Spicer Differential Cover Bolt P/N:34279

Clamp the differential cover tight and keep gear oil sealed inside the axle housing with the Dana Spicer Differential Cover Bolt 34279. This genuine Spicer fastener threads into the axle housing to hold the differential cover in place and maintain clamping load on the cover gasket or sealant. It's cataloged for both FRONT and REAR differential positions, and drops in as a direct-fit replacement across a huge range of listed applications — including the 1970-1974 Volvo 142, 1969-2002 Pontiac Firebird, 1995-2013 Chevrolet Tahoe, 2005-2008 Nissan Armada, and 2005-2015 Nissan Xterra. See the Buyer's Guide tab for the full list of 359 applications.

• Genuine Spicer: Dana design, engineering, testing, and manufacturing work together for performance non-genuine parts can't match.
• OE quality: built to meet the OE standards set by Dana, then tested and proven.
• Validated to spec: tested against rigorous OE specifications, with the latest production upgrades so it's as good as or better than the part it replaces.

Worn, corroded, or stripped cover bolts can weep gear oil past the cover seal. If a damaged bolt is behind your leak, this genuine Spicer replacement helps restore proper clamping load.
