Im sorry but you havent truly tested it then, i love my auto feature too, problem is lock and low still act like auto and spin the rears before engaging, fine for most out there but horrible when you want 4wd and not awd, i know their reason behind it but hell even my wifes little hyundai tucson has the ability to lock in 4wd, it has a speed limiter when engaged but i would be fine with that

Sitting in my truck at a muddy jobsite as we speak. Trying to back up with a small 2500 lb trailer in the rocky mud and the 4wd sounds terrible. Didn't get stuck so I guess it does the job, but the sounds coming from the truck aren't natural.

Now a few weeks ago running around town on snow covered roads, it works just fine. But that's still considered "soccer mom" status in my opinion.

Hmm, I can put it in 4 lock, high or low, idle around the parking lot and it binds when I turn. Feels pretty locked in.

I've experienced no rear wheel spin at all in any lock modes. All or nothing so far.

My wife's Rogue has the ability to lock as well. It binds a hell of a lot more than my truck does in 4"Lock"

I would bet in moments like that you miss your power wagon.

Yes sir, I do. Haha

Has anyone gotten a 2015 CC long box outdoorsman? Did it now come with a 44-45 tcase?

It was supposed to be changed for 2015.

In another thread on here someone posted detailed pics of a 2015 and it looks like it has the 44-45

I had my year on the ice with the truck. Only ran in it 4lock on the lake. I do have nitto's and a lsd in it. Had no troubles. Not that I won't at some point, but not this year. The pic was early season before any real snow.

I know I'm late to the thread (probably get put on a spit) but reading through the comments and yes some 4wd/AWD systems (pg16) are sensitive to wear. My wife's old Subaru cost me close to a grand every time a tire had a nail in it. The only time it works out is if it happens within 4-5k miles of new tires. You can wreak havok on some systems and it's cheaper to replace 4 tires than a transfer case and other components

Is this the old "have to replace all 4 tires on an AWD vehicle"?

I'm not a fan of Subarus, but they're VC diffs are not that sensitive, nor are Haldex systems. Subaru rule of thumb is 1/4" diameter difference, or 4/32 tread depth. If a normal passenger car does roughly 3K miles per 1/32 inch of wear, you're talking 12K miles on your old tires before you're even at their limit; not 4-5K miles.

Nearly 100% of the time the vehicle's differential is seeing varying axle speeds from all 4 corners (just like if all 4 diameters were different); it's called a "differential" because it's controlling the differential between the axles rotational speeds.

They put this stuff in the owner's manual to do two things: sell tires and cover their butts if a rare costly diff repair should arise that should be warrantied. Tire shops and dealers are cautioning against differential repairs because there's money to be made.

Either way, the "Auto 4WD" in your truck is more similar in operating characteristics to a haldex AWD system than the suby symmetrical.

When winter rolls in, I leave mine in 4wd auto.

Subaru Sti owner: aggressive driver

I use 4wd Auto all the time because I’ve gotten spoiled driving my Sti. My daily driver is a 2017 RAM 4x4 with a 5.7 Heim and in 2wd I cant put that power to good use. 4wd Auto lets me put the power where it belongs, on the road. I do 95% in town driving so I get around 12 mpg but I drive it like I stole 100% of the time. Honestly I wish they would have labeled the 4wd Auto “AWD”, it would be much less confusing. Just 2 cents from a guy that’s all about getting from point a to point b as fast as possible all the time. I just like going fast lol.

It isn't AWD. You're doing some damage if you're on dry pavement.

How? That is literally the intended purpose of 4 auto, it can be driven on any surface.

It's says right in the owner's manual that 4Auto can be used year round on all road surfaces

Its the only reason to have it over the other system.

 

[CrispyBacon]

Yes. But if your tires spin, and you actually cause the system to engage, it is a 4wd system at that point. It is NOT awd.

He says he's driving it like he stole it, which probably means he's causing enough wheel slip at the rear the engage the front transfer case. As soon as that happens, it is a 4wd truck, not an awd truck.

Just because it says 4auto, that doesn't mean you want it engaged in situations where a traditional 4wd system would be damaged. If you read up on it, it is very clear that it is not "all wheel drive". It's exactly what it says it is: automatic 4 wheel drive. If it "automatically" engages on dry pavement, you're still driving a 4 wheel drive vehicle on dry pavement.
