I tried switching my 2004. 5 2500 stock rims for alloy to free up carry capacity. My son has them on his 2004 3500. When I took them to be mounted I found the rear axle seems to have a slight lip such that the rims won't seat flush on the hub.
Does anyone know why this would be? Neither of us knows why.
