So I have a 2003 Forester X 4EAT and a 2006 Outback Limited 4EAT.

It is my understanding from reading MANY threads on here (with somewhat conflicting information) that my cars USUALLY have about a 60/40 split front to rear if in Drive. And that sometimes it can get at slanted as 90/10, and sometimes as even as 50/50.

I have also read that if you start in 1 or 2 (meaning shifter is in 1 or 2, not 1st or second gear in Drive) that the split is automatically 50/50 and that a clutch prevents binding in turns.

Is this true?

I have done searches that led me to this conclusion, but I read some other information that claims that each transmission and model year are different. My purpose for this is for slow offroad driving, and/or getting up and down a steep driveway with snow on it when we're in the mountains. I want to know if there are any benefits to keeping it in 2nd other than the engine braking to limit speed without brakes.

Thanks!

This has been addressed a thousand times on here...with multiple corrections, additions, deletions, flames, threats, death wishes... :)

I'm sure someone will respond.

HAHAHA I know. That's why I am so confused.

Maybe have a sticky that simply states clearly.

"IF YOU HAVE THIS TRANSMISSION YOUR DEFAULT (BEFORE INCLEMENT CONDITIONS) DRIVE SPLIT IS ___ WHILE IN DRIVE AND ___ WHILE IN 1 or 2 ON THE SHIFTER"


I almost did want to ask due to all the conflicting information I have read. I am tempted to just call/write Subaru. It's not in the Subaru AWD explained doc, or the manual (so no RTFM threats), etc...

If you have the MPT layout, then its mostly 90:10 progressing to a NOMINAL (not real) 50:50 as the transfer clutch locks.

If you have VTD then its always the static torque split (60:40 is quoted, but its actually about 57:43 if you measure it) unless slip occurs when the torque split will depned on the amount of locking of the controlled clutch pack within the centre diff.

So: I have the MPT.

I know the 90:10 and 50:50 part. However, what I am asking is this: Will starting out with the shifter in 1 or 2 give me full time 50:50? I get conflicting answers on this. I am beginning to think that no one knows.

Yes it will. If you go out and play in the snow you can really see how it reacts. 1&2 gives you the split, but in 1 you'll just spin all 4 tires. Theres also a mod to force the MPT to lock up. The mpt unfortunately is a pretty terrible setup for offroading, but is pretty good for a daily driver. The VTD setup is very good, I'm pretty disappointed that subaru didn't put it in all XT models at least.

From my (not so pleasant) experience of placing my 04 FXT 4EAT on a Dynapack dyno a long time ago, I can positively confirm that the fronts and rears spin at the exact same rate in 1st and 2nd gear... so yes, 50:50 is correct.

That's exactly what I wanted to hear.

As for testing it on snow... that will have to wait until we move. We don't get too much down here. ;)
