manual 4 wheel shifter on 2016 2500 SRW couple of questions

[PTsideshow]

First off the manual that comes with the truck only covers the electronic knob version.
back in the day the last 4x4 I had had the Warn hubs and you had to turn them on to lubricate them every so many miles. My truck has the shirt on the floor. no where does it mention abouyt putting it 4H or Low to make the front axle turn to lube the scrap iron. What is the consensus of the members on engageing it?

the front end spins all the time. only need 4x4 when you've driven to far in 2wd. lol
anyhow i wouldn't worry about it.

 

[PTsideshow]

Ok Since they didn't have anything in the BOOK I thought I'd ask

 

[JackFate]

Maybe there is more in the series of manuals that you must request? If you don't have them you should their free for the asking.

One question. (because i don't know the answer). Does the CAD version spin all the time?

 

[jhenderson]

The cad disconnects the front axles from one another. The diff spins by way of th spider gears but does not turn the driveshaft and transfer case except by friction from diff lube in cold conditions.

 

[EDankievitch]

It's not a bad idea to cycle the 4x4 system from time to time to keep stuff splashed with lube and seals wet, like you use to do with you'r older truck.

 

[Killer223]

i think the only thing that might get lubed while doing it would be the gears for the actuators... everything else still spins and is lubed. CAD or not. it all still spins.

 

[kthaxton]

Agreed, lots of things are free spinning in there with a CAD, no need to doing anything special to lube things up.

No real "NEED" to cycle into 4x4 per se...

BUT, for the little effort it takes to pull it into 4-High for a few miles around town, I think it's a good preventative.

I do it about once every couple of weeks -- pretty much just when I think about it, and realize it's been a while. Mostly because I've had 4x4 systems fail (come disconnected, lose a wire, something) and not know it until I NEEDED it.

I say it's a no harm no foul matter either way.

Please tell me you don't do this on dry, paved roads!
Running in 4wd on dry, paved (or otherwise hard packed) roads is certainly going to tear things up.....if not an eventual massive failure......very excessive wear on major components.

As said, there is absolutely no reason to do this for "maintenance" purposes, because everything is already bathing in gear oil and spinning, the only difference is the direction it is spinning vs in 4wd.

I can understand this better if I knew what a CAD is.

Google "center axle disconnect"......

I do.

To be fair, I usually do it on a stretch of road I won't be making any turns on...

Just long enough to feel comfortable that everything's still working. I've had a few glitches over the last nearly 30 years with 4x4 units, especially the ones with electrical connections -- usually broken wires. I prefer not to find out something ain't right just as I need it.

I've never broken anything in any of the 8 or so 4x4's I've had...but I do understand that the potential is there.
