AXLE HOUSING HARDWARE KIT – THICK FLANGE CARRIERS – DANA P/N: 512087

Installation Instructions:

1. Block vehicle tires and disconnect driveline

2. Drain lube and remove axle shafts

3. Remove old carrier fasteners and carrier assembly

4. Before installing new fastener hardware or the carrier assembly, the axle housing should be visually inspected for cracks, nicks or burrs on all machined surfaces. Clean the threaded bolt and stud holes in the axle housing, removing any paint, old sealant or oil from the housing and carrier mounting surfaces.

5. Apply a bead of approved RTV sealant to the housing surface; it’s important to apply the sealant around (make a loop) all of the threaded boltholes. Reinstall the carrier assembly.

6. Install new fasteners supplied in kit.

7. Torque the capscrew or nut to the correct specification listed in the chart below. If installing studs be sure to install them to the proper specification outlined below.

Important! Dana does not recommend mixing old and new carrier fasteners on the same carrier. If reusing

old fasteners, use Loctite correct specification. Final torque values of hardware fasteners must be measured using a calibrated torque wrench.

Installation Instructions: Carrier-to-Housing Studs

Install carrier-to-housing studs into housing until 2 full thread is visible, being careful not to drive or install it too far. The stud should extend out from the face of the housing approximately 1-11/16” (43mm).
