Diff cover rusted through


Recommended Posts

Newby here.

 

2005 2500HD w/6.0L gas 48,000 mi.

 

Just the other day I noticed a small amount of gear oil on the garage floor. Inspection shows a heavily rusted diff cover and oil has started to weep through the cover itself. No, it isn't the gasket or the driveshaft seal.

Worse is the fill hole is rusted TIGHT.

 

Will an aftermarket 14 bolt cover for a diesel fit my diff? All HD differentials are the same for 2500's aren't they? Need to find one with a fill hole.

 

Thanks. John

Diesel and gas use different differentials. Gas is the 10.5" and diesel is the 11.5".
