These AWD Rogues

[ristau5741]

been reading up on the AWD issues regarding 4 tire replacement if one tire goes bad. there is alot of information, mixed answers regarding year, model, viscous couplings. possibly causing differential, or drive train damage. How do these Rogues fit into all this???? tia

almost all awd vehicles have this "trait". its best to replace 2 or 4 tires at a time to keep things symmetrical.

Considering these vehicles are not "full-time" AWD/4WD vehicles and are primarily FWD vehicles, I wouldnt worry about damaging the drivetrain too much but that is just my opinion.

every single red light, stop sign, driveway, parking spot, etc = its in awd mode. it will bang around. i experienced it first hand when i first got this car. (tires were mix-matched). i made the dealer give me 2 new tires.

Thats interesting... I thought it was always FWD until it sensed slippage or you locked it in AWD. Learn something new everyday.

I guess thats why if you floor it from a stop you never get any chirp. Because all 4 wheels are engaged. Makes sense

My 2015 came with an addendum to the owner's manual mentioning the AWD torque distribution display screen so I don't know if this is a new feature, but I looked at it today when pulling away from a red light under normal acceleration and it showed about 10% power shifting to the rear wheels at the start and dropped back to 0 at around 40mph.

Yes, the 2014 has that same screen and I've seen the same behavior - pretty cool!

I would think that you should replace tires in either pairs or all at the same time.

So then I was 90% right lol. 90% power to the front is pretty much front wheel drive.

There are some AWD vehicles that have a 50/50 split, but the Rogue isnt one of them.

[whizkidtn]

Yes it is. This is much like Subaru's system (and many others) that automatically steer torque to the proper wheels. In normal driving, its mostly a FWD car. You CAN lock it to 50/50 mode by pushing the "AWD Lock" button which you would do from a standing start, say in mud/loose gravel/snow and it AUTOMATICALLY changes back over to "AUTO" mode above 25MPH (you will notice the "AWD Lock" light goes out). If you don't lock the system and get into mud/loose gravel/snow, it will automatically go to 50/50 when it needs to and out of it when it should. See your owners manual for more information.

The 1st gen Rogue only stays locked up to 6mph...

Subaru isnt primarily fwd like our Nissans. Its true full-time AWD.

nope. when it comes to math, you're either right, or wrong. none of this "i was close business lol"

all awd system are asymmetric and symmetric at different times. it just depends when & where. there is no fully 50/50 x 50/50 system unless you physically lock an axle. but then you wouldnt be able to turn unless in mud/ice. one side would be skipping badly.

when on a flat surface such as a road, your tires create grip, and that grip must be mitigated somewhere. its mitigated in the differential. thats where the "open differential" idea came from. but then how do you create traction if one wheel looses it? thats where the LSD(limited slip differential) came from. so an LSD differential allows both tires to rotate at different speeds. but for how long??? how long can an LSD diff function under "slipping" conditions, before the fluid over heats, or something starts to give?
at the heart of slip, is 1 tire that is rotating at a different speed than its partner. so by having tires at differential circumferences, you are placing your differential in a state where its acting as if you are permanently driving on ice/mud/sand.
-and thats just a rear wheel drive car.

now lets add in a transfercase, and a front transmission. Now you have the rear wheels "fighting" the transfercase and front transmission(and final drive).

believe me when i tell you: DO NOT INSTALL 1 NEW TIRE ON AN AWD. you will cause rotational differences that WILL cause damage. if you must mix-match, try your best to do do it in pairs.

I've always replaced my tires in pairs on the same axle as a matter of course. When I went to replace the front pair recently the tire shop told me they "recommendced" i replace ALL 4. I told them where to stick their recommendation. Sounds like an excuse to sell more tires.
