Gmc grease fittings
Have a 2011 GMC 3500 Duramax. Two of the grease fittings are hard to get to, would like to change to 90 degree fittings. Does anyone know the tread size of the fittings.

Good info, but his 2011 should only have 9 fittings.

Using benk's pictures which two are missing on the 2011?
