all but the bottom two positions. The 5:30 and 6:30 positions will utilize two
unique 3” long capscrew to mount the boss support bracket.

8. Position the boss support bracket so that the side with the machined raised area is facing the carrier flange surface.
Boss Support Bracket Raised Area Faces the Carrier Flange
9. Install two 3” long capscrew, and torque to 250 –270 ft. lbs.
10. Torque remaining carrier to housing fasteners in a crisscross pattern to 250 – 270 ft. lbs.
11. Clean axle shaft flanges and wheel hub surfaces and install new axle shaft gasket.
12. Reinstall the axle shaft, washers and nuts, torque to spec.
13. Reinstall the driveline.
Raised Area
14. Remove fill plug from housing cover and refill the housing using the same lubricant that was removed. If needed, add
lube and fill until level with the bottom of the fill hole.
