Topic: Bolt-On Housing Cover Service Parts Hardware Change
Affected Models: All D190, R190, S190 and D590 Rear Housing Covers
Dana engineering has identified a stack-up issue on D190, R190, S190 and D590 rear housing covers. The covers flange
thickness may be thin enough so that the shank of the 55mm capscrews could bottom out on the housing ring surface.
This condition could cause a loss of clamp load on the fastener which could result in a lubrication leak. Vehicles that have
been identified as having a rear cover leak should be repaired with the existing hardware kit listed below. This kit has
been updated to include washers that will be installed behind each capscrews to eliminate any interference.

Fastener Installation Instructions:
1. Before installing new fastener hardware or the cover assembly, the axle housing should be visually inspected for
cracks, nicks or burrs on all machined surfaces. Clean the threaded bolt holes in the axle housing, removing any
paint, old sealant or oil from the housing and cover mounting surfaces. Studs need to be replaced only if the stud
came out with the nut at the time of disassembly.
2. Apply a 1/8” bead of approved RTV sealant to the housing surface; it’s important to apply the sealant around (make a
loop) all of the threaded bolt holes. Reinstall the rear cover assembly.
3. Install new washers, capscrews and nut supplied in kit.
4. 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.
Installation Instructions: Cover-to-Housing Studs
Install carrier-to-housing studs into housing until the exposed height is 38mm (1.5”) above the housing ring.
Important! Dana does not recommend mixing old and new carrier fasteners on the same carrier. If reusing old fasteners, use
Loctite® 277 or 271 (which is red in color) on the threads of the old fastener and torque to correct specification. Final torque
values of hardware fasteners must be measured using a calibrated torque wrench.
