After seeing that submerged axle thread I got to thinking about what other maintenance items I need to address, axles included, which I don't do now. Please take a look at my current regimen and let me know what else I need to be doing to keep this truck on the road. 5K - Rotella 15W40, Fleetguard Oil filter, tire rotation10K - Fleetguard Fuel filter25K - BG Transmission Fluid Exchange - O'Reilly's ATF+4100K - BHAF changeI guess I need to do axles too but I don't know how or really anything about it - mileage, type of oil, etc.Thanks fellas!
