Maintenance Schedule

[el_barto]

Looking at the maintenance schedule in the Owners Manual it calls for Cabin Air Filters every 20k and Engine Air Filters every 30k. 20k for Cabin Air Filters seems ok, maybe a bit on the long side; but 30k for the Engine Air Filter seems super long.
How often do you guys replace the air filters in these trucks? I am thinking Ill do 20k for both Filters…Maybe Ill put in an AFE Dry filter that can just be cleaned.

2019 Power Wagon Hemi 6.4 with ZF 8HP75 Trans. Currently has 12,000 miles.

Heres what my maintenance schedule for the foreseeable future is looking like...
Oil Change + Filter Every 5k.
20,000 - Axle Fluid, Cabin Filter, Engine Air Filter
40,000 - Cabin Filter, Engine Air Filter, Axle Fluid
60,000 - Transmission Fluid and Pan/Filter (8 Years Max), Transfer Case Fluid, Axle Fluid, Cabin Filter, Engine Air Filter
80,000 - Cabin Filter, Engine Air Filter, Axle Fluid
100,000 - Spark Plugs, PCV Valve, Cabin Filter, Engine Air Filter, Axle Fluid
120,000 - Transmission Fluid and Pan/Filter (8 Years Max), Transfer Case Fluid, Axle Fluid, Cabin Filter, Engine Air Filter
140,000 - Cabin Filter, Engine Air Filter, Axle Fluid
150,000 - Coolant Flush (10 Years Max)

Why do you want to change the diff fluid every 20k miles? That’s ridiculous

 

[el_barto]

20k is the suggested interval for “severe service”(police, taxi, fleet, offroad, or frequent towing)...I agree it seems a bit excessive. Maybe 20k for the first (since most of the wear-in happens in this period), then maybe 40k intervals after that?

I usually change my engine air filter every year. For me that is about 20,000 miles. If the cabin air filter is dirty that is one thing, but if the engine air filter is dirty that can make the engine work harder. Also, just take a look and if it is still pretty clean put it back. 40k seems really long to me, even if you do not live in a dusty climate. Also, thanks for the intervals, for me the owners manual was not specific on oil changes at all. To keep from getting the hemi tick I was going to do oil changes(+filter) every 5k as well. I typically changes all the drive terrain fluids every 30-40k. ( both diff, transfer case, drain the transmission pan and replace some fluid + filter, etc). The reason I do the transmission like that is I do not do a full swap so changing some fluid more often keeps it fresher. What I was taught is it never hurts to changes the fluids, it hurts to leave it until it is really dirty then change it, that is when it causes problems. I plan on keeping the truck a long time so changing fluids on my own is not a big deal to me. But thanks for the chart, I might follow some of those change intervals after my first change.

I tow medium to low weight about half the time, and heavy weight about 2-4 times a year. I think you are right about most wear being the first 20k. So I think for me I will change the diff fluid 20k first time then 30-40k after that. Depending on how much I tow in that time period.

I pull the cabin air filter out when its done then toss it air filter i go till it needs changing usually 40k

Dang I'm surprised at all of these responses. I change my air filter with every oil change regardless. Actually I put a K&N filter in right away then just wash and oil it at every oil change.

 

[Squatch]

I check it a couple times a year, but I don’t change it unless it looks like crap.

I just did the differentials on my 2005 Ford F-350 dually diesel for the first time last year (16 years of service and 120k miles, with many of those miles towing a 5th wheel). Fluid looked fine, no metal to speak of. It won't hurt to change the gear oil in diffs, but nowadays its all synthetic anyway and lasts probably a decade or more.

On my new RAM 2500, I plan on doing 3,000 mile engine oil and filter changes, but likely won't touch the diffs or the transfer case until at least 100k miles. The ZF transmissions don't like new fluid after 100k miles of not being changed. ZF recommends that if the fluid has been in the trans for over 100k miles, recycle it if the trans needs to be drained for any reason. Otherwise, change it before 100k miles...maybe 75k would be good.

I just hit 20,000 miles on my 19’. I take it to the dealer while it’s under full warranty for services. I figure it’s about that time they start telling me I need this service or that service and the bill goes up. Once warranty is up, I’ll do my own oil services. It would be nice to have a pretty solid service interval chart that was in common practice so when the dealer starts asking. I’ll know if it’s really needed or not.

Every 3k definitely is excessive if you use a quality oil that meets or exceeds the specs that are required. I run AMSOIL and the oil hit 7,500 with ease.

There is a chart in the manual.

Maybe so, but oil changes are relatively cheap and I bet if I follow this schedule my truck won't end up with strange noises or premature failures. I do all my own work - I enjoy working on vehicles and machinery. Some engines are more susceptible to oil-related failures than others. I'll err on the side of caution.
